These Mahle lock rings are designed for floating-pin pistons. Engines produced with press-fit pins can be converted to the "floating" type if the piston has provisions for a lock ring retainer. Many power-forged and hypereutectic pistons are designed to accommodate either style of pin. Pick up these Mahle lock rings for reliability in your rotating assembly.
