Piston Kits

Vertex

Vertex Piston Kits Vertex pistons have an outstanding reputation for quality and performance. Each gravtiy cast piston is created with only premium aluminium alloys utilizing an 12-21% silicon content. The silicon content in Vertex pistons is crucial to the quality of the piston - it’s critical in decreasing thermal expansion which, when an engine reaches normal operating temperatures, can change the geometry of the piston. Controlling this expansion means Vertex pistons can be run at tighter tolerances for more power, less noise and a longer lifespan of the piston. When it comes to power and perforance, Vertex pistons are hard to beat. Forged to the highest quality 2618 aluminium alloy. To aid in the break-in process, and reduce wear, Vertex pistons utilizes a unique Molybdenum Disulphide (MOS2) coating on the piston skirt.
