Big End Bearings

 

 

All our big ends use aerospace quality silver plated bearing cages supported between two hardened thrust washers.

Crank pins are of a two piece construction, enabling different materials to be used for the bearing race and the crankpin. 

These Bearing are direct replacements for the originals.
