Piston cups seal on their outer lip and are held in place by a follower plate. To maximize product availability, our piston cups do not come with a pre-cut bolt hole. Our machining department can quickly cut the appropriate hole size for an application. See piston cups literature for more information.
We also stock Edbro and Renn piston cups in unique sizes. Contact us for more details.
