QA1 CROSSMEMBER RETRO FIT KIT FOR 63-72 CHEVROLET C10 TRUCKS

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.

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. 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.

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. 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.

Choose from modular engine mounts (at additional cost) 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.
