FK Replacement Heavy Duty Heim Joint for UTV by Kryptonite delivers unmatched strength, precision, and reliability for your off-road suspension system. Engineered for superior performance, these rod ends are designed to fit Kryptonite and many other leading brand UTV tie rod and radius rod systems. Whether you’re upgrading or replacing worn components, these FK JMX and JMXL Series rod ends ensure optimal steering control and long-lasting durability, even under the most demanding trail conditions.
Each rod end is built from aircraft-grade 4130 chromoly steel for maximum strength and impact resistance. The Kevlar-reinforced Teflon liner provides smooth motion and reduces friction, while the zinc plating protects against corrosion and rust. The center ball, made from precision-ground and heat-treated 52100 bearing steel, is hard chrome plated to deliver exceptional wear resistance and consistent performance over time.

These FK rod ends are part of the industry-leading JMX/JMXL Series, trusted by off-road enthusiasts and professional racers alike. Each joint features a three-piece precision design that maintains tight tolerances for smooth articulation and responsive handling. The result is a rod end that performs reliably in extreme conditions, giving your UTV the stability and control it needs to conquer any terrain.
Because all rod ends are wearable components, periodic replacement is recommended to maintain optimal performance. Sold individually, these parts allow you to choose the correct thread direction—right-hand (JMX) or left-hand (JMXL)—to match your existing tie rod or radius rod configuration. Please note that these rod ends are designed for aftermarket systems and will not fit OEM tie rods.
