Wiseco Piston Lock Rings

4.67 out of 5 stars 15 Customer Reviews

These Wiseco piston lock rings are designed for floating-pin pistons. Engines produced with press-fit pins can be converted to the "floating" type, providing that the piston has provisions for a lock ring retainer. Floating pins are preferred by most serious engine builders.
