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

The upper control arms on this Fabtech 4-inch lift system are built from 1.50 inch OD, .120 inch wall DOM tubing, a strong material choice that attaches to heavy-duty ductile iron steering knuckles. This system is designed for 2011-2019 Chevrolet Silverado 2500 HD and 3500 HD trucks, as well as their GMC Sierra counterparts. It provides a 4-inch lift, allowing you to fit larger tires, up to 33 or 35 inches tall, with some cutting required for clearance. This setup is a great way to level out the factory nose-down rake on your truck, giving it a more aggressive stance without altering the rear suspension.

Fabtech engineered this kit so the factory torsion bars stay in their original position. New forged adjusting keys are included to achieve the desired lift height. A notable benefit is that there's no loss of ground clearance because the stock lower control arms, torsion bars, and front differential are not relocated. This means the critical undercarriage components remain where they are, simplifying installation and maintaining factory ground clearance where it matters most.

This Ultimate System comes complete with front and rear 2.25 inch Dirt Logic Stainless Steel shocks. These shocks are known for their performance on and off-road. If you prefer a slight factory nose-down appearance, an optional 1-inch rear block kit is available separately for both 2500 HD and 3500 HD models.
