Fabtech’ Uniball Upper Control Arms for the 2006–09 Toyota FJ 2WD/4WD—compatible with 0–6" lift systems—are engineered to significantly increase suspension strength by replacing the factory upper arms and ball joints, which can wear out or fail under aggressive off-road use. These heavy duty arms are built for long-term durability in rugged terrain and feature additional caster compared to stock arms, improving on-road handling and alignment accuracy when running oversized tires.
Premium construction is at the core of this design. Each arm is built using .120" wall, 1.250" OD 4130 Chromoly tubing for superior strength and reduced flex, paired with 1" FK Stainless PTFE-lined Uniballs for exceptional articulation and reliability. The heat-treated 17-4 Stainless Steel Uniball pins fit directly into the factory ball joint tapers without requiring spindle modification, allowing the vehicle to be returned to stock effortlessly if needed.
Fabtech also incorporates 17-4 Stainless Steel misalignments to ensure proper clearance for the large 1" Uniballs throughout the suspension travel range. Quality urethane bushings on the frame side help minimize road noise while providing excellent longevity. These Uniball Upper Control Arms are an outstanding upgrade for both stock and lifted suspension systems, ideal for drivers seeking maximum performance, strength, and precision.
