Vertex pistons are manufactured using Low-Ex aluminium alloys, silicon charged to 12%, 18% or 21% depending on the application. They are made using either gravity cast or hydraulic forging processes, with material structure refined through a high-tech heat treatment in an automatic HT implant with solubilization by quench in hot water. Machining is completed using the latest CNC machines and software with diamond tools to achieve specific surface finishes for the final application. Every Vertex piston undergoes rigorous manual and automatic quality control. Vertex pistons are coated with a special Molybdenum Bisulphite black coating for break-in and to reduce friction. A new, all over, Phosphate Coating has been introduced which offers increased hardness and surface porosity for superior adhesion and durability of the Molybdenum Coating. This piston is 53.96mm.

FULL DESCRIPTION
Vertex High-Performance Racing Piston - 53.96mm Grade D
Engineered for precision and reliability, the Vertex racing piston is designed to meet the rigorous demands of high-performance engines. Manufactured using advanced metallurgical processes and cutting-edge machining techniques, this piston offers superior durability and performance consistency under intense racing conditions.
Advanced Material Composition
Each piston is crafted from specialized Low-Ex (low expansion) silicon-charged aluminium alloys, with silicon content tailored specifically to the application requirements (12%, 18%, or 21%). This alloy selection ensures optimal thermal stability and structural integrity during high-revving operation.
Key Features
- Precision Manufacturing: Produced using either gravity casting or hydraulic forging, followed by a sophisticated heat treatment process in an automatic HT implant for refined material structure.
- CNC Machined: Utilizes the latest CNC technology and diamond-tipped tooling to achieve exacting tolerances and specific surface finishes required for professional racing engines.
