Secure the front train from your machine with theSpecial Rocket Nut Original Builder Birelart (Original Birelart Genuine Parts). This specific nut is the official spare part to ensure the locker lock and maintenance of front hubs or front rims (depending on your configuration) on the threaded axis of your rockets.
Machined according to an ultra-strict specification by the Italian plant, this nut differs from standard models of trade by its specific screw and flange or its integrated mechanical braking system adapted to the extreme constraints of competition karting. Subjected to constant vibrations, to violent load transfers during braking and high-speed curve, it ensures that no mechanical game is created on the front axle, thus preserving the surgical accuracy of the train of your train.
