Description
Exceptional Rough Terrain Performance. Beat the rough terrain and the competition with this Fabtech 6-Inch Performance Suspension Lift Kit with Dirt Logic 2.5 Reservoir Coil-Overs and Dirt Logic 2.25 Shocks on your GMC Sierra 1500 truck. Outfitting your truck with this lift kit increases its height by 6 inches and allows you to install up to 35-inch tires without compromising its performance. And with the combination of powerful front and rear shocks, steering knuckles, and crossmembers, this lift kit allows your truck to conquer more easily even the most challenging off-road driving conditions.
Powerful Front and Rear Shocks. For exceptional performance, this suspension lift kit features 2 front Dirt Logic 2.5 shocks with coil-overs and reservoir. They provide excellent damping capability with their adjustable coil-overs, NitroSteel black piston rods, and nitrogen gas reservoir. Meanwhile, the rear Dirt Logic 2.25 shocks included in this kit replaces the factory rear shocks to provide better shock damping capability, so you can experience smoother handling on rough roads, even at high speeds.
Durable Steering Knuckles. This suspension lift kit comes with Fabtech’s extended length ductile iron Steering Knuckles. They improve handling by eliminating bump steer throughout the suspension travel. Meanwhile, their heavy-duty steel construction adds to the overall strength of the entire suspension system.
Sturdy Control Arm Crossmembers. This kit also comes with 0.25-inch thick steel lower control arm crossmembers. They have been engineered to provide maximum ground clearance with their arched design. These crossmembers have also been welded for maximum front suspension strength while maintaining factory alignment cams.
High-Quality Bump Stop Spacers and Lift Blocks. For maximum suspension efficiency, this lift kit comes with high-quality bump stop spacers and lift blocks. They have been specially designed for perfect fit and to ensure excellent rigidity and ride quality.
Straightforward Installation. The installation of this suspension lift kit requires mechanical expertise. Most parts install using your truck’s factory mounting locations, but some cutting is required.
Backed by a 5-Year Warranty. For quality assurance, Fabtech backs this suspension lift kit with a 5-year/60,000-mile Powertrain warranty against manufacturing defects from the date of purchase. Some limitations apply. For more information, please refer to the manufacturer’s website.
Application. This Fabtech 6-Inch Performance Suspension Lift Kit with Dirt Logic 2.5 Reservoir Coil-Overs and Dirt Logic 2.25 Shocks fits all 2020-2025 GMC Sierra 1500 4WD 3.0L Crew Cabs with Short Boxes, Excluding AT4 and Denali Models.
