Upgrade Square Body for much-improved driving feel and performance while getting the perfect stance. This kit has everything you need to convert your Chevy C10's front end to coil-overs and a tubular crossmember with 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 and Pinion Steering

Powered rack-and-pinion 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 crossmember and control arms make your undercab rails the truck’s lowest point. 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. 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.

Front Sway Bar

The optional front sway bar (sold separately) adds even more cornering capabilities. It reduces body roll and keeps your tires planted to give you more grip in the turns.
