When you push a car hard over rough terrain, fasteners can be the weak link. The 3RACING 4mm serrated aluminium locknut set in blue helps keep key components fastened, reducing roadside repairs and improving session uptime. They are well suited to bashing and club racing alike.
The serrated design increases bite on mating parts to reduce the chance of nuts vibrating loose. Their low mass keeps the setup nimble, so you do not pay a handling penalty for improved retention.
Use these 4mm locknuts on wheel hubs, suspension linkages, steering assemblies and other threaded points where a secure fit is needed. The blue finish is both functional for quick ID and adds a clean look to a customised build.
