Fabtech 2020 GM 2500HD/3500HD 4WD 6in Lift System - Uniball UCA Kit

Starting with the 1.25-inch OD, .120 wall thick chromoly tubing, this Fabtech Uniball Upper Control Arm kit is built to handle the demands of off-road driving. These arms are designed to replace your factory upper ball joint arms, significantly strengthening the front suspension of your 2020-2023 Chevrolet Silverado 2500 HD or 3500 HD, or your 2022-2023 GMC Sierra 2500 HD or 3500 HD. The 1-inch diameter stainless steel Uniballs are a direct replacement for the stock ball joints and attach to the factory spindle without any drilling required, making installation more straightforward.

This kit is a key component for those looking to enhance their vehicle's suspension for more aggressive off-road use. The Uniball design offers improved strength and better alignability compared to the factory ball joint setup. These arms are engineered to work seamlessly with your stock suspension components or can be integrated as part of Fabtech's 2-inch or 6-inch lift systems. The use of 17-4 stainless steel for the Uniball pin, which is heat-treated, further contributes to the overall durability and performance of the system.

When you're planning a lift for your heavy-duty truck, especially for off-road adventures, strengthening the upper control arms is a critical step. This Fabtech kit provides that necessary reinforcement, ensuring your suspension can withstand tougher conditions. It's a well-built upgrade that directly addresses the limitations of the stock components for more demanding applications.
