Vertex pistons are manufactured using Low-Ex aluminium alloys with 12%, 18% or 21% silicon content depending on the application. They are produced using gravity casting or hydraulic forging, followed by heat treatment in an automatic implant with solubilization by quench in hot water. Machining is done with the latest CNC machines and diamond tools to achieve specific surface finishes. Each piston undergoes rigorous manual and automatic quality control. Vertex pistons feature a special black Molybdenum Bisulphite coating for break-in and friction reduction. A new, all over Phosphate Coating, developed following Formula One engine advancements, offers increased hardness, light surface porosity, and superior adhesion qualities of the Molybdenum Coating, doubling its durability. This is a single ring replica piston with a 53.95mm bore.

FULL DESCRIPTION

High Performance Vertex Replica Piston

Restore your engine performance with this premium Vertex replica piston. Engineered for durability and precision, this 53.95mm single ring piston is designed to meet the rigorous demands of high-performance engines, ensuring reliable operation and optimal power delivery.

Advanced Manufacturing and Material Quality

Vertex pistons are manufactured using specialized Low-Ex aluminium alloys charged with high levels of silicon to provide low thermal expansion and superior strength. Each piston undergoes a sophisticated hydraulic forging or gravity casting process, followed by an advanced heat treatment in an automated implant to refine the material structure. This ensures a component that is both lightweight and exceptionally durable under extreme engine conditions.

Precision Engineering and Friction Reduction

Precision is guaranteed through the use of state-of-the-art CNC machining and diamond tooling, allowing for specific surface finishes tailored to your engine requirements. To further enhance performance, this piston features a dual-layer coating system:

  • Molybdenum Bisulphite Coating: A specialized black coating applied to aid the break-in process and significantly reduce internal cylinder friction.
  • Phosphate Coating: Drawing on Formula One technology, this all-over coating increases surface hardness and provides superior porosity for the Molybdenum layer to adhere to, effectively doubling the durability of the piston coating.

Quality Assurance

Every Vertex piston is subject to stringent manual and automatic quality control inspections before leaving the factory. By choosing Vertex, you are installing a component engineered for high-level performance and long-lasting consistency.
