WOD Chromoly Rod End - 7/8"-14 Shank, 7/8" Bore
XMR14
The WOD 7/8"-14 Chromoly Rod End is built for suspension, chassis, and linkage applications that require a heavy-duty joint with a full 7/8" bore. Its 7/8"-14 shank and matching 7/8" bore make it an excellent choice for four-link suspensions, ladder bars, custom chassis systems, and high-load fabrication projects using 7/8" mounting hardware.
Manufactured from heat-treated chromoly steel with a hardened 52100 bearing steel ball and a self-lubricating Nylon/PTFE race, this rod end delivers smooth articulation with minimal maintenance. With a 45,051 lb radial static load rating, it provides dependable strength for demanding off-road, racing, performance, and industrial linkage applications.
Note: Verify thread direction, mounting width, bolt size, and required articulation before ordering. Jam nuts, misalignment spacers, mounting hardware, and threaded bungs are sold separately unless otherwise noted.

FAQ
Why use a 7/8"-14 rod end with a full 7/8" bore?
This configuration combines a heavy-duty 7/8"-14 shank with mounting hardware of the same diameter. It is a strong option for suspension and linkage systems where builders do not want to reduce the bolt size with stepped misalignment spacers.
How does this compare with a 7/8"-14 rod end with a 3/4" bore?
The full 7/8" bore accepts larger mounting hardware, while the 3/4" bore version is designed around more common 3/4" bolts. The correct choice depends on bracket design, hardware size, packaging, and the strength requirements of the complete suspension connection.
Why is the radial static load rating lower than some smaller-bore versions?
A larger bore removes more material from the ball and joint assembly. Although the full 7/8" bore allows the use of larger mounting hardware, rod end capacity is affected by the complete geometry of the body, ball, race, and bore—not shank size alone.
What is the benefit of a chromoly rod end?
Heat-treated chromoly steel provides increased strength and fatigue resistance compared with many standard mild-steel rod ends. This makes it better suited for suspension, chassis, and linkage applications exposed to repeated impacts and vibration.
What does the Nylon/PTFE race do?
The Nylon/PTFE race creates a low-friction surface between the ball and rod end body. It supports smooth articulation while helping reduce wear, noise, contamination, and routine maintenance.
Does this rod end require greasing?
No routine greasing is required. The race is self-lubricating and self-sealing, although regular inspection for wear, looseness, contamination, corrosion, or physical damage is still recommended.
What does the 45,051 lb radial static load rating mean?
Radial static load measures force applied perpendicular to the rod end bore during a controlled static test. It does not account for repeated impacts, fatigue, side loading, bending, loose hardware, or improper suspension geometry.
Can the radial static load rating be used as the suspension's working load?
No. The complete connection is limited by its weakest component, including the rod end, mounting bolt, spacers, brackets, threaded bung, welds, suspension link, and chassis structure. Proper engineering and an appropriate safety factor are required.
How much thread engagement should be maintained?
The rod end should retain substantial thread engagement inside the threaded bung or link at its final adjustment position. Avoid operating the joint near the end of the threads, where the shank is more vulnerable to bending and thread damage.
How do I prevent rod end binding?
Mock up the complete suspension or linkage and cycle it through its full operating range. The ball must retain adequate angular movement without the rod end body or shank contacting the mounting brackets.
