Female Chromoly Rod End – Hard Chrome – Heavy-Duty Heim Joint
Upgrade your linkage system with our heavy-duty female rod ends manufactured to strict X-Series specifications. These heim joints are constructed from heat-treated 4130 Chromoly steel and finished with a hard chrome plating, offering superior structural strength and corrosion resistance compared to standard mild steel or economy joints.
The ball is precision-ground 52100 bearing steel seated in a self-lubricating Nylon/PTFE race. This maintenance-free design isolates vibration and creates a tighter tolerance than metal-on-metal alternatives, making it the ideal choice for critical motorcycle and powersports applications.
Common Applications:
- Custom Linkages: Use the 5/16-24 female end to cap off threaded rod for custom gear shift linkages or lightweight control arms. (Note: 5/16-24 is the standard thread pitch for most Harley-Davidson shift linkages).
- Brake Stays & Torque Arms: The 3/8-24 female end is widely used for anchoring brake calipers to the frame or swingarm, where high tensile strength is required to prevent failure under braking load.
- Precision Adjustment: Perfect for systems requiring fine-tuning, such as clutch rods, throttle linkages, and master cylinder pushrods.
