Fabtech 11-19 GM C/K2500HD/3500HD 4in Ultimate System w/Perf. Shocks

If you're looking to give your 2011-2019 Chevrolet Silverado 2500 HD or 3500 HD, or its GMC Sierra counterpart, a significant boost in height and capability, this Fabtech 4-inch Ultimate System is a solid option. This kit is designed to raise your truck's stance, allowing for the fitment of larger tires and improving its off-road presence and street appeal.

This Ultimate System takes a different approach than some budget kits. Instead of just using spacers, it incorporates replacement upper control arms made from strong 1.50-inch OD, .120-inch wall DOM tubing. These arms connect to heavy-duty ductile iron steering knuckles, ensuring a well-built front end. The factory torsion bars are retained but use new forged adjusting keys to achieve the desired 4 inches of lift. For the rear, the lift is achieved using lift blocks and extended u-bolts, providing a balanced increase in ride height. This setup is engineered to work with the factory steering components, including a Trac Bar relocation bracket that centers the axle without needing to swap the Pitman arm, which can simplify installation and reduce costs.

With this kit installed, you'll be able to fit 33-inch or even 35-inch tall tires, though some trimming of the inner fender wells will be necessary for adequate clearance, especially for off-road use. The system includes performance shocks to complement the lift and help maintain a comfortable ride quality. This kit is a comprehensive solution for those wanting a noticeable lift and the ability to run larger rubber on their heavy-duty GM truck.
