Improve droop travel, drivability and tire wear as well as adjusting tire position in your wheel well with SPC's adjustable front upper control arms for the Frontier, Pathfinder, and Xterra. Featuring our long life maintainable ball joint and SpecRide bushings, this arm is designed to correct alignment angles while maintaining factory ride quality. SPC's integrated tubular and cast steel design provides the strength and durability needed for the most demanding environments. These remove and replace arms are available in pairs for lifted and off-road applications.

Get more droop travel: SPC's arm has improved clearance to get around the spring bucket when the arm droops, eliminating arm to frame contact on lifted trucks. The maintainable ball joint has an oversized ball and allows more than 80° of articulation to ensure it never binds. SpecRide bushings have free pivot to eliminate any chance of bushing failure seen on many high travel suspensions.

Get your drivability and tracking back: When you lift your truck you affect caster and camber. SPC's arms have +1° of caster built into them. Using its patented ball joint design the arm will get you -1° to +3° of caster and ±2° of camber.

Get your tire where you want it in the wheel well: Use adjustment in the control arm and on the OE lower cams to maximize alignment angles and move oversized tires forward in the wheel well to minimize or avoid fender trimming.

To make installation easier, SPC now includes a bolt to replace the driver's side rearward bolt, which often needs to be cut out to remove the original arm. If you need more bolts for the other positions order p/n 21035 replacement bolt kit (2 bolts).

Do you need replacement cams for the lower control arm? Check out SPC p/n 87520, which will replace corroded cam bolt assemblies, or can be used on trucks not equipped with factory cam bolts for the lower control arm. These cams should be used with the upper arm kit to maximize your set-up.

* On the adjustable ball joint SPC uses hex chromate free finish and offers a 700hr salt spray test for the best corrosion protection available.
