Description
Jam nuts are critical for maintaining rod end integrity under load and vibration—they lock your primary fastener in place and prevent catastrophic loosening during high-stress racing or performance driving. This FK Steel Jam Nut is engineered to pair seamlessly with 1/2-20 rod ends, delivering reliable fastening without adding unnecessary weight or complexity to your suspension geometry.
Whether you’re tuning a competition car or upgrading a street-performance build, this zinc-oxide coated steel jam nut ensures your rod end assembly stays tight through lateral g-forces, bump steer adjustments, and repeated thermal cycling.
