3RACING 3RAC-NS40/PU Purple Serrated Locknut Set (8pcs) - Racing Grade  [3RAC-NS40/PU]

Performance Locking for Setup Stability

The 3RACING 3RAC-NS40/PU serrated locknut set provides reliable locking where consistent clamp is required in a race environment. The purple finish makes it easy to identify tuning parts in the pits while the serrated face helps preserve setup between runs.

Racing Advantages of Serrated Nuts

Serrations deliver repeatable resistance to rotation, allowing teams to trust suspension and wheel fastenings during heats. The reduced need for re-tensioning supports quicker turnaround between runs and more consistent lap times.

Applications in Tuning and Maintenance

These locknuts are well suited to wheel hubs, shock mounts and other critical fastenings used in competitive 1/10 class cars. They integrate with common hardware to provide a low-cost tuning upgrade for racers looking to stabilise their setups.

Installation and Pit Tips

For reliable service, start threads by hand and use the correct torque technique to avoid over-stressing screws. Keep spare locknuts on hand for quick replacement during practice and race day maintenance.
