WOD Chromoly Rod End - 1-1/4"-12 Shank, 1" Bore
XMR16
The WOD 1-1/4"-12 Chromoly Rod End is built for extreme-duty suspension, chassis, and linkage applications where maximum joint strength and durability are required. Its massive 1-1/4"-12 shank and full 1" bore make it an ideal choice for four-link suspensions, ladder bars, competition buggies, rock bouncers, and heavy custom builds using 1" 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 provides smooth articulation with minimal maintenance. With a 76,200 lb radial static load rating, it is engineered for high vehicle weights, large tires, aggressive suspension geometry, and repeated shock loads in demanding off-road, racing, performance, and industrial 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
When should I use a 1-1/4"-12 rod end?
A 1-1/4"-12 rod end is intended for heavy vehicles, large tires, high horsepower, long suspension links, and competition applications that generate severe impact and shock loads. It provides substantially greater shank strength and load capacity than smaller rod ends.
Why use a full 1" bore?
A full 1" bore allows the joint to be mounted with 1" hardware without reducing the bolt size through stepped spacers. This configuration is commonly used where the brackets, bolts, and surrounding structure are designed around maximum connection strength.
What is the benefit of a chromoly rod end?
Heat-treated chromoly steel provides increased tensile strength and fatigue resistance compared with many standard mild-steel rod ends. This makes it better suited for suspension and linkage systems exposed to repeated impacts, vibration, and high loads.
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 76,200 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 suspension 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.
When should misalignment spacers be used?
Misalignment spacers are used when additional angular travel, a narrower installed width, or a different mounting configuration is required. Spacer dimensions must match the 1" rod end bore, mounting hardware, and bracket spacing.
How do I prevent rod end binding?
Mock up the complete suspension or linkage and cycle it through its full range of compression, droop, steering movement, and articulation. The ball must retain adequate angular movement without the rod end body or shank contacting the mounting brackets.
