Build controlled articulation into a custom link
RockJock CE-9110P-20 combines a weldable steel barrel with serviceable urethane internals and an externally greased pivot ball. Its exact width and bore let a fabricator design the surrounding brackets and link geometry around a known joint envelope.
Key Features
- Standard-width 2.5-inch weld-on Johnny Joint configuration
- 23 degrees of manufacturer-specified articulation
- Serviceable two-piece urethane bushing internals
- Externally greased through an included 1/4-inch-28 zerk fitting
- Weldable steel outer barrel for custom fabrication
- Ships disassembled and ready for welding
Fitment

FAQ
What is the CE-9110P-20?It is a weld-on, standard-width 2.5-inch Johnny Joint assembly for custom suspension and linkage fabrication.
Does this rod end have vehicle-specific fitment?No. It is a universal fabrication component that must be selected by dimensions, articulation needs, mounting design, and structural requirements.
What are the pivot-ball dimensions?The pivot ball is 2.590 inches wide with a 0.718-inch through-bore.
What are the outer barrel dimensions?RockJock specifies a 2.5-inch outside diameter and a 2-inch-wide weldable steel barrel.
How much articulation does the joint provide?RockJock specifies 23 degrees of articulation for this exact configuration.
Is the joint supplied assembled?No. It ships disassembled and ready for a qualified fabricator to weld and assemble for the engineered application.
How is the joint lubricated?An included 1/4-inch-28 zerk fitting provides external greasing through the threaded barrel port.
Which grease and grease gun should be used?Use non-synthetic high-moly grease and a hand-pump grease gun; powered grease guns can over-pressurize and damage the joint.
Which assembly tool applies?RockJock identifies the CE-9110T tool for assembly and disassembly of this Johnny Joint size.
Installation Instructions
- Confirm that the engineered application requires the exact 2.590-inch pivot-ball width, 0.718-inch through-bore, barrel dimensions, and articulation range.
- Verify the package label and manufacturer part number CE-9110P-20 before fabrication begins.
- Have a qualified designer establish bracket spacing, link geometry, material grade, wall thickness, joint orientation, fastener specification, clearances, and expected loads.
- Remove the serviceable internals before welding so heat does not damage the urethane bushings, pivot ball, retaining parts, or grease fitting.
- Prepare and weld the steel outer barrel using a qualified procedure appropriate to the selected link material and structural application.
- Allow the welded assembly to cool naturally, then inspect the weld, barrel roundness, retaining groove, and grease passage before reassembly.
- Lubricate and assemble the pivot ball, bushings, washers, and snap ring with the applicable RockJock tool, confirming complete snap-ring engagement.
- Install the fabricated link with application-engineered hardware, torque it to the design specification, and verify clearance and articulation through the full operating range.
- Lubricate only with non-synthetic high-moly grease and a hand-pump grease gun; stop before excess pressure can damage the joint.
