    Superior Performance Value. If you enjoy aggressive off-road driving, then the Fabtech 4-Inch Uniball Upper Control Arm System with Dirt Logic Coilover Reservoirs and Shocks is perfect for your GMC Sierra. These uniball upper control arms were designed as an upgrade to Fabtech's popular 4-Inch Budget System. This UCA system provides superior performance value to your truck.

    Dirt Logic Shocks. The Dirt Logic 2.5 front shocks have been designed for off-roading with their desert racing experience. They feature a variety of coilover applications. You'll benefit from superior dampening capabilities that will enhance off-roading. The rear shocks were designed to replace the factory shocks to deliver a stronger configuration. They have been pretuned for the specific Fabtech suspension.

    Durable Skid Plate. Heavy-duty front differential drop brackets are included with this system. The 1/4-inch thick skid plate is extremely durable and able to provide the ultimate in protection from off-road obstacles. 

    High-Caliber Uniball Arms. The uniball control arms have been designed to exhibit unrivaled strength. They have excellent range of motion. The control arm was engineered with 120-inch 4130 Chromoly wall tubing to make sure that it is long-lasting. The 1-inch FK stainless PTFE uniballs have substantial strength. You will benefit from upper control arms that perform well in rough terrain.

    Rear Lift Blocks and Coilovers. The Dirt Logic 2.5 Coilovers provide 10 inches of front wheel travel. You'll have a leveled stance with the 1.5-inch rear lift block and durable U-bolts.

    Installation. To complete the installation of this UCA system some mechanical expertise is required.

    Powertrain Warranty. This UCA system will qualify for the Fabtech 5/60 powertrain warranty. There may be some limitations, so check the warranty for more details.

    Application. The Fabtech 4 inch Uniball Upper Control Arm System with Dirt Logic Coilover Reservoirs and Shock was designed to fit 2007-2013 Extended Cab and Crew Cab GMC Sierra models.
