Fabtech 20-21 GM K2500HD 3.5in Uniball UCA Kit w/Dlss Resi

The Fabtech K1156DL is a 3.5-inch suspension lift system designed specifically for heavy-duty trucks. It features high-quality tubular Upper Control Arms (UCAs) equipped with 1-inch stainless steel uniballs for increased strength and suspension travel compared to factory components. This kit also includes high-performance Dirt Logic reservoir shocks to enhance damping control and ride quality both on and off-road.

This system is engineered to provide a leveled stance while accommodating larger tire sizes, typically up to 35 inches. It is designed for 4WD models of the Chevrolet Silverado 2500 HD and GMC Sierra 2500 HD. The kit is intended to improve ground clearance and off-road capability while maintaining reliable steering geometry.

Installation involves replacing factory upper control arms and installing the included shock absorbers. Professional installation is recommended due to the need for suspension disassembly and potentially specialized tools for alignment.

This kit is designed for the 2020-2026 Chevrolet Silverado 2500 HD 4WD and GMC Sierra 2500 HD 4WD. Ensure verify the specific cab configuration and powertrain compatibility prior to installation. It does not fit 2WD models or other truck platforms.
