SPC Performance’s adjustable upper control arms are filled with features and designed, built, tested, and produced in Colorado. To optimize room for your bigger tyres, centre your tyre in the wheel well to improve suspension travel, handling, and tyre wear. This arm will correct alignment angles and restore factory ride quality thanks to greaseable ball joints and xAxisTM sealed flex joints in bonded rubber sleeves. For the most demanding conditions, SPC’s forged steel construction delivers the strength and durability required. (Sold in pairs.)
- Get the most suspension travel available: SPC’s arms have additional room around the spring bucket and an 80-degree rotating ball joint. The xAxis joints on SPC’s arm are now free pivoting, allowing for maximum droop mobility. More travel than any mono ball or ball joint arm currently available.
- Get your tracking and drivability back: Lifting your truck changes the caster and camber. SPC’s arms have +2 degrees of caster built-in. The arm will provide you 0° to +4° of caster and 2° of camber thanks to its innovative ball joint design. This flexibility allows you to return your alignment angles to their original settings.
- Get your tire where you want it in the wheel well: To minimize or prevent fender trimming, adjust the control arm and OE lower cams to improve alignment angles and slide big tyres forward in the wheel well.
Adjustment range: Camber ±2.0°
Caster 0.0° to +4.0°
