Best Air Suspension To Coil Spring Conversion Kit

#1 · Best Overall

1. Part Synergy Ram Kit

• Weight: 83 lb
• Material Type: Steel
• Compatible with Vehicle Type: Truck

Best for: Ram 1500 full-vehicle conversion.

Why it ranks #1: Covers front and rear Ram 1500 suspension and includes an electronic bypass module, making it the most complete listed option for its stated application.

A front-and-rear package with an electronic bypass module distinguishes this Part Synergy kit, enabling a whole-vehicle conversion of 2013–2018 Ram 1500 factory air suspension. It uses progressive-rate coil springs and includes components for both suspension ends, rather than limiting the conversion to the rear.

Front and rear conversion components let Ram 1500 owners address both axles with one kit, while progressive-rate coil springs replace the factory air setup. The included electronic bypass module supports compatible vehicle systems after conversion, an important part of the package beyond the suspension hardware. The listing specifies 2013–2018 Ram 1500 fitment and steel construction; its 83-pound listed weight is also relevant when planning delivery and handling.

Skip it if you only need rear conversion parts; A-Premium's Ram 1500 kit is rear-specific and includes shocks, springs, and isolators.

Ram 1500 owners from model years 2013–2018 seeking front and rear conversion components plus an electronic bypass module are the intended buyers. The stated application does not include other Ram model years.

#2 · Complete Four-Corner Set

2. Complete Struts Navigator Kit

• Material Type: Metal
• Compatible with Vehicle Type: Car

Best for: Navigator complete strut set.

Why it ranks #2: Includes front and rear components for Lincoln Navigator models and is listed as a set of four for FWD and AWD configurations.

A set of four ready-to-install front and rear assemblies distinguishes this Complete Struts kit for 2003–2006 Lincoln Navigator models. It converts air suspension to shocks and coil springs at standard height, and the listing specifies fitment for both front-wheel-drive and all-wheel-drive models.

The four-assembly package covers front and rear, so the listed conversion addresses the vehicle as a set rather than only one axle. Its shocks and coil springs are described as ready to install and convert the air setup to standard ride height. Complete Struts also states that the kit fits original mounting points without modifications, while noting that an alignment is needed after installing new struts to restore factory configuration.

Skip it if you need a conversion kit for a different vehicle; Monroe's 90032C2 is listed for Jeep Grand Cherokee applications.

Lincoln Navigator owners with 2003–2006 FWD or AWD models seeking a complete front-and-rear conversion to shocks and coil springs are the target. Plan for an alignment after installation.

#3 · Best Full-Vehicle Kit

3. Suncore Range Rover Kit

• Weight: 60 lb

Best for: Range Rover four-corner kit.

Why it ranks #3: Includes front and rear coil springs, dust boots, spring seats, top plates, and bushings for specified Range Rover models, with exclusions stated.

Four coil springs for the front and rear make this Suncore kit a full-vehicle conversion option for 2003–2012 Land Rover Range Rover models. It enables replacement of the factory air suspension with conventional springs, while excluding Supercharged, Sport, and Evoque models from the stated application.

The kit includes two front and two rear coil springs, plus dust boots, spring seats, top plates, and bushings. Those supporting components accompany both axles, making it a more complete conversion package than a rear-only kit. Suncore also states that its components require no modifications for direct fitment. The fitment exclusions are significant: the listing does not cover Supercharged, Sport, or Evoque models, so the vehicle’s version matters.

Skip it if you own a Supercharged, Sport, or Evoque model; this kit explicitly excludes those versions, while Suncore's 150G-30-R-RES is a rear truck conversion.

Owners of a 2003–2012 Land Rover Range Rover outside the listed exclusions seeking a front-and-rear air-to-coil conversion are the target. The model-version exclusions are the critical fit boundary.

#4

4. A-Premium Ram Rear Kit

• Material Type: Alloy Steel
• Compatible with Vehicle Type: Truck

Best for: Ram 1500 rear conversion.

Why it ranks #4: Fits Ram 1500 and 1500 Classic applications and itemizes rear shocks, coil springs, bump stops, and both small and large isolators.

A complete rear kit for Ram 1500 applications pairs gas shocks with coil springs, enabling conversion from rear air springs to conventional suspension in one package. It covers Ram 1500 model years 2013–2018 and Ram 1500 Classic 2019–2023, with listed spring seats and bump stops included.

The set includes two rear gas shock absorbers and two coil springs, so the core conversion parts arrive together for both sides. Four isolators and two bump stops round out the supplied components, helping provide the supporting pieces needed for assembly. Double-pipe shocks have a listed 9.13-inch stroke and 16.61-inch compressed length; these dimensions identify the shock configuration for the specified application. Fitment is limited to the listed Ram 1500 and 1500 Classic years.

Skip it if you need front and rear conversion parts together; Part Synergy's Ram 1500 kit includes both ends and an electronic bypass module.

Ram 1500 and Ram 1500 Classic owners seeking a rear-only air-to-coil conversion get shocks, springs, isolators, and bump stops in one set. Check the listed model-year range, since this kit does not cover front suspension.

#5

5. TRQ Rear Conversion Kit

• Weight: 25.5 lb

Best for: Three-row GM SUV rear kit.

Why it ranks #5: Lists rear fitment for Trailblazer EXT, Envoy XL, Envoy XUV, and Ascender, with the Ascender application specifying seven-passenger seating.

TRQ lists rear conversion coverage for several three-row GM SUVs, including Trailblazer EXT, Envoy XL, Envoy XUV, and seven-passenger Ascender applications. The air-bag-to-coil kit enables a rear suspension conversion, while TRQ’s catalog of DIY videos offers a viewing resource for replacement-part installation.

The named application range spans Chevrolet Trailblazer EXT 2002–2006, GMC Envoy XL 2002–2006, GMC Envoy XUV 2004–2005, and Isuzu Ascender 2003–2008 with seven-passenger seating. That specific fitment helps narrow the kit to the listed rear applications. TRQ also describes hundreds of DIY videos and a “View Before You Do” approach, giving home repairers a way to consult installation guidance before starting the job.

Skip it if you need both axles converted in one package; Suncore's 2003–2012 Range Rover kit includes front and rear coil springs.

Owners of the listed Trailblazer EXT, Envoy XL or XUV, and seven-passenger Ascender models seeking a rear air-to-coil conversion are the target. Confirm that the intended application falls within the stated years and seating configuration.

#6 · Electronic Bypass Included

6. Suncore Rear Electronic Kit

• Weight: 15 lb
• Material Type: steel or aluminum
• Compatible with Vehicle Type: Truck

Best for: GM SUV rear shock conversion.

Why it ranks #6: Converts rear air shocks to coil-over gas shocks and includes resistors and a ride-light bypass kit for listed Cadillac, Chevrolet, and GMC vehicles.

Rear gas shocks with helper springs and a resistor ride-light bypass kit define this Suncore conversion, enabling a change from air shocks to passive coil-over shocks. Listed applications include Cadillac Escalade variants, Chevrolet Avalanche and Suburban models, and GMC Yukon variants.

The package includes two rear gas shocks with helper springs and two resistors, combining the suspension hardware with a ride-light bypass component. That pairing supports a rear conversion from air shocks to passive coil-over shocks while addressing the listed electronic warning-light function. The stated vehicle coverage spans several Escalade, Avalanche, Suburban, and Yukon configurations; buyers should match the specific model and variant to the supplied application listing.

Skip it if you need front and rear springs for a Range Rover; Suncore's 72R-30-4-002 kit includes coil springs for both ends.

Owners of the listed Escalade, Avalanche, Suburban, or Yukon applications seeking a rear air-shock-to-passive-coil-over conversion are the intended buyers. Its rear-only scope is the main boundary for a full-vehicle conversion.

#7

7. Monroe Grand Cherokee Kit

• Weight: 23 lb

Best for: Jeep Grand Cherokee conversion.

Why it ranks #7: Provides a vehicle-specific air-to-coil conversion for Jeep Grand Cherokee, with application-tuned shock or strut, springs, and hardware described.

Monroe names the Jeep Grand Cherokee as the application for this air-spring-to-coil conversion kit, enabling a transition from factory-equipped air suspension to conventional suspension. Its description identifies an application-tuned shock or strut, coil spring components, and hardware as the kit’s core contents.

An application-tuned shock or strut accompanies coil spring components and hardware, connecting the conversion parts to the named Jeep application rather than presenting a general-purpose spring set. Monroe states that the kit converts factory air suspension to conventional suspension. The supplied information does not specify model years, axle position, or component count, so the vehicle name and those undisclosed details define the practical fitment boundary.

Skip it if you need a stated model-year range or a full front-and-rear kit; Suncore lists both ends for 2003–2012 Range Rover.

Jeep Grand Cherokee owners seeking a Monroe conversion from factory air suspension to conventional components are the intended buyers. The listing omits model years and axle position, so those application details are a key boundary.

#8

8. Monroe Grand Marquis Kit

• Weight: 0.27 g
• Material Type: Metal
• Compatible with Vehicle Type: Car

Best for: Mercury Grand Marquis conversion.

Why it ranks #8: Targets Mercury Grand Marquis and describes a conventional conversion with an application-tuned shock or strut, coil springs, and hardware.

Monroe identifies the Mercury Grand Marquis as the application for this air-spring-to-coil conversion kit, enabling a change from factory-equipped air suspension to conventional suspension. The description says the package includes an application-tuned shock or strut, coil spring or springs, and hardware for the vehicle-specific conversion.

The application-tuned shock or strut is paired with coil spring components and hardware, which keeps the conversion elements together rather than requiring a separate generic spring selection. Monroe describes the result as conventional suspension in place of factory air suspension. The supplied listing names the Mercury Grand Marquis but gives no model years or component count, so buyers should use the vehicle-specific listing details to assess the intended application before ordering.

Skip it if you need stated model-year coverage or a front-and-rear kit; Complete Struts lists a 2003–2006 Navigator set of four.

Mercury Grand Marquis owners looking to replace factory air suspension with conventional components can consider this Monroe kit. Its listing names the vehicle but not model years or component count, making those details important boundaries for selection.

#9

9. Marketplace GX470 Kit

Best for: Lexus GX470 rear conversion.

Why it ranks #9: Identifies a rear air-spring-to-coil conversion for GX470, but the supplied listing gives little detail about included components.

A rear air-spring-to-coil conversion listed for 2003–2009 Lexus GX470 models gives this Marketplace Auto Parts kit a focused application. It enables replacement of rear air springs with coil springs, with the product title identifying the vehicle range and conversion direction.

The listing specifies rear fitment and a 2003–2009 GX470 application, helping owners identify whether the kit matches the vehicle and axle they intend to convert. It provides no further supplied details about included components, shock type, or installation hardware, so the stated scope is the main basis for evaluation. Buyers seeking a narrowly identified rear conversion can use the product’s vehicle and position description to guide selection.

Skip it if you need named shocks, springs, and supporting hardware in the listing; A-Premium's Ram 1500 rear kit specifies those components.

Lexus GX470 owners with 2003–2009 models seeking a rear air-spring-to-coil conversion are the intended buyers. The listing provides the application and position but little component detail, which is an important selection boundary.

#10

10. Sawyer Auto Rear Kit

Best for: Escalade rear passive conversion.

Why it ranks #10: Lists rear fitment for Cadillac Escalade applications and describes a direct replacement, but provides limited detail about the kit contents.

A direct-fit rear conversion for 2002–2014 Cadillac Escalade models enables replacement of air suspension with passive coil-spring shocks. Sawyer Auto describes the part as a factory-style replacement, making its stated appeal a focused rear application rather than a front-and-rear conversion package.

The product is specified for the rear of 2002–2014 Cadillac Escalade models, which gives buyers a defined vehicle and axle scope. Sawyer Auto describes it as a direct-fit replacement that installs like the factory unit and says it is manufactured as an upgrade from original materials. The listing does not provide a component count or detailed contents, so the stated rear application and replacement format are the available planning details.

Skip it if you need a full front-and-rear conversion with listed components; Suncore's Range Rover kit specifies springs and supporting parts for both ends.

Cadillac Escalade owners from model years 2002–2014 seeking a rear passive coil-spring shock conversion are the intended buyers. The listing’s rear-only scope and unspecified component contents are important boundaries.
