      Award-Winning Design. It doesn't matter if you're a simple everyday driver or a certified gearhead. Fabtech once again made a product that's made from the latest technological processes and has undergone thorough quality control procedures. This has resulted in a well-designed 6" performance lift kit system that's ready to take on the most challenging off-road terrains.

      Great for All Types of Terrain. The Fabtech 6" Gen II Performance Lift System works both for off-road and city driving. For rough terrain, all bracketry are constructed from ¼" thick steel to provide maximum strength and optimal reliability. There's also a ¼" thick skid plate to protect the front differential. Meanwhile, the kit's relocation of the front differential results in a noticeable reduction in vibration when driving at higher speeds.

      Clean Overall Appearance. The new Gen II system keeps your vehicle's factory track width and 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. Designed for 2WD and 4WD 2014-2018 GMC Sierra models, this 6" Gen II Performance Lift System fits vehicles with a double cab or crew cab. It is not compatible with Denali models with Magnetic Ride Control.

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