Piston and connecting rod

DESCRIPTION

The pistons are made of a high strength aluminum alloy with an anodized top ring groove and crown.

Piston skirts are coated with a solid lubricant (Molykote) to reduce friction and provide scuff resistance.

The connecting rods are made of ductile iron.

A pressed fit piston pin is used to attach the piston and connecting rod.
