Best 5 3 Cam Kit Stage 3 for LS Truck Builds

Best 5 3 Cam Kit Stage 3

A strong Stage 3 cam kit for a 5.3L LS build pairs the right engine fitment with a cam profile and supporting valvetrain parts suited to the intended setup. The Michigan Motorsports Sloppy Stage 3 kit leads this selection with a 238/242 profile, .595-inch lift, 112 LSA, PAC springs, pushrods, and seals. This roundup compares ten options across truck, naturally aspirated, turbo, and Gen V applications, so the name “Stage 3” alone does not determine fit.

Check engine generation, cam gear pattern, converter needs, and included components before choosing. Some listings cover broad LS families; others target a particular truck or forced-induction setup.

The best match depends on your exact engine and build, not just the advertised stage or an aggressive idle description.

The Michigan Motorsports Sloppy Stage 3 kit is the strongest all-around match for a 5.3L Gen 3/4 LS buyer seeking a complete Stage 3 cam package. Its 238/242 duration, .595-inch lift, and 112 LSA provide clear specifications, while the kit includes PAC Racing springs, chromoly pushrods, and hat seals. Confirm your engine and supporting setup before purchase: this aggressive profile is not automatically suitable for every truck, converter, or driving goal.

Detailed Reviews: Best 5 3 Cam Kit Stage 3

Michigan Motorsports Sloppy Stage 3

#1 · Best Overall

1. Michigan Motorsports Sloppy Stage 3

Best for: PAC-spring weekend builds.

Why it ranks #1: Fits Gen 3/4 4.8L–6.2L LS engines and includes PAC springs, chromoly pushrods, and seals with a 238/242, .595-inch-lift profile.

The Sloppy Stage 3 pairs a 238/242 cam profile with genuine PAC Racing 1218 springs and chromoly pushrods, giving weekend LS builders a named set of supporting valvetrain parts. Its description specifically targets a lopey, choppy idle, making sound character as well as the stated cam profile part of its appeal.

The .595/.595 lift and 112-degree LSA specify the cam’s profile, while the included PAC Racing 1218 spring set supplies matched spring hardware. Michigan Motorsports 7.400-inch chromoly pushrods and a hat seal kit are also included, helping consolidate those listed pieces for the installation. Fitment spans Gen 3/4 LS engines from 4.8 through 6.2 liters, including LS1, LS2, LQ4, and LQ9. The description frames it for cars, trucks, and SUVs seeking an aggressive idle.

Pros
  • 238/242 duration and .595/.595 lift
  • Genuine PAC Racing 1218 spring set included
  • Includes 7.400-inch chromoly pushrods and hat seals
  • Listed for Gen 3/4 LS engines from 4.8L to 6.2L
Cons
  • Its described lopey, choppy idle may not suit buyers seeking a mild idle.

Skip it if you want a truck cam specified for a factory torque converter; the Dynosty Texas Speed CHOPacabra is described for that setup.

This kit fits performance-minded LS owners prioritizing an aggressive idle and a supplied set of PAC springs, pushrods, and seals. Its broad engine coverage still calls for matching the listed generation and displacement.

BTSCAR E1841P Stage 3

#2 · Broad LS Fitment

2. BTSCAR E1841P Stage 3

Best for: Broad LS vehicle coverage.

Why it ranks #2: Lists 4.8L, 5.3L, 5.7L, and 6.0L applications and includes pushrods, gaskets, and lifters; verify exact engine fitment and kit contents.

A long vehicle-fitment list is the defining feature of this BTSCAR Stage 3 kit, spanning named LS applications from Camaro and Corvette models to Silverado and Tahoe trucks. It enables buyers to start with specific vehicle and engine coverage, while the title identifies included pushrods, gaskets, and lifters alongside the cam.

The listed coverage includes LS1/LS6 5.7L applications such as Camaro SS and Corvette C5, plus 4.8L, 5.3L, and 6.0L truck applications including Silverado/Sierra and Suburban/Tahoe. That breadth helps owners compare their vehicle against named applications before selecting a kit. The title also identifies pushrods, gaskets, and lifters, consolidating several stated components in one package. Because the supplied details do not state cam timing or lift, use the engine and vehicle fitment as the supported selection guide.

Pros
  • Fitment lists LS1/LS6, LS2, and 4.8L/5.3L/6.0L applications
  • Names Camaro SS, Firebird, Corvette, and GTO applications
  • Includes pushrods, gaskets, and lifters
  • Lists Silverado/Sierra, Suburban/Tahoe, and Avalanche coverage
Cons
  • The supplied listing does not provide cam duration or lift specifications.

Skip it if you need a stated cam profile and PAC spring details; the Michigan Motorsports Sloppy Stage 3 kit lists 238/242 duration and PAC springs.

This is suited to buyers whose LS vehicle appears in its extensive fitment list and who want pushrods, gaskets, and lifters included. Confirm the listed application matters more than published cam-profile figures.

SUSUCAR Stage 3 Truck Kit

#3 · Truck Cam Profile

3. SUSUCAR Stage 3 Truck Kit

Best for: Three-bolt truck conversions.

Why it ranks #3: Targets LS trucks and SUVs with a 218/224, .553-inch-lift, 110 LSA cam and includes springs, seals, and 7.400-inch pushrods.

The SUSUCAR Stage 3 V2 combines a 218/224 profile with .553/.553 lift and includes 7.400-inch chromoly pushrods, .560-inch springs, and seals. That lets eligible LS truck builders address several listed valvetrain components together, while the product clearly identifies its three-bolt cam configuration.

Its 110-degree LSA and 218/224 duration define the stated profile, while the included sixteen .560-inch springs, sixteen hat seals, and sixteen 7.400-inch chromoly pushrods supply matching listed components. Fitment names Silverado, Sierra, Yukon, Tahoe, Suburban, and Escalade applications with 4.8L, 5.3L, 6.0L, and 6.2L engines. The listing specifies a three-bolt cam for Gen III LS and says single-bolt Gen IV setups need a separately purchased three-bolt cam gear conversion kit, an important installation consideration.

Pros
  • 218/224 duration, .553/.553 lift, and 110-degree LSA
  • Includes sixteen .560-inch springs and sixteen hat seals
  • Includes sixteen 7.400-inch chromoly pushrods
  • Names several GM truck and SUV applications
Cons
  • Single-bolt Gen IV setups require a separately purchased three-bolt cam gear conversion kit.

Skip it if you have a single-bolt Gen IV setup and do not want a separate conversion; the Gledewen Stage 3 LS Cam Kit lists a 3-bolt gear attachment.

This suits LS truck and SUV builders whose application matches the named fitment and who want springs, seals, and pushrods included. Single-bolt Gen IV owners must account for the separate conversion kit.

Gledewen Stage 3 LS Truck Kit

#4 · Converter Guidance

4. Gledewen Stage 3 LS Truck Kit

Best for: Truck builds planning converter upgrades.

Why it ranks #4: Offers a 218/224, .553-inch-lift truck cam and lists a 2800–3000 rpm converter as recommended for best overall performance.

The Gledewen Stage 3 truck kit combines 218/224 duration and .553/.553 lift with springs, seals, and 7.400-inch chromoly pushrods. Its guidance also distinguishes between trucks that can work with a stock converter and the recommended 2800–3000 converter for best overall performance, helping set build expectations.

The 110-degree LSA and 218/224 profile define the cam, while the LS6 beehive spring kit, LS hat seals, and chromoly pushrods provide the listed supporting parts. Fitment covers Gen III/IV LS truck engines from 4.8L through 6.2L, and the cam uses a three-bolt attachment. The listing says some trucks will work with a stock converter but recommends a 2800–3000 converter for best overall performance, an important planning point for installation and drivability goals.

Pros
  • 218/224 duration, .553/.553 lift, and 110-degree LSA
  • Includes LS6 beehive springs and LS hat seals
  • Includes 7.400-inch chromoly pushrods
  • Three-bolt attachment and stated Gen III/IV LS truck fitment
Cons
  • Best overall performance is listed with a recommended 2800–3000 converter.

Skip it if you want a factory-converter setup specifically described as suitable; Dynosty's Texas Speed CHOPacabra is designed to work with a factory torque converter.

This is for LS truck builders seeking the listed cam and supporting parts who can plan around the converter guidance. Some stock-converter use is stated, but best overall performance points to a 2800–3000 converter.

Michigan Motorsports BTR Truck Stage 3

#5 · Cathedral-Port Focus

5. Michigan Motorsports BTR Truck Stage 3

Best for: Cathedral-port truck power.

Why it ranks #5: Specifically lists cathedral-port truck engines including LM7, LC9, and LQ4, with .549-inch lift and springs, valve seals, and pushrods.

Brian Tooley Racing’s Stage 3 V3 is specified for cathedral-port LS truck engines, with .549/.549 lift and a 109-degree LSA. The listing connects that application to airflow, mid-range power, and high-RPM performance goals, while the kit title adds a spring kit, valve seals, and chromoly pushrods for the build.

Its 213/22X duration at .050 and .549/.549 lift define the cam specifications, while the 109-degree LSA accompanies the stated mid-range and high-RPM performance focus. The named compatibility list includes LM7, LC9, LQ4, LMG, LR4, L92, L96, and L33 engines, helping cathedral-port truck and SUV builders check their engine against specific codes. The title lists a spring kit, valve seals, and chromoly pushrods with the cam, consolidating key valvetrain parts for an eligible application.

Pros
  • Specified for cathedral-port LS truck engines
  • 213/22X duration at .050 and .549/.549 lift
  • Lists LM7, LC9, LQ4, LMG, LR4, L92, L96, and L33
  • Kit title includes spring kit, valve seals, and chromoly pushrods
Cons
  • Its stated application is limited to the listed cathedral-port LS engines.

Skip it if you need a naturally aspirated cam explicitly listed for LS1, LS2, and LS6 engines; the BTR Stage 3 NA V2 names those applications.

This kit suits cathedral-port LS truck or SUV builders targeting the stated mid-range and high-RPM focus, with springs, seals, and pushrods listed. Engine-code compatibility is the main fit boundary.

BTSCAR Sloppy Stage 3 Kit

#6

6. BTSCAR Sloppy Stage 3 Kit

Best for: Extensive-parts LS projects.

Why it ranks #6: Lists broad LS fitment and an extensive package including springs, pushrods, gaskets, seals, bolts, oil pumps, and a timing chain.

This BTSCAR Stage 3 package names an unusually broad set of installation components: head gaskets, springs, pushrods, oil seals, bolts, oil pumps, and a timing chain. That enables a buyer seeking several listed parts together to plan around a more extensive LS project rather than sourcing only a cam and basic valvetrain pieces.

Its fitment details name LS1/LS6 and LS2 vehicles alongside 4.8L, 5.3L, and 6.0L truck applications, including Silverado/Sierra and Suburban/Tahoe models. The title’s head gaskets, springs, pushrods, oil seals, bolts, oil pumps, and timing chain provide a substantial parts list for planning a broader job. This can simplify component sourcing for an eligible build, though the supplied details do not specify the cam’s duration or lift. Use the named vehicle and engine coverage as the fitment reference.

Pros
  • Lists head gaskets and springs
  • Pushrods, oil seals, and bolts included by title
  • Oil pumps and timing chain also listed
  • Fitment includes named LS and GM truck applications
Cons
  • The supplied listing does not state cam duration or lift figures.

Skip it if you need a stated 238/242 cam profile with PAC spring specifications; Michigan Motorsports' Sloppy Stage 3 kit provides those details.

This is aimed at LS owners planning a parts-intensive project who value the broad component list and have an application named in its fitment details. The unspecified cam profile is a boundary for profile-led selection.

BTR Stage 3 Turbo Kit

#7

7. BTR Stage 3 Turbo Kit

Best for: Turbo LS lightweight valvetrain.

Why it ranks #7: A turbo-oriented 224/24x cam with .618-inch lift and 114 LSA; includes dual springs, titanium retainers, and 7.400-inch pushrods.

This BTR Turbo Stage 3 kit pairs a 224/24x cam profile with dual springs, lightweight titanium retainers, and 7.400-inch chromoly pushrods. The combination targets turbo LS builders seeking more RPM than a Stage 2, with the listing specifically highlighting light-car and S400-equipped 5.3/6.0 builds.

The .618/.618 lift, 114-degree LSA, and three-bolt pattern specify the cam, while BTR Platinum dual springs and lightweight titanium retainers provide the listed supporting valvetrain components. The included 7.400-inch chromoly pushrods add another key part to the kit. Its description points to a light car seeking more RPM than Stage 2 and names a 5.3/6.0 S400-equipped combination, giving turbo builders a concrete use case. Confirm the listed three-bolt configuration suits the intended setup.

Pros
  • Turbo-oriented Stage 3 LS cam
  • 224/24x duration and .618/.618 lift
  • Includes Platinum dual springs and titanium retainers
  • 7.400-inch chromoly pushrods and three-bolt pattern
Cons
  • The cam uses a three-bolt pattern.

Skip it if you need a naturally aspirated street-and-track cam for LS1, LS2, or LS6 engines; the BTR Stage 3 NA V2 is listed for those applications.

This fits turbo LS builders pursuing more RPM, especially the listed light-car and S400 5.3/6.0 combination. Its turbo orientation and three-bolt pattern are the essential boundaries when matching a build.

BTR Stage 3 NA Cam

#8

8. BTR Stage 3 NA Cam

Best for: Naturally aspirated street-track.

Why it ranks #8: Targets naturally aspirated LS applications with a 227/24x profile, .636-inch lift, and 111.5 LSA, rather than a truck-specific kit.

The BTR Stage 3 NA V2 is explicitly a naturally aspirated cam for LS1, LS2, LS6, 5.3L, and 6.0L engines, with .636/.636 lift. Its aggressive profile targets mid-range and top-end performance alongside a choppy idle, making the operating style clear for street and track buyers.

The 227/24x duration, .636/.636 lift, and 111.5-degree LSA describe a high-lift, three-bolt-pattern camshaft. The listing connects its radical profile to increased horsepower and torque, mid-range and top-end performance, and an aggressive exhaust note. Named naturally aspirated applications include LS1, LS2, LS6, 5.3L, and 6.0L engines, giving buyers a defined scope for selecting it. Its street-and-track positioning suits builds pursuing a choppy idle, rather than a mild sound profile.

Pros
  • Naturally aspirated LS application
  • 227/24x duration and .636/.636 lift
  • 111.5-degree LSA and three-bolt pattern
  • Targets mid-range and top-end performance with choppy idle
Cons
  • This is a camshaft listing, not a package listing springs or pushrods.

Skip it if you need springs and 7.400-inch pushrods listed with a turbo cam; the BTR Stage 3 Turbo kit includes both.

This cam suits naturally aspirated LS builders seeking the specified high-lift profile and choppy sound for street or track use. Its listed engine range and three-bolt pattern are important selection boundaries.

TSP L83 Stage 3 V2 Kit

#9

9. TSP L83 Stage 3 V2 Kit

Best for: 2014–2018 Gen V L83 builds.

Why it ranks #9: Fits 2014–2018 5.3L Gen V L83 engines and includes a 222/236, .610-inch-lift cam with springs, phaser limiter, and pushrods.

The Texas Speed L83 Stage 3 V2 is specifically listed for 2014–2018 5.3L Gen V L83 engines and uses a hydraulic roller cam with .610-inch lift. It targets power across 3,000–6,000 RPM, while included springs, a phaser limiter, and pushrods address key parts of this application.

The 222/236 duration and .610/.610 lift pair with a 113-degree LSA, while the listed +10% fuel lobe adds another defining specification. Its stated 3,000–6,000 RPM focus gives street or track builders a clear operating range to consider. Springs, a phaser limiter, and pushrods are included, consolidating several named components for a Gen V L83 build. The listing also describes refined lobe profiles as reducing spring stress and valvetrain noise compared with earlier versions.

Pros
  • Specified for 2014–2018 5.3L Gen V L83 engines
  • Hydraulic roller cam with 222/236 duration and .610-inch lift
  • Includes springs, phaser limiter, and pushrods
  • Targets power across the stated 3,000–6,000 RPM range
Cons
  • Its listed fitment is specific to the 2014–2018 Gen V L83.

Skip it if you need a Gen III/IV LS truck cam for engines such as LM7 or LQ4; the Brian Tooley Racing Stage 3 V3 lists those applications.

This kit suits owners of 2014–2018 L83 trucks or SUVs seeking the stated powerband and included phaser limiter, springs, and pushrods. Its narrow Gen V engine fitment is the decisive boundary.

TSP Chopacabra Truck Cam Kit

#10

10. TSP Chopacabra Truck Cam Kit

Best for: Factory-converter truck builds.

Why it ranks #10: Fits several LS truck displacements and includes springs, seals, and pushrods, but its listing does not identify it as a Stage 3 kit.

The CHOPacabra pairs 214/222 duration and .550/.550 lift with included beehive springs, seals, and OE-replacement pushrods. That package gives LS truck builders core valvetrain pieces alongside a cam specified for a factory torque converter, while targeting the pronounced, snarling idle called out in the product description.

Its 108-degree LSA and 106-degree intake centerline define the cam profile, while the included .560-lift beehive springs and valve seals address supporting valvetrain components. OE-replacement pushrods round out the kit, reducing the need to source those listed items separately. The stated engine range covers 4.8, 5.3, 5.7, 6.0, and 6.2 applications, and the factory-torque-converter design makes this a relevant option for truck builds retaining that converter. Check the listed engine application before choosing.

Pros
  • 214/222 duration and .550/.550 lift specifications
  • Includes .560-lift beehive springs
  • Valve seals and OE-replacement pushrods included
  • Specified for use with a factory torque converter
Cons
  • The stated engine range does not include every LS application.

Skip it if you need a kit specifically listed for 2014–2018 Gen V L83 engines; the Texas Speed L83 Stage 3 V2 kit is specified for those models.

This suits LS truck builders seeking a pronounced idle and a kit with springs, seals, and pushrods included. Its stated engine range and factory-converter orientation are the key boundaries to weigh before selecting it.

Check cam gear pattern before ordering

Cam gear pattern is a compatibility trap: a cam that fits the engine family may still need the correct timing gear arrangement. The SUSUCAR Stage 3 Truck Kit explicitly identifies its cam as a 3-bolt design and says a Gen IV single-bolt setup needs a 3-bolt cam gear conversion kit. That distinction matters more than a broad fitment list covering 4.8L through 6.2L engines.

Confirm the existing cam gear pattern and engine generation before ordering, and verify whether any conversion parts are included; the supplied listing does not say they are. The product descriptions also mix Gen 3/4 LS fitment with different vehicle years, so do not rely on model-year ranges alone.

Check the engine code and hardware in your vehicle, then compare them with the kit’s fitment details and seller information.

Treat converter notes as build-specific guidance

A Stage 3 label does not tell you whether a cam will work well with your existing torque converter. The Gledewen Stage 3 LS Truck Kit says it may work with a stock converter in some trucks but recommends a 2800–3000 converter for best overall performance. By contrast, the TSP Chopacabra description says it was designed to work with a factory torque converter, while the Sloppy Stage 3 kit emphasizes an aggressive, lopey profile without listing a converter recommendation in the supplied facts.

These differences make converter matching a build-specific decision, not a simple ranking by stage number. Consider the vehicle, engine combination, intended use, and cam specifications together, and confirm the final converter and tuning plan with a qualified installer before buying.

How to Choose a 5.3L Stage 3 Cam Kit

Engine family and application

Start by matching the kit to your engine generation and use, rather than relying on “LS” or “Stage 3” alone. The Sloppy Stage 3 kit lists Gen 3/4 engines from 4.8L to 6.2L, while the BTR truck cam specifies cathedral-port applications such as LM7, LC9, and LQ4. The TSP L83 kit instead targets 2014–2018 5.3L Gen V L83 engines.

For a common Gen 3/4 5.3L truck, the Sloppy, SUSUCAR, and Gledewen options are relevant starting points; an L83 owner should focus on the Gen V-specific kit. Verify the exact engine code and vehicle fitment before ordering.

Cam profile and intended powerband

Compare duration, lift, and lobe separation angle alongside the application notes. The Sloppy Stage 3 profile is 238/242, .595-inch lift, and 112 LSA; truck-focused choices include SUSUCAR at 218/224, .553-inch lift, and 110 LSA, and the BTR truck listing at .549-inch lift and 109 LSA. The BTR turbo kit lists .618-inch lift and 114 LSA, while its NA counterpart lists .636-inch lift and 111.5 LSA.

Those are distinct application targets, not interchangeable upgrades. Buyers focused on a truck-specific package should start with truck profiles; turbo or naturally aspirated builds should select a cam explicitly described for that setup.

Included valvetrain and supporting parts

Check the package contents because these kits do not all supply the same supporting components. The Sloppy Stage 3 kit includes PAC springs, 7.400-inch chromoly pushrods, and hat seals. SUSUCAR also lists springs, seals, and 7.400-inch pushrods, while the BTSCAR E1841P listing adds gaskets and lifters.

The BTSCAR Sloppy kit lists an even broader assortment, including head gaskets, bolts, oil pumps, and a timing chain. A buyer replacing several related parts may prefer a more comprehensive kit, while someone sourcing components separately can compare the cam and core valvetrain pieces.

Confirm exact quantities, compatibility, and any parts not explicitly listed before purchase.

Which 5.3L Stage 3 Cam Kit Should You Choose?

For a Gen 3/4 5.3L build seeking a clearly specified, comprehensive Stage 3 package, choose Michigan Motorsports Sloppy Stage 3; it combines a 238/242 profile with PAC springs, pushrods, and seals. For a truck-specific profile with a milder listed duration and the same key valvetrain categories, consider SUSUCAR Stage 3 Truck Kit or Gledewen Stage 3 LS Truck Kit. Gledewen is the one that explicitly discusses a 2800–3000 rpm converter recommendation.

Choose Michigan Motorsports BTR Truck Stage 3 when your engine matches its listed cathedral-port applications. Turbo and naturally aspirated builders should look at the corresponding BTR kits instead.

For a Gen V L83, select the L83-specific TSP kit. Check engine code, gear pattern, and full fitment before ordering.

Frequently Asked Questions

Does a Stage 3 cam require a higher-stall torque converter in a 5.3L truck?

Not automatically; converter needs depend on the cam profile, engine combination, gearing, and intended use. The editorial identifies Gledewen as explicitly recommending a 2800–3000 rpm converter, but that guidance should not be applied to every kit. Confirm the cam maker’s recommendation and your truck’s setup before choosing a converter.

How can I tell whether my LS engine uses a 3-bolt or single-bolt cam gear?

Check the engine’s existing cam gear or timing set: the bolt pattern where the gear attaches to the cam indicates the arrangement. If the engine is assembled, verify its year and engine code against reliable fitment information rather than assuming from displacement alone. Confirm the replacement cam and timing components match before ordering.

What tuning and valvetrain checks should I plan after installing an LS cam kit?

Plan for an ECU tune appropriate to the cam and engine combination, and verify valvetrain compatibility before installation. Check spring suitability, pushrod length, seals, timing components, and clearance requirements against the cam maker’s instructions. Also confirm engine fitment and gear pattern; the listed kits do not establish one universal setup.

Which Stage 3 cam kit suits a naturally aspirated or turbo LS build?

Match the kit to the intended induction type: the roundup lists separate BTR naturally aspirated and turbo Stage 3 options. Do not treat those as interchangeable with a truck-oriented profile. Confirm your engine code, supporting components, and the cam maker’s fitment guidance before selecting a kit.

Is the Gen V L83 kit interchangeable with Gen 3/4 5.3L kits?

No; the listed TSP kit is specifically for the 2014–2018 5.3L Gen V L83, while many other kits target LS or Gen 3/4 applications. Check the engine code and complete fitment details rather than relying on displacement alone, and select an L83-specific kit for that engine.

Final Words

For a Gen 3/4 5.3L build that needs a clearly specified, comprehensive Stage 3 package, the Michigan Motorsports Sloppy Stage 3 kit is the strongest all-around match in this roundup. Choose a truck, naturally aspirated, or turbo profile when that better fits your build, and use the L83-specific kit for a Gen V L83. Before ordering, verify engine code, gear pattern, fitment, converter needs, and supporting valvetrain setup.
