Factory upper control arms wear out, restrict ball joint articulation, and rely on welded construction that introduces potential weak points over time. Rough Country's forged upper control arms replace the stock units on 2004-2020 4WD F-150 trucks with a one-piece forged aluminum design that eliminates weld seams entirely, delivering superior strength for both daily driving and off-road use at stock ride height.
Forged aluminum, one-piece construction. Forging shapes the aluminum under extreme pressure rather than casting or welding separate sections together. The result is a denser grain structure throughout the arm with no heat-affected zones or weld joints that can crack under load. This construction method outperforms fabricated or cast alternatives in both strength and long-term fatigue resistance.
POM ball joints for extended range of motion. Each arm ships with a Polyoxymethylene ball race that reduces friction significantly compared to standard ball joint materials. The larger ball diameter increases articulation beyond what OEM and conventional replacement joints allow, translating to better wheel travel on uneven terrain. The maintenance-free race design resists wear, and each ball joint includes grease fittings so you can service them before installation and as needed afterward.
OEM-style rubber bushings for reliable street manners. Rubber bushings cushion NVH and keep the control arm compliant over road imperfections, preserving the ride quality you expect from a daily-driven truck. The bushing spec mirrors OEM dimensions for a direct, rattle-free fit.
