The Fabtech 4in Ultimate System fits the 2015-2019 GMC Sierra 3500HD and delivers 4 inches of lift with performance shocks for improved offroad capability.

Install Difficulty: Professional Install Only
Full lift kit install requires a vehicle lift, suspension disassembly, radius arm drop bracket installation, and rear u-bolt torque work; typically takes 8-10 hours. Professional alignment required after installation.

Product Overview

This system retains the factory front coil springs with a steel upper spacer to deliver 4 inches of front lift. Radius arm drop brackets preserve factory arms with correct caster geometry for the new ride height.

A trac bar relocation bracket centers the axle and works with the factory pitman arm, cutting install time and cost. Rear lift is achieved with lift blocks and extended-length u-bolts.

Fits 35in tall tires with inner fenderwell trimming required for street and light offroad clearance.
