QA1 Crossmember Retrofit Kit for 1963-1972 Chevy C10
Already have a QA1 coil-over conversion system on your C10? This bolt-in upgrade adds powered rack-and-pinion steering, offers 2” of additional drop range (up to 8” total) and saves an additional 70 lbs of weight. The result is improved drivability and steering feel while achieving the perfect stance.
Rack and Pinion Steering
A powered rack-and-pinion provides quicker and tighter steering. Plus, increase steering angle when fitting larger wheels and tires and improve geometry for enhanced drivability.
Improved Ground Clearance
The tubular design makes your undercab rails the truck’s lowest point. Updated lower shock mounts add 2” of clearance. New upper shock mounts increase travel for a great ride and performance, even at lower ride heights.
Compatible With Existing QA1 Coil-Over Systems
Easily swap out a few components on your existing QA1 shocks and control arms. This means you can upgrade your truck in stages, starting with coil-overs and control arms.
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 mounts (sold separately) for common engines.
This kit does not include shocks, springs or control arms – these are included in QA1 coil-over systems. Additional kits are available with these included.
Includes updated hardware for existing QA1 sway bar
