SPC Performance 86470 Forged Front Upper Control Arms - Select GM 1999-2006 (1500/1500 HD)

Fits select 1999-2006 Cadillac Escalade, Chevrolet Silverado/Tahoe/Suburban/Avalanche, and GMC Sierra/Yukon 1500 and 1500 HD models.

When you lift your GM truck or SUV up to 3" or lower it more than 1", the front suspension loses critical caster, often exceeding the adjustment range of factory cams. These SPC Performance fixed-offset upper control arms provide a +2.0° caster change to restore alignment geometry and improve high-speed stability. For extreme lowering applications (greater than 1"), these arms can be swapped side-to-side to achieve a -2.0° caster change as needed.

Engineered for durability and ride quality, these arms feature a fully forged construction for maximum strength. They are equipped with SPC’s xAxis sealed flex joints, which provide a free pivot for full suspension travel without the binding common in OE joints. Integrated rubber isolation ensures the vehicle retains factory Noise, Vibration, and Harshness (NVH) levels. The kit includes both left and right-hand side arms and features greasable, booted ball joints for a long service life.
