Common questions
What does .010" oversize mean for these rings?
These rings are manufactured for cylinders that have been bored .010 inches larger than the stock diameter. They are essential for achieving a correct seal in an oversized bore.
Will these rings fit a stock 1340cc Shovel engine?
No, these rings are specifically for 1340cc Shovel engines with .010" oversized cylinders. Stock bore engines require standard-sized piston rings.
Do I need special tools for installation?
Piston ring installation typically requires a piston ring compressor tool to properly seat the piston into the cylinder without damaging the rings. Always consult your service manual.
