Vertex Top End Piston Kit provide everything you need for your top-end rebuild, eliminating the hassle of sourcing components separately.

Kits are available for both 2-stroke and 4-stroke applications. 2-stroke applications include a wrist pin bearing. 4-stroke applications include a Hot Cams cam chain.

Vertex pistons – To handle internal pressure, Vertex’s pistons are forged from the highest quality 2618 aluminum alloy for superior strength and durability. Vertex uses unique piston profiles and compression ratios, offered in A, B, C and D sizes. To maximize power and performance while reducing blow-by and oil consumption.

Vertex gasket kits – The gasket kit contains all the necessary gaskets to rebuild your top end. Kit includes head, base and exhaust gaskets, as well as O-rings, that are necessary when removing the cylinder and head during routine maintenance.
