These high strength jam nuts are designed to lock rod ends, Heim joints, and steering linkages securely in place, preventing loosening caused by vibration and repeated suspension movement.

Manufactured from high carbon steel and finished with a corrosion resistant zinc coating, these jam nuts are built for durability in high stress off-road, automotive, and industrial applications. Their low profile, six-sided design allows for easy wrench access while maintaining a compact footprint which is ideal for tight suspension and steering setups.

Sold individually, these jam nuts are available in both Right-Hand (RH) and Left-Hand (LH) thread options to properly match your rod ends.

Off-road, performance, and race applications

Jam nuts play a critical role in suspension reliability by locking rod ends in position and preventing unwanted rotation under load. Using matching thread direction (LH or RH) ensures proper adjustment and secure clamping force, especially in high vibration environments like off-road and racing applications.

High carbon steel construction provides increased strength over mild steel, while zinc plating helps protect against corrosion from moisture, mud, and trail debris.
