Vertex pistons are manufactured using Low-Ex aluminium alloys, silicon charged at 12%, 18%, or 21% depending on application. Pistons are made using gravity cast or hydraulic forging, with material structure refined by heat treatment. Machining is completed using CNC machines and diamond tools, achieving specific surface finishes. Every Vertex piston undergoes rigorous manual and automatic quality control. Pistons are coated with a special Molybdenum Bisulphite black coating for break-in and friction reduction. Vertex also offers a new Phosphate Coating for increased hardness, surface porosity, and superior adhesion and durability. Piston size is 54.21mm.

FULL DESCRIPTION
Vertex High-Performance Piston - 54.21mm Grade C
Engineered for precision and reliability, this Vertex piston is designed to restore power and performance to your engine. Manufactured using advanced metallurgical techniques, this piston offers the perfect balance of durability and lightweight performance, ensuring consistent output under demanding conditions.
Advanced Manufacturing Technology
Vertex utilizes proprietary Low-Expansion (Low-Ex) silicon-charged aluminium alloys to ensure structural integrity and thermal stability. Each piston blank is created through either gravity casting or hydraulic forging, followed by a sophisticated heat-treatment process in an automated implant. This ensures a refined material structure capable of handling the high stresses of high-performance internal combustion engines.
Precision Machining and Quality
The manufacturing process is completed on state-of-the-art CNC machinery utilizing diamond-tipped tooling. This allows for exact tolerances and specific surface finishes tailored to the requirements of your engine. Every piston undergoes rigorous manual and automatic quality control inspections to guarantee premium standards.
Enhanced Coatings for Longevity
To ensure optimal performance and engine protection, this piston features dual-layer coating technology:
- Molybdenum Bisulphite Coating: A specialized black finish that assists during the critical engine break-in period and significantly reduces friction during operation.
- Phosphate Coating: Borrowing from Formula One engine development, this all-over coating increases surface hardness and adds micro-porosity to the surface. This improves the adhesion of the Molybdenum coating, resulting in twice the coating durability and extended component life.
Key Features
- Grade C 54.21mm sizing for precision fitment
- High-strength, low-expansion alloy construction
- CNC machined for exact tolerances
- Friction-reducing Molybdenum Bisulphite surface treatment
