Race-Grade Serrated Locknuts for Tuning

The 3Racing 3RAC-NS40/RE Red Serrated Aluminum Locknuts provide a straightforward retention upgrade for racing setups. The serrated face increases friction against mating surfaces to reduce loosening under high-frequency vibration, while the light aluminium construction minimises added mass on critical assemblies.

Setup and Tuning Benefits

These nuts are useful when refining suspension and steering geometry: they help maintain clamp force between set-up runs and reduce the need for frequent re-torquing. The anodised red finish aids quick visual checks for missing or loose hardware during pit stops.

How do serrated locknuts affect corner-to-corner consistency?

By reducing fastener back-off, serrated locknuts help preserve initial setup geometry, which supports repeatable handling across multiple runs.

Are they compatible with standard race hardware?

They are designed for M4 threads and pair well with common steel or titanium studs used in competition; verify thread matching before swapping.

When should I prefer serrated nuts over nylon locks?

Serrated metal locknuts are preferred where repeated assembly, heat exposure, or high vibration make nylon inserts less reliable; they offer durable mechanical grip without soft insert wear.
