SPC Performance Toyota Tacoma/4Runer / Lexus LC250 & GX550 Adjustable Upper Control Arm (Pair)

Designed, engineered, tested, and assembled in Colorado, SPC Performance adjustable upper control arms are loaded with features. Improve suspension travel, handling, and tire wear while centering the tire in the wheel well for maximum clearance needed for oversized tires. Now equipped with maintenance-free ball joints and free-pivoting xAxis™ sealed flex joints in bonded rubber sleeves, for correction of alignment angles and restoration of factory ride quality. A light-weight, forged aluminum design provides the strength and durability needed for the most demanding environments. SPC adjustable control arms have improved clearance to get around the spring bucket and a full 80° of articulation in the ball joint. When trucks are lifted, caster and camber angles are affected that can lead to poor handling characteristics such as ‘wandering’. SPC control arms have positive caster built-in for lifted vehicles to restore alignmen t angles and driveability. The patented ball joint design allows the tire to be positioned correctly in the wheel well and additional adjustment in the OE lower arms can maximize placement for oversized tires to avoid fender trimming. If replacement lower adjustment cams are needed, see part #25415. Sold as pairs. US Patent No. 7,513,514. Adjustable front upper control arms for the Toyota Tacoma, 4Runner, LC250, and Lexus GX550 with forged aluminium construction, sealed modern architecture ball joints, and xAxis™ sealed flex joint joints in bonded rubber bushings Product appearance and features may vary in the market as design changes, improvements and modifications are implemented.

• Sold as a pair

Designed, engineered, tested, and assembled in Colorado, SPC Performance's adjustable upper control arms are crafted for optimal suspension performance. Constructed from forged aluminum, these control arms deliver strength and durability while reducing overall weight for demanding off-road and street applications. They improve suspension travel, handling, and tire wear by ensuring the tire stays centered within the wheel well, providing maximum clearance for oversized tires without the need for frame or fender modifications. The arms feature adjustable components that allow precise alignment corrections, including positive caster built-in for lifted vehicles to restore proper handling characteristics and reduce wandering. The innovative design includes maintenance-free, sealed modern architecture ball joints with a larger stud cross section for enhanced strength and corrosion resistance, along with bonded rubber xAxis™ flex joints that extend suspension travel and improve noise, vibration, and harshness (NVH) performance. These components are engineered to accommodate a full 80° of articulation, ensuring reliable operation even in extreme conditions, and are compatible with a variety of models including the 2024 Lexus GX550 and Toyota Tacoma. The full set is sold as pairs, making installation straightforward and ensuring balanced suspension performance. The control arms' design also includes additional adjustment in the OE lower arms, maximizing tire placement and further reducing the need for fender trimming. With built-in caster adjustment, these control arms help maintain optimal alignment angles after lifting, leading to improved drivability, reduced tire wear, and enhanced handling. The durable construction and sealed joints mean less maintenance over time, making them an excellent choice for enthusiasts seeking reliable, high-performance suspension upgrades. For replacement lower adjustment cams, see part #25415. These control arms are covered by a US patent and are a reliable solution for improving your vehicle's suspension geometry and performance.
