      Designed with Cutting Edge Technology. As a creator of aftermarket suspension systems, Fabtech has received numerous awards for their market-leading designs.  Indeed, this performance lift system was made using state of the art software combined with high-end fabrication equipment. The end result? A high-performance system that every type of driver can appreciate.

      Made for the Great Outdoors. This performance lift system was created with true off-roaders in mind. Notably, the skid plate and all bracketry are constructed from ¼" thick steel to provide extra strength, improved protection, and optimal reliability. For extra stability, the front differential is relocated, resulting in a noticeable reduction in vibration when driving at higher speeds. At the same time, the addition of Dirt Logic Shocks offers superior cushioning to help navigate rough roads.

      Near-Factory Looks. This kit retains your vehicle's factory track for much easier installation. When combined with the offset ductile steering knuckles, this also keeps the tires under the fenders for a clean look.

      Two Versions Available.
      This Fabtech Kit is available in two versions. There is an option for Sierras equipped with an Aluminum Alloy or Stamped Steel Front Suspension. And there is an option for Sierra models equipped with a Cast Steel Front Suspension. Please be sure to choose your suspension from the options listed above.

      Application. The Fabtech 6" Gen II Performance Lift System fits 2014-2018 GMC Sierra 2WD/4WD crew cab and double crew models.

      Technical Note. This Kit is not compatible on Denali Models equipped with MagneRide Suspension.
