Quick Overview

Stand apart from the competition with this Fabtech 6” lift kit for your Silverado or Sierra 3500HD. Using their cutting edge RTS® design, this Fabtech lift kit features a bracket system to retain the torsion bars in the factory location providing superior ground clearance at the frame. This protects the torsion bars from becoming damaged when off-roading while giving your truck a clean appearance. A smooth highway ride is retained as well as the factory load carrying capacity for trucks used for towing or hauling.


Lower control arm crossmembers are arched at the bottom for increased ground clearance and include a skid plate that protects the front differential from off-road obstacles. Fabtech uses ¼” thick steel to construct the crossmembers and bracketry for additional strength and rigidity to the vehicle’s suspension. This lift kit is designed for ease of installation requiring only 4 holes to be drilled and requires no cutting of the front differential housing.


Fabtech Dirt Logic 2.25 shocks are pre-tuned for each Fabtech suspension lift kit, accounting for larger tires, providing the finest all around damping. These shocks feature 2.25″ OD Aluminum Reservoir w/-6 Stainless Steel O-ring Hose, a 2.25” OD stainless steel body with 2.0” OD Billet aluminum piston and 7/8” NitroSteel® Black Piston Rod. Included in this lift kit for your Silverado or Sierra are the following:
