TJ/LJ Johnny Joint Adjustable Control Arm Set
The RockJock® Johnny Joint® Control Arm Set for all Jeep® TJ Wrangler & LJ Unlimited 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 & 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. Arms are fully greasable via zerk fitted Grade 8 hardware. Finish is semi-gloss black powder coat on the arms & front forks and gold zinc plating on the Johnny Joint adjuster ends.

Notes
Upper Arms include CE-91127 Greasable Bolts & Lower Arms include CE-91107 Greasable Bolts. Upper arms are fabricated from 1” x .156” wall D.O.M. steel tubing, lower arms are 1 1/4” x .188.” wall D.O.M. steel tubing. Upper arms feature 3/4"-16 RH threads, lower arms feature 1”-14 RH threads. Installation of the front upper arms may require reaming the front differential housing bushing inner sleeve out to 7/16”. We highly recommend the use of our CE-9102K Front Axle Housing Johnny Joint Kit in conjunction with this arm set. Johnny Joints require non-synthetic, hi-moly lube grease such as our CE-9013G
