5.0 out of 5 stars 1 Customer Reviews

Wrist pin locks, also known as retainers or clips, are small fasteners that secure the wrist pin in place within the piston, preventing the wrist pin from moving during engine operation, ensuring proper piston and connecting rod movement.

Diamond Pistons wrist pin retaining locks/clips are available for wrist pin sizes ranging from .490 in. to 2.000 in. The locks are offered in single Spirolox, double Spirolox, round wire locks, and Tru-arc locks. The round wire locks require chamfered wrist pins. Order the size needed for your installation.
