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

When you're looking to give your 2011-2019 Chevrolet Silverado 2500 HD or 3500 HD, or its GMC Sierra counterpart, a significant stance upgrade, this 4-inch Ultimate System from Fabtech is a comprehensive solution. What you get in this kit are the core components to lift your truck and improve its off-road capability. This includes heavy-duty ductile iron steering knuckles, forged torsion bar keys designed to provide the necessary lift without causing excessive CV joint strain, and a pair of front 2.5 Dirt Logic Stainless Steel coilover shocks along with rear 2.25 Dirt Logic Stainless Steel shocks.

The heart of this system lies in its Uniball Upper Control Arms. These arms are constructed from .120-inch wall 4130 Chromoly tubing and utilize 1.50-inch OD 1-inch FK Stainless PTFE Uniballs. This robust setup is engineered to allow for up to 9 inches of front wheel travel, giving you more capability when tackling rough terrain. The system is designed to level out the factory nose-down rake, providing a more aggressive stance. If you prefer a slight factory nose-down appearance, an optional 1-inch rear block kit is available separately.

This kit offers a substantial lift and improved suspension articulation. The Dirt Logic shocks are built with stainless steel bodies for durability and corrosion resistance. The Uniball Upper Control Arms can also be purchased separately to upgrade existing Fabtech or other aftermarket suspension systems, highlighting their value as a standalone component for enhanced performance.
