RaceLox Performance hubs are made by SMT Machining to be as light as possible but still maintain the strength SMT is renowned for. We took 9 ounces off per hub side for an average weight savings of 18 ounces per wheel. They are still just as strong as our standard hubs and actually incorporate a locking system for the hub bolts to keep them locked in no matter the stress you put them through. SMT hubs also incorporate stainless steel pins to prevent the rotation of the hubs on the wheel blank even before they are bolted together. If you are looking for unique wheel options that increase performance and look incredible while doing it, the RaceLox hub from SMT Machining is exactly what you are looking for.
