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 as much suspension travel as possible: SPC’s arms feature more space around the spring bucket and a ball joint with 80 degrees of mobility. SPC’s arm now has free pivoting xAxis joints, allowing for maximum droop movement. There is more travel in this arm than in any other ball joint or mono ball-equipped arm on the market.
- 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°
