      Performance Guaranteed. Fabtech does not disappoint with this lift system that's ideal for everyday drivers and advanced gearheads alike. Indeed, this kit was made using state of the art software, combined with high-end fabrication equipment and a rigorous quality control regimen. This resulted in a reliable lift system that guarantees performance.

      Designed to Withstand Punishment. The Fabtech 6" Performance Lift System was created specifically for rough off-roading. The kit's skid plate and bracketry are constructed from ¼" thick steel to provide maximum strength and optimal reliability. At the same time, the relocation of the front differential results in a noticeable reduction in vibration when driving at higher speeds. What's more, top of the line Dirt Logic shocks ensure superior damping and ride for a smoother driving experience.

      Retains Factory Track Width for a Clean Look. Much work was put into the kit's longer offset ductile steering knuckles, helping it fit with the factory track width while also keeping the tires under the fender. The result is a clean appearance that works properly with StabiliTrak safety functions.

      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" Performance Lift System fits 2014-2018 GMC Sierra 2WD and 4WD vehicles with either a double cab or crew cab. Does not fit Denali models equipped with Magnetic Ride Control.

      Please Note. Some vehicle may experience front driveline vibration while in 4WD. To correct that issue, you'll need Fabtech CV Driveshaft Kit, part# FTS21192.
