Description
Lifted Stance. Add a commanding, off-road stance to your 2019-2025 GMC Sierra by upgrading to a Fabtech 3-Inch Uniball Upper Control Arm Lift Kit that includes Dirt Logic 2.5 Coil-Overs and Dirt Logic 2.25 Shocks. With 3.0 inches of lift, this kit can accommodate tires up to 33 x 12.5 in size mounted on 20-inch wheels allowing you to conquer any trail. This Fabtech Lift Kit features tubular upper control arms with uniball bearings, as well as rear lift block spacers. What’s more, the included Dirt Logic 2.5 Coil-Overs and Dirt Logic 2.25 Shocks provide incredible dampening capacity for aggressive off-road driving.
Dirt Logic 2.5 Front Coil-Overs. Fabtech includes Dirt Logic 2.5 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.
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.
Upper Control Arms. This Fabtech Lift Kit includes a set of tubular Upper Control Arms equipped with high quality 1-inch FK stainless PTFE lined Uniball bearings for improved directional stability and better handling. The super stout Upper Control Arms are constructed from .120-inch wall, 1.50-inch OD 4130 Chromoly tubing making them ideal for rugged off-road conditions.
Rear Lift Blocks. Rear lift is obtained with the use of 1.5-inch blocks and u bolts. These lift blocks are cast from iron steel for superior strength. The included u bolts and fasteners allow for a straight forward installation.
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 4 hours time.
Application. This Fabtech 3-Inch Uniball Upper Control Arm Lift Kit with Dirt Logic 2.5 Coil-Overs and Dirt Logic 2.25 Shocks is designed to fit 2019-2025 GMC Sierra 1500 Double Cab and Crew Cab, excludes standard cab, AT4, Denali and Diesel models.
