Vertex Piston kits are comprised of a piston, ring, gudgeon pin & circlips.
Vertex pistons are manufactured using exotic aluminium alloys called Low-Ex (low expansion) Silicon & are manufactured using either a gravity cast or hydraulic forging process to make the blank parts and then the material structure is refined using a hi-tech Heat Treatment completed in an automatic HT implant with solubilisation by quenching in hot water. The machining process is completed using the latest CNC machines and software as well as the use of diamond tools. Produced to exacting OEM specifications they are in most cases the only choice from new build, through to service parts replacement.
