Pro X High Compression Piston Kit
Ryan in PA
No instructions
This piston worked great but it comes with a copper/gold looking ring and a black ring and didnt say what ring goes where, the copper/gold closest to the top of the piston then black then the small one then the wrinkle oil ring then the other thin silver ring was so hard to figure out which on went where. Other than that, great product
