How many pistons does this set of 8 retainers cover?

This set includes 8 round wire lock retainers. Since each piston uses two retainers (one on each side of the wrist pin), this set is sufficient for four pistons. This is typically enough for a 4-cylinder engine or half of a V6 or V8 engine.

What is the purpose of a wrist pin lock?

Wrist pin locks, also known as piston pin retainers, are crucial for keeping the wrist pin securely in place within the piston. They prevent the wrist pin from walking out, which could cause severe engine damage.

Are these locks suitable for high-performance engines?

Manley is a well-known brand in the performance engine parts industry. These retainers are made from strong wire and are designed for a secure fit, making them a popular choice for both stock replacement and performance engine builds.

Product Details

If you're rebuilding an engine and need to secure the wrist pins in your pistons, these Manley .061 round wire locks are a solid option. They're designed to fit snugly into the grooves on your piston and wrist pin, keeping them properly aligned and preventing any unwanted movement. This set includes eight retainers, which is enough for four pistons, making it suitable for most V6 and V8 applications.

Manley is known for making well-built engine components, and these retainers are no exception. They're made from strong, round wire that holds its shape and resists deformation, ensuring a secure fit. The .061 inch diameter is a common size for many performance and stock replacement pistons, offering a good balance of strength and ease of installation. When installing, make sure the wire lock is fully seated in its groove on both the piston and the wrist pin for optimal security.
