RockJock TJ/LJ Johnny Joint Adjustable Control Arms Lower Front or Rear Adjustable Greasable Pair

The RockJock Johnny Joint adjustable control arms are high-performance suspension components designed for TJ Wrangler, LJ Unlimited, XJ Cherokee, MJ Comanche, and ZJ Grand Cherokee vehicles. Constructed from 1 inch by 0.156 inch wall DOM tubing, these arms feature Johnny Joint rod ends at both ends to provide maximum articulation and durability. The arms are powder coated in semi-gloss black for corrosion resistance and include zerk-fitted grade 8 mounting bolts for easy lubrication and secure installation. Their primary function is to allow precise pinion angle adjustments after a suspension lift, ensuring optimal driveline alignment and handling. The adjustable design also enables upgrading to different lift heights without replacing control arms, offering versatility and long-term value for off-road and performance applications.

These control arms are suitable for a wide range of vehicles, including TJ Wranglers, LJ Unlimiteds, and all years of XJ Cherokee, MJ Comanche, and ZJ Grand Cherokee. They are intended for use in off-road, lifted, or performance setups where suspension geometry adjustment is critical. Installation involves bolt-on replacement of existing control arms, making them a direct upgrade for vehicles with suspension lifts. The kit includes the control arms with Johnny Joints and mounting hardware, providing a robust solution for maintaining proper alignment and articulation under demanding conditions. These arms are ideal for off-road enthusiasts and those seeking adjustable, durable suspension components for improved vehicle performance.
