The kit includes the barrel, piston, pin, clips and the piston rings, gaskets and head studs.
The kit is made in Taiwan by a well known piston manufacturer whose products end up in many different branded boxes.
The top ring is a standard keystone type, which is much more robust than the dykes type that is found on some other kits. The overall quality is excellent. Set it up right and you will get good power and great reliability.
I can also supply gaskets, piston kits in oversizes and piston ring sets.
