QA1 Coil-Over And Crossmember Kit for 1973-1987 Chevy C10
Upgrade your classic truck to a modern driving feel and performance. This kit has everything you need to convert your front end to coil-overs and a tubular crossmember with rack-and-pinion steering. It’s a great way to overhaul your suspension in one go, giving you adjustable ride height for the perfect stance with up to 8” of drop. All while dialing in the ride quality and performance level for your application, and saving 140 lbs. of weight vs stock.
Rack and Pinion Steering
Update your truck to a powered rack-and-pinion for quicker steering and a tighter feel. Plus, increase steering angle when fitting larger wheels and tires, and improve your geometry for enhanced drivability.
Increased Ground Clearance
The crossmember and control arms make your undercab rails the truck’s lowest point for 2” of additional ground clearance. New upper shock mounts increase travel for a great ride and performance, even at low ride heights.
Adjustable Shock Valving
Single-adjustable shocks make it easy to tune your ride quality in seconds with the twist of a knob.
Easy, Bolt-In Installation
The crossmember comes powder coated and ready to install. You do not need to cut or weld your frame. It easily locates the steering rack, and you can choose engine mounts (sold separately) for a number of common engines.
If you already have QA1’s coil-over system, you can find retrofit kits to use your existing components
