Construction & Design:

Fabtech’s Uniball UCA System is crafted from premium chromoly steel tubing with a 1.25-inch outer diameter and a robust .120-inch wall thickness, ensuring superior strength and resistance to bending or fatigue. The use of stainless steel uniball bearings provides corrosion resistance and smooth articulation, critical for maintaining suspension performance in demanding off-road environments.

The tubular design reduces unsprung weight while maintaining rigidity, contributing to improved suspension response and vehicle control. The system’s bolt-on installation preserves factory spindle integrity by eliminating the need for drilling, simplifying installation and maintaining structural reliability.

Installation & Fitment:

This Uniball UCA System is designed for straightforward installation on 2019 to 2021 Ram 1500 models, including Big Horn, HFE, Laramie, Laramie Longhorn, Limited, Lone Star, Rebel, Special Service, and Tradesman trims. The bolt-on design requires no spindle modifications, making it a direct replacement for factory upper control arms.

Installation is best performed by experienced technicians or knowledgeable enthusiasts with proper tools. The system is engineered to work in harmony with Fabtech Dirt Logic coilover shocks, which are recommended for optimal suspension performance and tuning.

What's Included:

• Pair of 3-inch lift tubular upper control arms with chromoly construction
