Upgrade your classic truck to a modern driving feel and performance. This kit has everything to convert your front end to coil-overs and a tubular crossmember with rack-and-pinion steering. This is a great way to overhaul your suspension in one go, giving you adjustable ride height to achieve the perfect stance with up to 8” of drop. All while dialing in the ideal ride quality and performance for your application while reducing weight by 140 lbs. over 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.
