For 2005–2023 Toyota Tacoma (2WD / 4WD)

Built to Solve Real Problems. Designed to Perform Everywhere.

If you drive a 2005–2023 Tacoma and are ready to upgrade your suspension, the Dirt King 4130 Upper Control Arms are built for you. Designed to fix the common issues that plague lifted Tacomas — squeaky bushings, high-maintenance joints, and poor geometry — these UCAs deliver rock-solid reliability whether you’re overlanding, daily driving, or hitting desert trails.

Made from precision-welded 4130 chromoly tubing, these arms feature maintenance-free SilentSpin™ hybrid bushings that eliminate grease fittings and noise. Heavy-duty Probearing Pro 4 ball joints offer 76° of articulation, sealed protection from debris, and long-term durability. Engineered to maintain perfect alignment through 0–3" of lift, they also add about one inch of extra down travel when paired with Dirt King, King, Fox, Icon, or other performance coilovers.
