RockJock CE-9110P-28 Johnny Joint 2.5in Weld-On Rod End 2.625x.640 Ball

Vehicle Fitment

• Universal - Designed for fabricators, suspension builders, and custom off-road suspension applications
• Commonly used in RockJock suspension systems across Jeep Wrangler (YJ, TJ, LJ, JK, JL), Jeep Gladiator (JT), Jeep Cherokee (XJ), and other solid-axle off-road platforms

Fitment Notes

• Weld-on installation - must be welded to fabricated or existing control arm, trac bar, or link tube; no bolt-in version of this joint
• No bolt included - thru-bolt (.640 in. bore) must be sourced separately to match application
• Same 2.625 in. mounting width as the standard CE-9110P but with a larger .640 in. bore - choose when a 5/8 in. class thru-bolt is required instead of the standard 9/16 in.
• Do NOT over-grease - use a hand pump grease gun only; pneumatic or electric grease guns can damage the joint
• Compatible with RockJock rebuild kit CE-9110RK for long-term serviceability

Features

• Up to 30 degrees of unrestricted articulation in any direction - exceeds the 22-degree limit of a standard heim joint
• High-density "Tough 88" urethane bushings absorb shock and dampen vibration for quiet, smooth on-road use
• Heat-treated center ball cross-drilled for thru-bolt lubrication and extended service life
• Weld-on .180-inch wall machined DOM steel outer shell for maximum fabrication strength and flexibility
• External zerk fitting allows grease access without disassembly or joint removal
• Fully rebuildable - replacement urethane bushings and hardware available via CE-9110RK
• Two heavy-duty heat-treated side washers and a snap ring retain joint internals under extreme loads
• Backed by RockJock's Limited Lifetime Warranty

Product Description

The RockJock CE-9110P-28 is a 2 1/2-inch weld-on Johnny Joint rod end with a 2.625 in. x .640 in. ball - sharing the same 2.625 in. mounting width as the standard CE-9110P base variant, but opening up to a larger .640 in. thru-bolt bore for applications that require a 5/8-inch class bolt instead of the more common 9/16-inch. Like all Johnny Joints, it provides up to 30 degrees of unrestricted articulation through a high-density urethane bushing design, delivering far more range of motion than a standard heim joint while simultaneously cushioning road vibration and trail impacts for quiet, smooth on-road driving behavior.

The weld-on .180-inch wall machined DOM steel outer shell integrates into fabricated control arms, trac bars, and link tubes across a wide range of off-road platforms. The heat-treated center ball is cross-drilled for thru-bolt lubrication, and the external zerk fitting makes routine greasing quick and straightforward without removing the joint. No thru-bolt is included - source separately to match the .640 in. bore and application length. The joint is fully rebuildable using the CE-9110RK rebuild kit, and RockJock backs it with a Limited Lifetime Warranty.
