The factory upper control arms are fixed, so lifting the FJ shifts the ball-joint angle, leading to premature ball-joint wear, poor steering, reduced wheel articulation, and even suspension binding. Generic upper control arms for the FJ are made from low-quali
ty steel, which is heavy and prone to bending—hardly ideal for offroad use.
HPR’s Forged Aluminum Alloy Heavy Duty Adjustable Front Upper Control Arms for Toyota FJ Cruiser are engineered to fix ball-joint angle misalignment and deliver unbeatable offroad performance. Our control arms feature a built-in 3-degree caster that corrects the ball-joint angle when lifting your FJ by 40mm or more, restoring optimal steering, wheel articulation, and suspension performance. Manufactured from high-strength forged aluminum alloy, these control arms are lighter than steel alternatives (reducing unsprung weight) and far more rigid, making them resistant to bending under offroad stress.
As a specialist in Toyota offroad suspension parts, HPR designed these control arms with the FJ Cruiser’s unique offroad needs in mind. Every arm is precision-machined in our in-house facility for a perfect fit, and the adjustable design lets you fine-tune the alignment for your specific lift height. Backed by HPR’s 15+ years of OEM experience, these control arms are a direct, bolt-on upgrade that eliminates premature ball-joint wear and improves your FJ’s offroad handling.
If your lifted FJ Cruiser has poor steering or premature ball-joint wear, contact HPR today to get your forged aluminum upper control arms.
