Serious Articulation for Custom Suspension Links
The RockJock CE-9110NP-14 is a narrow-style Johnny Joint rod end sized at 2 1/2 inches outer diameter, with a 2.365 inch mounting width and a .562 inch thru-bolt hole. Built for fabricators and suspension builders, it offers up to 40 degrees of articulation, well beyond what a common heim joint can provide, while its urethane-cushioned internals absorb harshness that a standard heim joint transmits directly into the chassis.
Key Features
- Up to 40 degrees of articulation in a narrow-body design.
- High-density urethane bushings cushion the inner ball for a smoother ride than a metal-on-metal heim joint.
- Cross-drilled, heat-treated center ball for thru-bolt lubrication.
- Weldable .180 inch wall DOM tubing outer shell.
- External zerk fitting for easy greasing after installation.

FAQ
How much articulation does this rod end allow?
Up to 40 degrees of movement in any direction.
How does this compare to a standard heim joint?
A common heim joint typically allows around 22 degrees of movement, while this narrow Johnny Joint allows up to 40 degrees along with urethane cushioning that a heim joint does not have.
Is this rod end weldable?
Yes, the outer shell is .180 inch wall DOM tubing designed to be welded into a custom link or control arm.
What is the thru-bolt hole size?
.562 inch.
How is this rod end greased?
Externally, through an installed zerk fitting on the joint body.
Does this ship assembled or disassembled?
It ships assembled and ready to weld into place.
What is the mounting width of this joint?
2.365 inches.
Is this the narrow or standard body style?
This is the narrow body style, which allows greater articulation than the standard width version.
Installation Instructions
- Determine the correct link length and cut the link tubing to size, leaving room for the rod end to be welded in.
- Clean and prep the tubing end and the rod end shell for welding.
- Insert the rod end into the tubing and tack weld it in the correct orientation, checking alignment before final welding.
- Complete the weld around the full circumference of the joint per good welding practice for suspension components.
- Allow the weld to cool fully, then grease the joint through the zerk fitting before installation on the vehicle.
- Install the completed link using the correct thru-bolt hardware, and torque to the vehicle or fabrication specification.
