Description
Overview:
These Connecting Rod Big End Shells U/S .020'' (pairs) are genuine Villiers bearings for the Mk 40 industrial engine. Supplied as a matched pair, they sit in the big end of the connecting rod to provide a controlled, low-friction running surface on the crankpin.

Manufactured from high-quality bearing materials with precise geometry, they help reduce wear, prevent knock, and keep the engine running smoothly.
