The RockJock Johnny Joint Double Adjustable Rear Upper Control Arm Set for all TJ Wrangler and LJ 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 1 in. o.d. x .156 in. wall D.O.M. steel bodies and adjustable 2 in. Johnny Joints on both ends.
Johnny Joints, the original and most durable high-articulation urethane suspension joint on the market, 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. 
Arms are fully greasable via zerk fitted Grade 8 bolts. Finish is semi-gloss black powder coat on the bodies & forks and gold zinc plating on the Johnny Joint adjuster ends.
