Piston Pin Lock Rings, Round Wire, 0.905 in. Pin, Pair

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.
