Upgrade your '73-'87 squarebody C10 for a significantly improved driving experience and performance while achieving the perfect stance. This kit provides everything you need to convert your Chevy C10's front end to a coil-over setup, complete with a tubular crossmember and rack-and-pinion steering. It’s a great way to overhaul your C10 suspension in one go, giving you adjustable ride height for the perfect stance with up to 8” of drop. All while dialing in the ideal ride quality and performance for your application, and saving 140 lbs. vs stock.
RACK & PINION STEERING
Powered rack and pinion steering offers quicker steering and a tighter feel. Plus, increase steering angle when fitting larger wheels and tires, and improve geometry for enhanced drivability.
INCREASED GROUND CLEARANCE
The factory crossmember and control arms on a C10 sit quite low to the ground. QA1's design raises these components, making the undercab frame rails the truck’s lowest point. To ensure ample shock travel at this lower height, QA1 designed new upper shock mounts that increase travel, delivering a great ride and performance, even at low heights.
MOD SERIES COILOVERS
Take total control of your suspension with 4-way adjustable valving, offering independent tunability of both high and low speed compression and rebound. QA1 MOD shocks offer the most versatile package for ultimate performance in any application. When you are making no compromises, the MOD series coilover is the shock for you.
EASY, BOLT-IN INSTALLATION
The crossmember comes powder coated and ready to install. No need to cut or weld your frame. It easily locates the steering rack, and you can choose mounts (sold separately) for common engines.
MODULAR ENGINE MOUNTS
Choose from modular engine mounts (sold separately) that allow you to reuse your existing transmission mount and driveshaft. Kits are available for small block Chevy, big block chevy and LS applications. DIY mounts are also available if you want to customize the location of your engine.
