What is the purpose of a piston pin lock?

A piston pin lock, also known as a wrist pin retainer, is used to keep the wrist pin securely in place within the piston. This prevents the wrist pin from moving or coming out during engine operation, which is critical for engine health.

How many pin locks are included in this set?

This set from Manley Performance includes eight .054-inch round wire lock clips. This is typically enough for four pistons, assuming each piston uses two locks.

Are these pin locks compatible with all engines?

These are .054-inch round wire locks, a common size for many Subaru and Saab engines. It's always best to confirm the specific wrist pin lock size required for your engine before purchasing.

About this part

Product Details

In this set, you get eight .054-inch round wire lock clips from Manley Performance. These are used to secure the wrist pin inside the piston, keeping it from walking out during engine operation. They are a crucial part of the piston assembly, especially when you're rebuilding or modifying an engine.

Manley is known for making well-built engine components, and these wire locks are no exception. They are made from strong round wire that holds its shape and provides a reliable grip on the wrist pin. The .054-inch size is a common specification for many performance and stock applications, ensuring a snug fit in the piston groove. Proper installation is key to their function; they need to be seated correctly in the piston groove to prevent them from coming loose.

This set is designed to fit a range of vehicles, including models like the Subaru Impreza, Forester, and Legacy. If you're working on one of these engines and need to replace your piston pin locks, this set from Manley is a solid option.
