SPC xAxis Adjustable Front Upper Control Arm Pair Bronco 21-26

Improve alignment, suspension travel, and tire clearance on your lifted 2021-2026 Bronco with this pair of SPC xAxis Adjustable Front Upper Control Arms. Designed, engineered, tested, and assembled in Colorado, these arms provide the additional alignment correction needed to address caster and camber changes commonly created when lifting a vehicle.

SPC combines chromoly tubing with a billet-machined steel nose for strength and clearance around the spring bucket. Positive caster is built into the arms for lifted applications, while SPC's patented adjustable ball joint works with the factory lower control arm cam adjusters to provide additional alignment flexibility. This configuration can also help move the tire forward in the wheel opening to maximize clearance for larger tires while minimizing the need for frame or fender modifications.

The maintenance-free ball joints feature a stud with a 25-percent larger cross section than the factory design, an E-Nickel coating for corrosion protection, and 80 degrees of articulation. Extended ball joint threads also provide compatibility with knuckle gusset kits. A fully sealed architecture keeps grease in and contaminants out, while a one-piece polymer race and modern grease formulation promote smooth, quiet operation and reduced wear.

SPC's xAxis sealed flex joints use bonded rubber bushings to allow increased suspension travel while maintaining excellent noise, vibration, and harshness characteristics. Together, these features help restore alignment and driveability, improve tire wear, and provide the clearance and articulation needed for modified Broncos.
