Vertex pistons are manufactured using Low-Ex aluminium alloys with 12%, 18%, or 21% silicon depending on the application. They are made using gravity casting or hydraulic forging, followed by a heat treatment process in an automatic HT implant with solubilization by quench in hot water. Machining is completed using CNC machines and diamond tools to achieve specific surface finishes. 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 friction reduction, and a newer Phosphate Coating for increased hardness, light surface porosity, and enhanced durability. This replica piston has a 66.34mm bore and twin rings.

FULL DESCRIPTION
Vertex 66.34mm Twin Ring Replica Piston
The Vertex Grade A 66.34mm Twin Ring Replica Piston is engineered for high performance and reliability. Manufactured using advanced low expansion silicon-charged aluminium alloys, these pistons are built to withstand the rigours of demanding engine environments while maintaining structural integrity.
Advanced Manufacturing and Quality Control
Vertex utilises state-of-the-art gravity casting and hydraulic forging processes, refined through precise heat treatment cycles in automated HT implants. Each piston is machined on high-end CNC equipment with diamond tooling to ensure exact surface finishes tailored to specific engine requirements. Every unit undergoes rigorous manual and automatic quality control inspections to meet professional-grade standards.
Superior Coating Technology
This piston features a dual-layer coating system designed to optimise performance and longevity:
- Molybdenum Bisulphite Coating: A specialized black finish that assists in the break-in process and reduces friction during cylinder operation.
- Phosphate Coating: Inspired by Formula One engine technology, this all-over coating increases surface hardness and provides light surface porosity. This enhances the adhesion of the Molybdenum coating, effectively doubling its durability.
Key Features
- High-quality twin ring design for optimal compression sealing.
- Precision engineered 66.34mm diameter.
- Constructed from high-tech, low-expansion aluminium alloy.
- Advanced friction-reducing coatings for extended engine life.
- Developed for consistent performance under thermal stress.
