Product features and details:

* 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
* Single or double-adjustable shock valving offers independent rebound and compression tunability—great for trucks that will see track time or drivers who really want to dial in ride quality on the street
* 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
