RockJock's Johnny Joint Control Arm Set for all Jeep JK Wrangler models provides you with extremely heavy duty, adjustable length control arms to replace all 8 of your factory control arms. Adjustable control arms are an absolute must after your lifting your vehicle to get your caster and pinion angles back in check!
Arms feature RockJock’s 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 and are finished in semi-gloss black powder coat.
