Carrillo 827X063SWL Wire Lock Wrist Pin Clip 21mm

Wire locks hold the wrist pin in the piston, so the pin stays put during engine operation.

Key Features:

• Made from high-quality carbon spring steel or a chrome silicon based alloy
• Black oxide coated, oil dipped and sealed to resist corrosion
• Two locks are required per piston

A wrist pin is the link between the piston and connecting rod. It sees heavy loads in alternating directions, so a secure lock is an important part of a piston and rod assembly.
