Vertex pistons are manufactured using Low-Ex aluminium alloys with 12%, 18% or 21% silicon, produced via gravity casting or hydraulic forging. A heat treatment process refines the material structure, followed by CNC machining with diamond tools for specific surface finishes. Every Vertex piston undergoes rigorous quality control. Vertex pistons feature a Molybdenum Bisulphite black coating for break-in and friction reduction, and a Phosphate Coating for increased hardness, surface porosity, and Molybdenum Coating adhesion, doubling coating durability. This is a Grade B, 53.94mm single ring piston.

FULL DESCRIPTION
Vertex Grade B 53.94mm Single Ring Piston
The Vertex Grade B Single Ring Piston is engineered for high performance and durability, utilizing exotic Low-Expansion (Low-Ex) silicon-charged aluminium alloys. By incorporating 12%, 18%, or 21% silicon content depending on the specific application, these pistons offer superior structural integrity and thermal resistance.
Vertex employs advanced manufacturing processes, including gravity casting or hydraulic forging, followed by a precision-controlled heat treatment cycle. This ensures a refined material structure that meets the rigorous demands of competitive engine performance.
Key Features:
- Precision Machining: Produced using state-of-the-art CNC technology and diamond tooling for exact surface finishes.
- Advanced Coatings: Features a Molybdenum Bisulphite black coating to assist in the break-in process and reduce internal friction.
- Phosphate Coating: Includes an all-over phosphate treatment that increases surface hardness and provides light porosity for superior adhesion of the Molybdenum coating, significantly extending durability.
- Quality Assurance: Every piston undergoes a thorough manual and automatic quality control inspection to ensure peak performance standards.
- Specific Sizing: Grade B piston with a 53.94mm diameter designed for optimal cylinder clearance.
Whether you are performing a routine rebuild or a high-performance engine upgrade, this Vertex piston provides the reliability and technical advancement required for consistent power delivery.
