We are proud to feature AV&V valve-train products. For an excellent essay on their product, visit the AV&V Technical Information page.

We use our own line of valve seats. Our seats are cast from the same material used in Natural Gas engines, so you know they are built to withstand heat and offer quick dissipation.

Other vendors include S&S Cycle, Jims Machining, Eastern Motorcycle Parts, Rowe USA, and Zipper's Performance.
