Fitment, Shipping & Product Support
The Axiom Heavy Duty Heim Joint (SKU JMXR10T-F1) is a high-strength spherical rod end for UTV suspension and steering linkage applications requiring a 5/8" shank diameter, 5/8" bore, and right-hand thread. Center ball crafted from 52100 bearing steel, heat-treated and hard-chromed for long service life. Chromoly steel body with Kevlar-lined internals absorbs impact and vibration while keeping steering response tight. 3-piece rod end construction for high strength. Corrosion-resistant finish. Heim joints allow precise multi-axis articulation at suspension and steering pivot points — worn or damaged joints introduce play that causes steering wander, vibration, and accelerated wear on surrounding components. Fits Axiom Supply systems and many other aftermarket tie rod and radius rod setups — not compatible with OEM tie rods. This is a wear item; inspect and replace as needed. Sold individually — order the quantity required for your application.

Critical Compatibility
| Configuration | Notes |
|---|---|
| OEM tie rods | Not compatible — this joint is for aftermarket tie rod and radius rod systems only |
| Left-hand thread applications | Not interchangeable with this right-hand part — installing the wrong direction will not allow correct adjustment and can back out under load |
| Missing or improperly torqued right-hand jam nut | The joint will back out under vibration and load — never operate without one properly installed |
| Mismatched shank/bore dimensions | Will not fit correctly and can cause joint failure under load — verify exact dimensions before ordering |
Common Questions
Will this work on my factory tie rod?
No. This joint is built for aftermarket tie rod and radius rod systems, not OEM factory hardware.
Does this come with a jam nut?
No. A right-hand thread jam nut is required and must be purchased separately.
What's the difference between this and the zinc-plated version?
This is the standard-finish version. If you want the zinc-plated finish at the same 5/8" x 5/8" RH dimensions, order JMXR10T-F1-XXVEZ.
What if I need the left-hand version instead?
Order JMXL10T-F1, the same 5/8" x 5/8" configuration in left-hand thread.
The Obsidian Take
The JMXR10T-F1 is for the UTV builder or repairer needing a genuine heavy-duty replacement heim joint at the 5/8" x 5/8" size — 52100 hard-chromed ball, chromoly body, Kevlar-lined internals, 3-piece construction.
This is a wear item by the manufacturer's own description — inspect it regularly and replace at the first sign of play. Confirm thread direction (right-hand) and both dimensions before ordering.
Non-Returnable Notice: Installed steering and suspension components are non-returnable. Confirm thread direction and dimensions match your application before ordering.
