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. Featuring an upgraded greasable ball joint and rubber isolated xAxis bushings, this arm is designed to correct alignment angles while maintaining factory ride quality. SPC's fully forged steel design provides the strength and durability needed for the most demanding environments. These remove and replace arms are sold in pairs. Get more droop travel: SPC's arm has improved clearance to get around the spring bucket. With 80° of articulation in the upgraded ball joint and free pivoting cross axis bushings, SPC's arm gives you maximum droop travel. Get your drivability and tracking back: When you lift your truck you affect caster and camber. SPC's patented ball joint design will get you ±2° of caster and ±2° of camber, beyond what the truck's lower slots provide, so you can put your alinment angles back to specification. Get your tire where you want it in the wheel well: Use adjustment in the SPC arm and on the OE lower arm to maximize alignment angles and move oversized tires forward in the wheel well to minimize or avoid fender trimming. Also consider SPC #86252 with upgraded bolts and adjustment plates to lock in your alignment and prevent bolt slip on the lower control arm.
