RockJock’s forged Johnny Joints for fabricators and suspension system builders offer 30 degrees of unrestricted movement in any direction as compared to 22 degrees on a common heim joint! Johnny Joint rod ends offer cushioning that a heim joint cannot provide via high-density urethane bushings that encase the inner ball. The heat treated center balls are cross-drilled for thru-bolt lubrication and the joint internals are retained with 2 heavy duty, heat treated side washers and a snap ring. This specific joint is a 2 1/2 in. diameter, fitted with a zerk fitting for greasing, 2 1/4 in. of 1 1/4 in.-12 left hand threads on the shank, and a 2.590 in. mounting width ball with a .718 in. thru bolt hole. Finished in gold zinc plating.

Our product lines are designed to offer the absolute most value for your budget. Not every build is the same and we understand that. Our series differ mostly in the components used in the construction of the parts. Our Cruise and Town Series utilizes our high grade flex poly bushings at both ends of the arm, this has proven to be a smooth riding easy to maintain and replace bushing that we absolutely love. Our Camp and Trail Series utilizes 5/16″ wall DOM tubing and incorporates a flexible Johnny Joint at the adjusting end, this series has been our most popular series for all around use, great for daily drivers that want to tear up the trails as well. Our Crawl, Tow, and Track Series utilizes the same 5/16″ wall DOM tubing, but features Johnny Joints at both ends. This series gives you the absolute most out of your suspension. This is great for heavy towing/hauling and extreme off-roading. Also, if the component is straight in these series we will machine these left and right hand threaded for easy adjustment on the vehicle!
We are constantly expanding our product lines to include complete kits, if you don’t see something on the site for your vehicle, reach out to our sales team and we can put something together for you.
Our two main sizes of jam nuts require an1-1/2″ wrench or an 1-5/8″ wrench. Generally speaking the 1-5/8″ jam nuts are used on our lower control arms and the 1-1/2″ jam nuts on our upper control arms and track bars. There are some exceptions, but we do offer a crow’s foot that has both sizes.
Any non-synthetic moly based grease is safe on our products, avoid lithium greases and anything red as this can prematurely deteriorate the internal components of the Johnny Joints and bushings used on our parts.
