Race-Grade Serrated Locknuts for Secure Wheel Clamping

The 3Racing 3RAC-NS40/GO 4mm serrated aluminium locknuts provide consistent clamping for competitive setups. Engineered to seat firmly against common wheel faces, the serrated flange resists back-off under high vibration and repeated impacts typical of race conditions.

Functional Advantages for Tuners

Serrated geometry increases friction at the contact face, reducing the need for heavy thread locking while preserving adjustability for fine tuning. Aluminium construction lowers unsprung and rotating mass for improved transient response without sacrificing clamp strength.

Practical Fitment and Service Tips

These locknuts suit standard 1/10 scale hubs and are simple to service trackside. Inspect serrations for debris after runs and replace if serration edges or threads show damage to maintain reliable performance.

Improved retention keeps wheel alignment and balance stable between runs, which helps predictable handling and consistent lap times.
Check for abrasion on serrations and clean thread faces regularly; replace any nut with visible wear to avoid variable clamp force.
Aluminium offers an excellent strength to weight ratio for racing; when used with serrations it offers dependable retention while keeping rotating mass low.
