Fabtech 07-18 GM C/K1500 w/OE Forged UCA 0-6in Uniball Upper Control Arm Kit

Fabtech’s Uniball Upper Control Arms for the specified vehicles are engineered to fit 0–6″ lift systems. They are designed to increase front suspension strength by replacing factory upper arms and ball joints, which can weaken or fail under aggressive off-road use. These heavy-duty arms are built for long-term performance in rugged conditions and include additional caster for improved on-road handling and alignment when using oversized tires. They are crafted from .120" wall, 1.50" OD 4130 Chromoly tubing for reduced flex, leading to a more responsive and stable driving experience. The arms feature 1" FK Stainless PTFE-lined Uniballs for exceptional articulation and durability. The heat-treated 17-4 Stainless Steel Uniball pins fit directly into the factory ball joint taper without spindle modification, allowing for quick installation and the ability to return the vehicle to stock. Fabtech also integrates 17-4 Stainless Steel misalignments to ensure proper clearance of the 1" Uniballs throughout the full suspension travel range. High-quality urethane bushings on the frame side minimize road noise and provide excellent longevity.
