FORGED PISTONS

These pistons are manufactured exclusively for us by both Omega. They are designed for competition and therefore are much stronger but are equally good for road use. They are a direct replacement for the originals and require no special liners, head gaskets, etc. To keep the compression ratio as high as possible they are machined in height to the upper-most limit and this means, if the engine block has been skimmed at any time, the piston top may have to be machined to suit. This is standard practice with all good engine builders and therefore should not pose any problem. These pistons come in sets of six, including gudgeon pins, circlips and rings.

Please note: The sizes quoted are finished bore sizes and all tolerances have been allowed for on the piston. We have used metric sizes in order to take advantage of the latest piston ring technology. Replacement rings available, please state diameter and width when ordering.
