RockJock's Johnny Joint Rear Upper Control Arm Set for all JL and JK Wrangler and Unlimited models provides you with extremely heavy duty, adjustable length control arms to replace your factory control arms. Adjustable arms are a must for aligning lifted vehicles to get your pinion angle specs. in check!
These arms feature RockJock’s 2 1/2 in. Johnny Joints, the original and most durable high-articulation urethane suspension joint on the market. Johnny Joints feature a smooth steel ball that pivots inside a proprietary urethane shell to provide over 30 degrees (per joint) of quiet, shock dampening articulation - without the excessive deflection found in soft rubber-based flex joints. Johnny Joints deliver a smooth, comfortable on-road ride with the ultimate in off-road capability. They are so trusted, that they are used by multiple commercial suspension companies, for both street and off-road suspension systems. Learn more here.
Arms are fully greasable via zerk fittings. Finish is semi-gloss black powder coat on the arms and gold zinc plating on the Johnny Joint adjuster ends.
