Full 4in suspension lift install requires a vehicle lift, suspension disassembly, and specialty tools; typically takes 8-12 hours. Professional alignment required after installation.

Product Overview

This complete lift system raises the 3500HD 4 inches using engineered brackets, crossmembers, and hardware designed to work with the factory steering centerlink and upper control arms.

Fabtech Performance Shocks are tuned to the new geometry to control body motion at highway speeds and soak up hits on the trail.

The kit installs without welding and clears stock tires and wheels, making it a strong platform for future tire upgrades.
