SPC 81378 Adjustable Upper Control Arm Kits let you overcome the inability to adjust camber or caster on the factory suspension. These arms directly replace the factory fixed length arms, allowing the camber and caster to be precisely adjusted during an alignment. Engineered for the street and track, the forged 6061-T6 aluminum ends with 18mm threaded adjuster links assure this is the strongest kit available. Maintenance free ball joints and xAxis sealed flex joints reduce compliance vs rubber bushings for less deflection and better feedback. The xAxis joint is similar to a heim joint however the xAxis joints are far superior for street use as they are sealed to keep grease in and contaminants out.

SPC Upper Control Arm Adjustability:
The SPC Adjustable Upper Control Arm Kit will allow ±1.5° camber or caster change. We recommend a setting of 1.5° or higher, if the arms are adjusted to longer lengths (for 1.4° or less camber) there may be some contact from the end of the arm to the fender body seam.

The SPC Adjustable Upper Control Arm Kit is made from forged 6061-T6 aluminum with 18mm threaded adjuster links and maintenance free balljoints and xAxis inner joints.

SPC Upper Control Arm Install:
Professional installation recommended, the vehicle will need to be aligned immediately after install.
