GM Platform Coilovers (A/G/F-Body)

GM coilovers are not one bucket: the platform and the generation decide the kit, and the same nameplate can take a completely different set two model years apart. This page pulls together the application-specific kits we currently have in stock for the three classic GM rear-drive platforms - 24 kits from QA1, Aldan American and Ridetech, from $697.95 to $2,130.95 - organized by A-Body, G-Body and F-Body, front, rear and front-and-rear sets, single and double adjustable. Every kit listed is in stock and ready to ship, and every order over $200 ships free.

START WITH THE PLATFORM AND THE YEARS - NOT THE NAMEPLATE ALONE

The listings on this page split the platforms by generation, because the kits do. A-Body here runs in three cuts: 1964-67 (the QA1 GS501 front kits, listed for GM A-Body 1964-67 in 350 and 450 lb/in), 1968-72 (the deepest bench on this page - QA1 and Aldan front kits, QA1 and Aldan rear kits, and Aldan front-and-rear sets), and 1973-83 (QA1's GS401 front kit is listed for GM A-Body 1973-83, and Aldan's RCX front kits for A-Body 1973-77). G-Body is the 1978-88 generation: Aldan and QA1 front kits, QA1 rear kits in single and double adjustable, and an Aldan front-and-rear set listed for the small-block cars. F-Body splits three ways again: 1967-69 (Ridetech HQ front and rear pairs and an Aldan front kit that also covers 1968-74 X-Body), 1970-81 (Aldan's front kit and QA1's double-adjustable GD501 front kit, both listed for GM F-Body 1970-81), and 1982-2002 (QA1's rear systems for Gen 3 & 4 Camaro, single and double adjustable). Two Aldan RCX front kits deliberately span the A-to-G changeover - they are listed for GM A-Body 1973-77, G-Body 1978-88 and X-Body 1975-79 in one part number. The rule that follows from all of that: match the kit to your car's platform and year range as the listing states it, and if your car sits on a changeover year, read the individual listing twice.

FRONT, REAR, OR BOTH ENDS

These kits are sold the way the brands merchandise them: as a front pair, a rear pair, or a front-and-rear set. Front-only and rear-only are both legitimate ways to do this job - a front Pro-Coil conversion is the common first step on an A-Body, and the rear kits here are complete rear systems in their own right. The two front-and-rear sets on this page (Aldan's for 1968-72 A-Body and for 1978-88 G-Body) take the matching question out of it by pairing the ends in one box, with the front and rear spring rates stated separately in the listing - 550 front / 160 rear on the A-Body set, for example. What this page does not do is mix ends across part numbers for you: if you pair a front kit and a rear kit yourself, you are the one matching spring rates and adjustability across the car.

SINGLE ADJUSTABLE OR DOUBLE ADJUSTABLE

Every kit here is one or the other, and the listing says which. A single-adjustable kit gives you one damping adjustment per shock; a double-adjustable kit separates the compression and rebound adjustments so each can be set on its own. The single-adjustable kits anchor this page's ladder (the Aldan Phantom and QA1 Pro-Coil front and rear kits, and Ridetech's HQ Series pairs), and the double-adjustable kits sit a step up (QA1's GD front and double-adjustable rear kits, and Aldan's RCX Series). Neither is "better" in the abstract: single adjustable is the simpler street setup to live with, and double adjustable is the choice when you intend to tune compression and rebound separately - at the drag strip, autocross or on track. All of the kits on this page are listed as twintube designs except Ridetech's HQ Series pairs, which are listed as monotube.

SPRING RATES ARE STATED PER KIT - READ YOUR LISTING

There is no honest platform-wide spring-rate chart, and this page does not print one. The rates are stated in each kit's own listing because they belong to that kit, that end of the car, and that spring: front rates on this page run from 350 lb/in (QA1's small-block A-Body 1964-67 kit) through 400, 450 and 550 lb/in to the 700 lb/in in Ridetech's 1967-69 Camaro front pair, and rear rates run from 140 to 220 lb/in. Some listings also state the front-axle weight band the kit is built around (QA1's GS401 listings state 1801-1900 lb, for example). So the order of operations is: pick the kit that fits your platform and years first, then read its stated spring rate and weight band, and if the rate does not match how your car is built and used, pick the sibling kit in the other rate rather than assuming one rate suits every car on the platform.

QUESTIONS GM OWNERS ASK US

Which platform is my car? The fitment lists in these products name them out: Chevelle / Malibu, El Camino, Buick Skylark, Oldsmobile Cutlass / 442 and Pontiac GTO / Tempest / LeMans appear in the A-Body listings; Malibu, El Camino, Monte Carlo and Buick Regal (including GN) appear in the 1978-88 G-Body listings; and the F-Body kits are listed for Camaro by generation (1967-69, 1970-81, and Gen 3 & 4 1982-2002). If your model is not named in a kit's listing, do not assume the platform label alone covers it - call us and we will check the manufacturer's application for your exact car.

Can I do just the front now and the rear later? Yes - front and rear kits on this page are sold as separate pairs, and nothing in the listings requires buying both ends at once. The front-and-rear sets exist for owners who want the ends matched in one purchase. Either way, keep the paperwork: the rear kit you buy later has to suit the same platform generation as the front kit you already fitted.

Will a rear coilover kit just bolt onto my leaf-spring 1967-81 F-Body? Be careful here. The early F-Body rear kits on this page are the Ridetech HQ rear pair listed for 1967-69 - converting a leaf-spring car to rear coilovers is a conversion job, not a shock swap, and the maker's instructions for the specific kit govern what it needs. The 1982-2002 QA1 rear systems are a different case: those cars left the factory on rear coil springs, and the kits are listed for that generation. If you are planning a leaf-to-coilover conversion, talk to us before ordering so the kit and the conversion hardware are planned together.

How much will a kit lower my car? The listings on this page do not state a drop figure, so this page does not promise one. Ride-height adjustment range is a per-kit specification: if a specific drop is the point of your build, that is a question to settle against the manufacturer's data for the exact part number before you order - call us at 213-549-4279 (Mon-Fri, 9am-5pm PT) with your platform, year and the kit you are looking at, and we will go through its listing with you. The QA1 and Aldan listings here both state that professional installation is recommended, and we echo that: these kits set the car's ride height and damping, and they deserve a proper alignment afterward.
