Collection: ZPE Griptec

Griptec® by ZPE is a micro machining technology. This technology allows the maximum grip force to be applied to the pulley(s) and belt without adversely effecting your drive belt. Their Pulleys and Hubs are made from billet 7075 T6 Aluminum.
This grade of Aluminum is much stronger and harder than billet 6061-T6. This gives us a strength similar to steel but with the light weight performance of Aluminum, further we hard anodize our parts for additional protection.
This combination gives us the best that each material has to offer in strong light weight and tough component. Most photos are stock but you get the idea...
