Best Ls Valve Springs for Stock and High-Lift Cams

#1 · Best Overall

1. Michigan Motorsports .600 Beehive Kit

Best for: Street-strip high-lift builds.

Why it ranks #1: Supports up to .600-inch lift, lists 135 pounds seat and 330 pounds open pressure, and includes 16 springs plus 16 seals for specified LS engines.

Support for camshafts up to .600-inch lift is the defining specification here, giving street/strip LS builds a stated ceiling for aggressive profiles. The beehive spring format is paired with 135 pounds of seat pressure at 1.800 inches and 330 pounds open pressure, while the kit includes matching seals.

The .600-inch lift rating gives buyers a clear reference when selecting an aggressive cam, and the listed pressure figures describe the spring’s seat and open loads. Its 16 beehive springs and 16 tophat-style seals arrive as a drop-in kit, so rebuilders get the sealing components alongside the springs rather than sourcing them separately. The stated fit range covers 1997–2013 4.8L, 5.3L, 6.0L and 6.2L LS engines, including several named LS and truck-engine families.

Skip it if you need a stated .660-inch lift ceiling; the BTR SK001 Platinum kit lists that higher limit.

Choose this kit for a street/strip LS build using a cam up to .600-inch lift when having seals included matters. Its stated fit range is specific to 1997–2013 engines, so check the engine family against that list before ordering.

#2 · Highest Lift

2. BTR Platinum .660 Dual Kit

Best for: Steel-retainer .660-inch builds.

Why it ranks #2: Its .660-inch dual-spring rating and stated 155-pound seat and 400-pound open pressures suit higher-lift builds; the listing specifies 15-degree LS heads.

This BTR kit pairs a .660-inch lift rating with steel retainers, giving high-lift LS builds a specified dual-spring package with retainers included. Its listed drop-in fit for 15-degree Gen 3 and Gen 4 LS heads covers a broad set of named engine families.

The dual springs are described as supporting increased seat and open pressure for valve control in high-RPM applications, while the steel retainers add a specified component for the valvetrain assembly. BTR lists 155 pounds at 1.780 inches, 380 at 1.180 inches and 400 at 1.130 inches, with coil bind at 1.070 inches. The drop-in fit covers numerous 15-degree LS heads, including LS1, LS3, LQ4 and LSA, helping buyers check compatibility against the head and engine family.

Skip it if you need a spring kit for a head outside the 15-degree list; Comp Cams 26906-16 is listed for GM LS engines.

This is a fit for LS builders seeking a .660-inch dual-spring setup with steel retainers and published pressure data. Confirm that the head is among the specified 15-degree applications and that the cam’s lift stays within the stated rating.

#3

3. BTR Platinum .660 Kit

• Package Dimensions: 12.24 x 3.78 x 3.11 in
• Weight: 4.42 lb

Best for: Stock-rocker high-lift upgrade.

Why it ranks #3: A .660-inch dual-spring kit for stock-rocker LS applications, with 155 pounds at 1.780 inches and retainers, locators, locks, and seals listed.

A .660-inch lift rating paired with compatibility for stock rocker arms makes this BTR dual-spring kit a clear option for LS cam upgrades retaining factory rockers. The package also lists polished dual springs, retainers, locators, locks and seals, bringing the core valvetrain hardware together.

The .660-inch lift specification establishes its stated range for higher-lift cam profiles, while the dual-spring layout is identified for LS engines using stock rocker arms. Listed loads—155 pounds at 1.780 inches and 380 pounds at 1.180 inches, rising to 400 pounds at 1.130 inches—give builders useful setup data. Compatibility spans 15-degree LS heads, including LS1, LS2, LS3, LS4, LS6, LQ4 and other named variants. Locators are specified for stock guides.

Skip it if you have a non-15-degree head; the Comp Cams 26906-16 is listed for GM LS engines without that head-angle limitation.

This suits an LS cam upgrade that calls for a .660-inch dual-spring kit while retaining stock rocker arms. Its specified fit is for 15-degree LS heads, and its pressure figures provide setup references rather than a substitute for checking the build.

#4 · Broad LS Fitment

4. ISINFLASH .660 Dual Kit

• Package Dimensions: 9.06 x 6.42 x 2.6 in
• Weight: 4.53 lb

Best for: Broad 15-degree LS coverage.

Why it ranks #4: Lists .660-inch dual springs for a range of 15-degree LS heads and engines from 4.8L to 6.2L, though its pressure figures are not provided.

The .660-inch dual-spring rating and a long list of 15-degree LS head applications define this kit’s appeal for higher-lift cam upgrades. It names engines from LS1 through LSA and 4.8L to 6.2L, with steel construction specified for the spring kit.

The .660-inch rating gives builders a stated lift limit for aggressive cam profiles, while the dual-spring configuration is presented for high-RPM operation and valve control. Compatibility spans named 15-degree heads and engine families including LS1, LS2, LS3, LQ4, LQ9 and LSA, which helps buyers compare the listing with their application. The product is also identified for LS engines using stock rocker arms. Unlike listings with detailed pressure figures, the supplied facts provide no specific spring-load measurements.

Skip it if you need published spring-load figures; the BTR SK001 kit lists pressure at three installed heights.

This fits buyers seeking a .660-inch dual-spring kit for a listed 15-degree LS head, including stock-rocker applications. The broad engine list helps with initial screening, but builders wanting load data will need specifications beyond those supplied here.

#5 · Complete Hardware

5. Gasekan SK001S Dual Kit

• Package Dimensions: 9.02 x 6.46 x 2.64 in
• Weight: 4.51 lb

Best for: Complete LS valvetrain hardware.

Why it ranks #5: The package lists 16 dual springs, steel retainers, locators, seals, and 32 locks for Gen 3 and Gen 4 LS engine applications.

Sixteen .660-inch dual springs arrive with steel retainers, stock-guide locators, seals and locks, making this kit’s broad included-parts list its defining feature. Its stated replacement range covers Gen 3 and Gen 4 LS engines, including several common 5.3L, 6.0L and 6.2L variants.

The .660-inch rating sets the listed lift capacity, while the dual springs target the higher-lift upgrade use implied by the package. Including 16 retainers, locators for stock guides, 16 valve stem seals and 32 locks reduces the number of separately listed valvetrain pieces to source. The application list names Gen 3 and Gen 4 LS engines such as LS1, LS2, LS3, LQ4 and LSA. No spring pressure measurements are supplied, so setup planning has less numerical detail here.

Skip it if you rely on published pressure measurements for setup; the BTR SK001 Platinum kit lists several spring-load values.

Pick this kit when assembling a listed Gen 3 or Gen 4 LS valvetrain and wanting springs, retainers, locators, seals and locks together. Its .660-inch rating is clear, but pressure data is not included in the supplied details.

#6

6. BTR LS6 .560 Spring Set

• Weight: 2.77 lb

Best for: LS6-style truck-cam replacement.

Why it ranks #6: The 16-piece LS6-style beehive set is rated for .560-inch lift and is described as a stock-spring upgrade for Gen 3 and Gen 4 LS engines.

The .560-inch lift rating gives this 16-piece LS6-style beehive set a defined target for moderate LS cam upgrades. BTR identifies it as a stock-spring upgrade, and its description specifically pairs the spring style with truck-series camshafts, making that application its clearest use case.

For buyers replacing stock LS springs or pairing springs with a truck-series cam, the .560-inch lift rating sets a concrete limit for cam selection. The LS6-style beehive design is identified as matching the performance of the OEM LS6 spring, while the 16-piece set supplies the springs for an engine set. The supplied information does not list accompanying seals or retainers, so this is best considered when those parts are already accounted for in the valvetrain plan.

Skip it if you want seals included with LS6-style .560-inch springs; Dynosty’s SP011 kit lists springs and hat seals together.

Consider this set for a stock-spring replacement or truck-cam LS build targeting no more than .560-inch lift. The supplied listing identifies 16 springs but does not specify seals or retainers, so plan those components separately if needed.

#7

7. BTR LS6 .560 Spring and Seal Kit

• Package Dimensions: 12.32 x 4.76 x 4.41 in
• Weight: 3.87 lb

Best for: Truck-cam spring-and-seal set.

Why it ranks #7: Pairs .560-inch LS6-style beehive springs with hat seals and lists compatibility with 4.8L through 6.0L engines and stock retainers and locks.

A .560-inch LS6-style beehive spring paired with hat seals is the practical distinction of this BTR package. The listing calls it a match for truck cams such as Truck Norris and Stage 2 Truck Cam, while also positioning it as a replacement for tired stock LS truck springs.

The .560-inch lift rating gives a boundary for choosing a compatible cam, and the stated truck-cam pairings help narrow its intended use. Because the package includes hat seals, spring replacement and sealing components are listed together. Compatibility with stock retainers and locks can simplify parts planning for a build keeping those components. The listing names 4.8L, 5.3L, 5.7L and 6.0L applications, making those engine sizes the clearest fit references provided.

Skip it if you need a stated .660-inch lift rating; the Dynosty BTR SK001 dual kit lists that higher lift capacity.

Choose this package for a listed 4.8L–6.0L LS truck build using a cam within .560-inch lift and retaining stock locks and retainers. Its included hat seals suit buyers wanting those parts bundled with the springs.

#8

8. Michigan Motorsports .550 Beehive Springs

• Package Dimensions: 7.56 x 6.22 x 2.87 in
• Weight: 3.12 lb

Best for: Stock-replacement .550-inch builds.

Why it ranks #8: A .550-inch replacement option for listed LS1, LS2, LS3, LS6, LQ4, and LQ9 engines, with beehive design and GM replacement number 12713265.

Support for camshafts up to .550-inch lift and a stated replacement for GM 12713265 frame these Michigan Motorsports beehive springs as a stock-replacement upgrade. The listing names LS1, LS2, LS3, LS6, LQ4 and LQ9 engines, spanning several car and truck applications.

The .550-inch lift ceiling helps buyers screen cams against the spring’s stated capability, while the beehive design is described as reducing valvetrain mass to aid control at higher RPM. The replacement reference to GM 12713265 gives stock-spring refresh buyers a specific point of comparison. Named applications include LS1, LS2, LS3, LS6, LQ4 and LQ9, with vehicle examples such as Camaro, Corvette, Silverado and Tahoe. The supplied facts describe springs, not a seal or retainer kit.

Skip it if you want hat seals bundled with .560-inch springs; Dynosty’s BTR SP011 kit lists springs and seals together.

Consider these for a stock-replacement LS build or cam upgrade within .550-inch lift across the named engine families. The listing focuses on springs rather than a complete valvetrain kit, so account for seals and retainers separately where your build requires them.

#9

9. COMP Cams LS6+ Beehive Springs

• Weight: 3.07 lb

Best for: Mild LS cam-swap refresh.

Why it ranks #9: Offers 4% higher seat pressure and .030-inch more lift capacity than GM Blue LS6 springs, but the supplied data gives no absolute lift limit.

Four percent higher seat pressure and .030-inch more valve-lift capacity than GM Blue LS6 springs are the specific advantages claimed for this COMP Cams beehive set. Its listing targets mild LS cam swaps and names COMP NSR-series camshafts as compatible applications.

Compared with the stated GM Blue LS6 reference, the higher seat pressure is intended to provide more dynamic valve control, while the added .030-inch lift capacity gives a mild cam-swap builder extra stated room. COMP identifies premium wire and small-batch manufacture as quality features, and lists compatibility with popular GM performance cams and its NSR series. The product is vehicle-specific and the supplied information does not give an absolute lift ceiling, so buyers cannot determine that figure from this listing alone.

Skip it if you need an explicit lift ceiling for cam selection; Michigan Motorsports .600-inch Beehive Springs state one.

This suits an LS owner refreshing the valvetrain for a mild cam swap, especially with a listed COMP NSR-series camshaft. The relative improvements are stated, but an absolute lift limit is not, so that boundary needs resolving for the build.

#10

10. 3mirrors .600 Spring Set

• Package Dimensions: 15.12 x 4.09 x 2.83 in
• Weight: 2.86 lb

Best for: .600-inch LS spring replacement.

Why it ranks #10: Lists .600-inch maximum lift, 318 pounds open load at 1.200 inches, and a 1.140-inch coil-bind maximum, but fitment details are broadly stated.

A stated .600-inch maximum lift and an open load of 318 pounds at 1.200 inches give these 16 LS springs useful selection figures for a cam upgrade. The listing also specifies coil-bind height, spring rate and compatibility across several LS engine sizes.

The .600-inch lift maximum defines the stated cam range, while the 318-pound open load at 1.200 inches and 313-pound-per-inch spring rate offer additional setup figures. A maximum coil-bind height of 1.140 inches adds another measurement for valvetrain planning. The listing names 4.8L, 5.3L, 5.7L, 6.0L and 6.2L LS applications and says the springs exceed the seat-pressure performance of OEM 12499224. High-quality steel is specified for the spring construction.

Skip it if you want a .600-inch beehive kit with seals included; Michigan Motorsports .600-inch Beehive Springs list both.

This suits an LS buyer seeking a spring set with a .600-inch maximum and several published load measurements across listed 4.8L–6.2L applications. The supplied details do not specify seals or retainers, so plan those parts separately if required.
