Rock Jock CE-9110C 2.5 in. Weld-On Chromoly Johnny Joint Rod End Internally Greased

The Rock Jock CE-9110C is a 2.5 in. weld-on chromoly Johnny Joint rod end designed for off-road suspension fabricators and custom control arm builders. Unlike a standard heim joint that tops out at 22 degrees of articulation, this Johnny Joint delivers 30 degrees of unrestricted multi-directional movement, making it the preferred choice for high-articulation suspension builds.

This joint uses an internally greased design with a cross-drilled pivot ball and is serviced via the included Grade 8 greaseable bolt — eliminating the need for an external zerk fitting on the body. Grease is delivered directly through the thru-bolt to lubricate the joint from the inside out for thorough, reliable maintenance.

Key Features:

• 30° of articulation in any direction — significantly more than a standard heim joint
• Chromoly outer barrel — weldable .180 in. wall machined 4130 chromoly tubing for maximum strength and weldability
• Cross-drilled, heat-treated center ball — drilled at 0.562 in. for thru-bolt lubrication
• High-density urethane bushings — encapsulate the inner ball to provide cushioning, noise isolation, and impact absorption that heim joints cannot offer
• 2.625 in. overall width (OAW) — standard mounting width for common control arm applications
• Internally greased — lubrication delivered via the included greaseable bolt rather than an external fitting
• 2 heavy-duty, heat-treated side washers and a snap ring retain the joint internals securely
• Rebuildable design — rebuild kits available to extend service life
• Includes: Grade 8 greaseable bolt with nut and washers
• Sold individually (each)

Rock Jock Johnny Joints have been a staple of serious off-road suspension builds since 1996, trusted by fabricators building everything from trail rigs to race-ready suspension systems.
