CCI Cylinder Stay | Harley-Davidson®

The new standard for Harley engine assembly.

When installing the second cylinder, the first cylinder can lift away from the crankcase as you rotate the engine. It's a common frustration that builders have worked around for years.

CCI Cylinder Stays solve it.

Designed to thread onto the cylinder studs, Cylinder Stays securely hold the installed cylinder against the crankcase while you rotate the engine and install the second cylinder. The result is a smoother assembly process, greater confidence, and one less thing to worry about during your build.

Whether you're rebuilding an engine in your home garage or assembling motors professionally, Cylinder Stays quickly become one of those tools you won't want to build without.
