That motor's 7 years old.

We lose $$ on service!
EPA made me do it!
Parts at central warehouse, you'll get them next month.

REPLACEMENT PISTONS

MASTERTECH presents pistons for rebuilding your motor. These pistons are made by WISECO, a company started in 1941 by Clyde Wiseman, an old boat racer just like me who had a better idea. The company has expanded their line to include many applications including automotive and motorcycle, and is the piston of choice for use with today's fuels. All pistons come complete with rings, wristpins and retainers.
