The SPC Performance front upper adjustable control arm for Jeep JK is a direct-fit replacement that adds strength and on-vehicle adjustability for stock-height or lifted Wranglers. It features SPC's xAxis sealed flex joints in forged frame rings for bind-free articulation, a dual-threaded adjuster with jam nuts for quick caster/pinion tuning, and a 3/16" wall DOM steel main tube for added durability.
