Namura Technologies Piston Circlip Retaining Ring

Namura Technologies piston circlips (also called wrist pin clips, piston pin retainers or snap rings) hold the wrist pin in place inside the piston bore. They keep the pin from shifting sideways and contacting the cylinder wall, which helps protect the piston, pin and cylinder during engine operation. They suit top-end rebuilds, piston replacements and general engine maintenance on powersports and motorcycle engines.

Key Features:

• Retains the piston wrist pin securely in the piston pin bore
• Helps prevent pin walk and the cylinder damage it can cause
• From Namura, a supplier of pistons, ring sets, cylinders and gasket kits for powersports engines
• Namura piston kits are supplied with a wrist pin, circlips and rings, so this part suits Namura-based rebuilds
• A low-cost part to replace during a top-end rebuild

Fit new circlips every time you rebuild a top end. Make sure each one is fully seated in its groove before you install the piston. Select the correct child item for your engine's wrist pin and piston.
