Replacement Piston kit designed by IMD Piston Co. and manufactured for IMD Piston Co. England

The pistons are within a 5 gramme range of the original piston.

The ring sets utilise the 3 piece oil control type offering excellent sealing to the cylinder wall.

All IMD pistons are made from the latest specification silicon aluminium alloy material.

This conforms to the required percentages of specialist metals, the most important of which is silicon. Silicon has been proved conclusively over a prolonged period, to give the best ring groove wear rates coupled with a low coefficient of low expansion rates. Strength has been achieved using a modern construction technique which has allowed the weight to be reduced in the piston. The weight of the piston is the most important factor in engine design, since the effect of reciprocating weight is transferred directly in terms bearing loads, engine balance and maximum permissible speed. The lighter the pistons are, then the lower are the loads on the crankshaft main bearings.

IMD have achieved piston weights comparable with the original parts, and will in the future improve upon this through innovative design.

This reduction of weight is now common place in automotive piston manufacturing worldwide, our pistons conform to this industry practice without any compromise, and are kept to the lowest level concomitant with adequate strength.
