      Description

      Built for Competitive Off-Road Driving. The Fabtech 4-Inch Performance Suspension Lift Kit with Dirt Logic 2.5 Coil-Overs and Dirt Logic 2.25 Shocks gears up your truck for competitive off-road driving. This lift kit accommodates up to 35-inch tires and raises your truck’s clearance to make it more agile on the trails. Without a doubt, this suspension lift kit has all the components needed to help your Duramax Sierra 1500 AT4 truck traverse rugged terrain with ease, even at high speeds.

      Race-Ready Front and Rear Shocks. This suspension lift kit readies your truck for the competition with 2 front Dirt Logic 2.5 shocks with cold-wound coil-over springs, NitroSteel black piston rods, and spherical ball mounting ends. Meanwhile, the rear Dirt Logic Resi 2.25 shocks included in this kit feature a more robust design with aluminum reservoirs that offer better shock damping than factory shocks.

      High-Performance Steering Knuckles. The extended-length ductile iron steering knuckles included in this lift kit are designed to eliminate bump steer throughout the suspension travel. This gives you smoother handling on bumpy roads. These knuckles are made of steel to make your suspension system sturdier.

      Rigid Steel Control Arm Crossmembers. This lift kit outfits your truck with lower control arm crossmembers that are made from 0.25-inch thick steel to ensure lasting strength. These crossmembers also come with an arched design that increases your truck's ground clearance for improved off-road drivability.

      Tough Bump Stop Spacers and Lift Blocks. This lift kit includes fabricated bump stop spacers and lift blocks. Each is made from highly durable steel to ensure lasting strength and is designed according to your Duramax Sierra 1500 AT4's specifications to ensure a perfect fit.

      Designed for Simple Installation. This suspension lift kit is designed for simple installation but setting it up requires mechanical expertise. Most parts are installed using factory mounting locations, but some cutting is required.

      Worry-Free 5-Year Warranty. Fabtech covers this suspension lift kit with a 5-year 60,000-mile Powertrain warranty against manufacturing defects from the date of purchase by the original owner. Some limitations apply. Please contact customer service for details.

      Application. This Fabtech 4-Inch Performance Suspension Lift Kit with Dirt Logic 2.5 Coil-Overs and Dirt Logic 2.25 Shocks fits all 2019-2025 3.0L Duramax Sierra 1500 AT4 Models.
