The Fabtech K1129M Uniball Upper Control Arm (UCA) system is engineered specifically for the 2019-2022 GM C/K1500 pickup trucks, including the Chevrolet Silverado 1500 and GMC Sierra. This system provides a ride height increase of 3.5 inches over stock, enhancing off-road capability while maintaining a smooth on-road experience.
The Uniball UCAs are built from .120" wall, 1.50" OD 4130 Chromoly tubing, ensuring durability and strength in demanding conditions. Instead of traditional ball joints, this system utilizes high-quality 1" FK Stainless PTFE lined Uniball bearings, which offer improved articulation and longevity, especially in off-road scenarios.
The rear lift is achieved through the inclusion of 1.5" blocks and u-bolts, paired with Fabtech's Stealth shocks. This setup not only increases ground clearance but also allows for the restoration of the suspension to stock settings when needed.
With this lift system, you can fit larger tires without clearance issues. Recommended tire sizes include:
This system is designed for straightforward installation. However, it is important to note that it is not compatible with OEM wheels and tires, standard cab models, or vehicles equipped with adaptive ride control. Additionally, it does not fit GMC AT4 or Chevy Trail Boss models, nor the 2019 Chevy Silverado LD or 2019 GMC Sierra Limited 1500 models; for these vehicles, refer to the 2018 model application.
