Dial in caster and camber on your lifted or leveled truck with the SPC Performance Adjustable Front Upper Control Arm and Ball Joint Assembly (MPN 35685). These forged steel upper arms drop in as adjustable replacements for the 2021-2025 Ford F-150 and 2022-2025 Ford F-150 Lightning, and are designed, engineered, tested, and assembled in Colorado. Sold as a pair; 1 assembly per axle. Covered by US Patent No. 7,513,514.
Forged steel construction: provides strength and added clearance around the spring bucket, with positive caster built in for lifted vehicles.
Fully sealed maintenance-free ball joint: a one-piece polymer race with a 25% larger stud cross section than OE and E-Nickel coating for corrosion protection, delivering 80° of articulation while keeping grease in and contaminants out.
xAxis™ sealed flex joints: free-pivoting joints in bonded rubber bushings for extended suspension travel and improved noise, vibration, and harshness (NVH) characteristics.
Adjustable alignment: Front adjustment range of Camber ±2.0° and Caster 0° to +4.0°; combined with the OE lower adjusters, it helps correct alignment angles and position the tire for added clearance. If replacement lower adjustment cams are needed, see part #86250 or #86252.
