JE Pistons chrome silicon wire lock, .669 inch diameter with .050 inch thickness, is a wrist pin retainer sold individually. Wire locks tend to spread side loads over more of the piston pin boss and are considered a stronger pin retention method compared with simple spiro locks. Variants such as hook wire locks include an integrated hook to prevent rotation; tru‑arc styles offer easier installation and reusability for lower horsepower applications.
