3Racing 3RAC-NF40/GO Performance Gold 4mm Flanged Lock Nuts  [3RAC-NF40/GO]

Race-Focused 3Racing 3RAC-NF40/GO Flanged Lock Nuts

For racers and tuners, the 3Racing 3RAC-NF40/GO 4mm aluminum flanged lock nuts provide a lightweight, secure fastening option. The alloy construction minimises unsprung and rotating mass while the flange ensures a stable clamp on hubs and linkages during aggressive driving and setup changes.

Setup-Oriented Fastening

The flanged design increases contact area to reduce micro-movement under load, which helps preserve alignment and handling precision. Use these nuts when refining toe, camber, or wheel offset to maintain predictable results between runs.

Maintenance and Tuning Notes

These nuts are straightforward to service trackside with standard nut drivers and help speed routine adjustment cycles. Inspect mating threads and flange faces during setup to ensure reliable seating and repeatable torque values.
