WISECO CW21 Round Wire Wrist Pin Locks for 21 mm Pins, Pair

Secure piston wrist pins with WISECO CW21 Round Wire Wrist Pin Locks, designed for applications using 21 mm wrist pins. This pair of wire-style pin locks provides a dependable retention solution for performance engine builds, rebuilds, and replacement applications where proper wrist pin security is essential.
The locks are manufactured from durable steel with a 0.049-inch wire thickness for reliable installation and service performance. Their round wire design fits the intended wrist pin groove and helps prevent lateral wrist pin movement during engine operation. Use the WISECO part number CW21 to confirm compatibility with your piston and connecting rod assembly before installation.
These wrist pin locks are supplied as a pair, making them convenient for servicing one piston assembly or replacing both retainers during an engine rebuild. Proper installation is important: verify the locks are fully seated in their grooves and inspect the piston, wrist pin, and retaining grooves for damage or excessive wear. Follow the piston manufacturer's installation instructions for the best results.
