Description
Lifted Stance. Add a commanding, lifted off-road stance to your 2019-2025 AT4 Sierra by upgrading to a Fabtech 4-Inch Performance Suspension Lift Kit that includes Dirt Logic 2.5 Reservoir Coil-Overs and Dirt Logic 2.25 Shocks. With 4.0 inches of lift, this kit can accommodate tires up to 35 x 12.5 in size mounted on 20-inch wheels allowing you to conquer any trail. This Fabtech Performance Lift Kit features extended length steering knuckles as well as lift blocks, front differential skid plate and lower control arm crossmembers. What’s more, the included Dirt Logic 2.5 Reservoir Coil-Overs and Dirt Logic 2.25 Shocks provide incredible dampening capacity for aggressive off-road driving.
Dirt Logic 2.5 Reservoir Front Coil-Overs. Fabtech includes Dirt Logic 2.5 Reservoir Front Coil-Overs in this kit to ensure controlled dynamics with improved handling. These Coil-Overs have 2.5-inch OD stainless steel bodies with a 2.25-inch OD billet aluminum piston and 7/8-inch NitroSteel® black piston rods. With an adjustable Coil-over construction, these Coil-Overs feature cold wound coil springs and 5/8-inch spherical ball mounting ends. Additionally, these Coil-overs feature a 2.50-inch OD aluminum reservoir with -8 stainless steel O-ring hose.
Dirt Logic 2.25 Rear Shocks. Fabtech Dirt Logic 2.25 Rear Shocks ensure a superior ride, both on and off road. These Rear Shocks have 2.25-inch OD stainless steel bodies with a 2.0-inch OD billet aluminum piston and 7/8-inch NitroSteel® black piston rods. These Shocks are specifically pre-tuned for Fabtech suspensions, accounting for larger tires, providing the finest all around damping.
Iron Steering Knuckles. Fabtech includes a set of heavy duty, extended length steering knuckles in their 4-inch Performance Suspension Lift Kit. These steering knuckles are manufactured from ductile iron for superior strength. The knuckles have a near stock track width that keeps your tires under the fenders for a clean appearance.
Rear Lift Blocks. Rear lift is accomplished by removing the factory blocks and replacing them with the included 5-inch lift blocks and u-bolts. The included u bolts and fasteners allow for a straight forward installation. These lift blocks are cast from iron steel for superior strength.
Skid Plate and Crossmembers. Both the front differential skid plate and lower control arm crossmembers are constructed from 1/4-inch thick steel plate for superior strength. The skid plate will protect the front differential from rocks and obstacles, while the lower control arm crossmembers will provide additional strength to the front suspension. The crossmembers retains factory alignment cams for easy adjustment.
No Welding Required. Fabtech engineered their Lift Kit to be installed with no welding needed, making it a bolt-on kit. However, it should be noted that professional installation is recommended. With all the necessary hardware included, this Lift kit can be installed in about 6 hours time.
Application. This Fabtech 4-Inch Performance Suspension Lift Kit with Dirt Logic 2.5 Reservoir Coil-Overs and Dirt Logic 2.25 Shocks is designed to fit 2019-2025 Sierra 1500 AT4 4WD models, excluding diesel.
Technical Note. Will not fit models equipped with adaptive ride control. Not for use with OEM wheels and tires.
