This popular adjustable upper control arm/shim kit has been re-designed to match the SPC family of Nissan and Infiniti arms. Our new tubular design has reduced weight by 1 pound per arm and increased rigidity. SPC’s arms are the only 350Z arms on the market that can get +3.5deg to -1.5deg camber change. Additionally, you will be able to set your caster at +-1.0deg. This patented design makes camber and caster adjustment easy using the sliding and rotating ball joint. The kit includes everything needed, including the ABS sensor bracket, shims, and the adjustable arms. California Residents WARNING

This pair of patent pending adjustable front upper control arms will give +-4deg camber and +-4deg caster change. SPC arms match the OE design for clearance so you can get up to +2deg camber change without fender well interference. If more positive change is needed use the included +2deg camber shims for fixed change and dial in the rest with your arms. The rubber isolated xAxis sealed flex joints retain OE bushing values (Noise, Vibration, and Harshness – NVH), while providing the handling qualities of a mono-ball. Optimized geometry and high strength forged steel components make this the strongest adjustable arm on the market today. Whether you want a cambered stance, improved handling, or to minimize tire wear, this is the best arm for you. US Patent # US 2016/0059652 A1 California Residents WARNING

Designed, engineered, tested, and assembled in Colorado, SPC Performance adjustable upper control arms are loaded with features. Improve suspension travel, handling, and tire wear while centering the tire in the wheel well for maximum clearance needed for oversized tires. Now equipped with maintenance-free ball joints and free-pivoting xAxis™ sealed flex joints in bonded rubber sleeves, for correction of alignment angles and restoration of factory ride quality. A Forged steel design provides the strength and durability needed for the most demanding environments. SPC adjustable control arms have improved clearance to get around the spring bucket and a full 80° of articulation in the ball joint. When trucks are lifted, caster and camber angles are affected that can lead to poor handling characteristics such as ‘wandering’. SPC control arms have positive caster built-in for lifted vehicles to restore alignment angles and drivability. The patented ball joint design allows the tire to be positioned correctly in the wheel well and additional adjustment in the OE lower arms can maximize placement for oversized tires to avoid fender trimming. If replacement lower adjustment cams are needed, see part #86250 or #86252. Sold as pairs. US Patent No. 7,513,514.
