Fabtech 01-06 GM C/K2500HD 8in Perf Sys w/Perf Shks

If you're looking to give your 2001-2006 Chevrolet Silverado 2500 HD or GMC Sierra 2500 HD a serious upgrade in stance and capability, this 8-inch Performance Suspension System from Fabtech is a well-built option. It's designed to provide a true 8 inches of lift without needing to adjust your torsion bars, which is great because it means you can fit up to 37-inch tall tires right out of the box. This system is all about maximizing your ground clearance and improving your truck's off-road presence.

The core of this system includes one-piece cast drop down steering knuckles that connect to heavy-duty, 1/4-inch thick lower control arm crossmembers. These crossmembers have a high arch design to help with clearance. Fabtech also includes new tubular upper control arms that use urethane bushings for a solid feel and fit into the stock frame pockets. To ensure proper driveline angles, especially with the stock driveshaft, the front differential is relocated. The rear of the truck is lifted with a 4-inch block kit and 2-inch add-a-leafs, and the kit also includes rear bump stop brackets and a carrier bearing drop bracket to keep everything aligned.

This kit comes complete with performance shocks to complement the suspension lift. The upper control arms even feature double shock mounting tabs, giving you the option to add Fabtech's dual shock hoop system later if you want even more damping control. With over 20 years of experience, Fabtech has engineered this system to offer an excellent ride quality along with the increased ground clearance you're looking for.
