What is the purpose of a wrist pin retainer?

A wrist pin retainer, also known as a snap ring or lock, keeps the wrist pin securely seated within the piston. This prevents the wrist pin from moving out of place, which is essential for the proper functioning of the piston and connecting rod assembly.

What does '.073 ROUND' refer to?

This specification refers to the dimensions of the wire used to make the retainer. '.073' indicates the diameter of the wire in inches, and 'ROUND' specifies its cross-sectional shape. This size is important for ensuring a proper fit within the groove machined into the piston.

Are these retainers suitable for all engine builds?

These are part of Manley's Sport Compact series, indicating they are intended for performance applications. While they are well-built, it's always best to confirm that this specific size and type of retainer is recommended for your particular engine build and piston design.
