We choose our piston rings for durability and quality of materials.

We opt to sell the more expensive sets of cast iron rings as opposed to the cheaper black oxide ductile cast iron rings that are on standard replacement pistons.  These are definitely an upgrade!

We cannot cover lean seizures, debris damage or other installation errors.  If you are unhappy with the fit and finish of the product we will gladly accept return of the of it if it is in “LIKE NEW” condition.
