Precision Retention with 3RACING 3RAC-NS40/BU

For competitive setups where component security matters, the 3RACING 4mm serrated aluminium locknuts provide consistent clamping at multiple attachment points. These nuts help maintain alignment and reduce time spent re-tightening during test sessions.

Serration and Weight Considerations for Tuners

The serrated seating increases friction against mating surfaces to resist vibrational loosening without adding significant mass. Their aluminium construction supports low unsprung weight strategies while securing wheels, linkages and shock fittings.

Application Notes for Performance Builds

Use these 4mm locknuts on load-bearing threads across on-road and off-road cars. They are suitable where frequent setup changes occur and where reliable, repeatable retention is required during aggressive running.

What maintenance checks should I perform?

Inspect locknut seating and mating surfaces for wear each service interval. Replace any nut that shows rounded serrations or damage to ensure continued retention.

How do these affect repeated setup adjustments?

They offer reliable reassembly without time-consuming re-torquing in most cases, but monitor torque after multiple fit cycles as serration wear can reduce bite over long-term use.

Are these recommended for endurance events?

For endurance racing, combine the serrated locknut with periodic checks and optional removable thread compound to ensure long-term security under continuous vibration.
