Adjustable Upper Control Arm Pair

The Stillen and SPC 25480 Adjustable Upper Control Arms are a high-performance suspension upgrade designed for precise alignment adjustments. Developed through a partnership between STILLEN and SPC Suspension, these arms are manufactured in the USA with a focus on durability and performance. Engineered to address alignment challenges after lifting a vehicle, these control arms provide ±2.0° of camber and 0.0° to +4.0° of caster adjustment. This allows for dialing in your vehicle's alignment angles to restore drivability and tracking. They also help center the tire in the wheel well, maximizing clearance for oversized tires and potentially minimizing fender trimming. Construction features forged steel for strength and durability, greaseable ball joints, and SPC's patented xAxis™ sealed flex joints in bonded rubber sleeves for improved comfort and reduced vibrations. The design offers 80° of articulation in its ball joint for maximum droop travel. Installation time is estimated at 0.8 hours per side. These upper control arms are compatible with the following vehicles: 2003-2021 Toyota 4Runner, 2007-2014 Toyota FJ Cruiser, 2010-2021 Lexus GX460, and 2003-2009 Lexus GX470. Some sources also indicate fitment for 1996-2002 Toyota 4Runner and 1995-2004 Toyota Tacoma, though it is advised to verify specific fitment for these earlier models.
