RockJock’s Johnny Joint Rod Ends have been a staple in the off road industry since 1996! Available universally for builders or found in our RockJock suspension components, John Currie’s proven formula provides a reliable, greasable, rebuildable joint that is capable of dramatic articulation in off-road applications, while still providing smooth, cushioned, quiet performance during on-road use.
Johnny Joints are available as a forged rod end with various RH and LH thread sizes from 3/4 in. up to a massive 1 1/2 in. thread! Additionally, weld-on versions of all Johnny Joints are available for fabricators.
Specialty joints, such as polished stainless steel, long body and bent forgings and application specific machined joints are all available for custom builder use.
All sizes of joints offer a standard or a narrow width joint body which provide different levels of overall articulation range (up to 30 plus degrees on a standard body and up to 40 plus degrees on a narrow body). The narrow body’s 1 piece bushing will provide a slightly firmer ride.

This 2 in. Johnny Joint incorporates our machined, press-in, standard width, steel outer barrel and a 2 in. overall width x .515 in. thru-bolt hole pivot ball.
The machining to the outer barrel allows it to be pressed in to the front differential casting on JK/TJ/LJ/XJ/MJ/ZJ vehicles to replace the factory rubber bushing.
Greasing is handled internally via the included CE-91128 greasable bolt.

• *** IMPORTANT *** – joints require greasing at normal intervals, but they do not hold a lot of grease! Over greasing can cause damage to the joint. To prevent damage, use only a hand pump grease gun, do not expect the joint to take a lot of grease and DO NOT use pneumatic or electric grease guns!
