FULL DESCRIPTION
Vertex 55.95mm Single Ring Replica Piston
Restore your engine performance with this premium Vertex +2.00mm oversize replacement piston. Engineered for durability and precision, this piston is designed to meet or exceed original equipment specifications, providing a reliable solution for your engine rebuild.
Advanced Manufacturing and Material Quality
Vertex pistons are crafted using high-quality Low-Ex silicon-charged aluminium alloys, with silicon content ranging from 12% to 21% depending on the specific application requirements. These pistons are produced via precision gravity casting or hydraulic forging, followed by a sophisticated, automated heat treatment process. This refined material structure ensures maximum strength and thermal stability under high-stress operating conditions.
Precision Engineering and Coatings
Utilizing state-of-the-art CNC machinery and diamond-tipped tooling, Vertex achieves exceptional dimensional accuracy and specific surface finishes. To enhance longevity and performance, this piston features dual-layer protection:
- Molybdenum Bisulphite Coating: A specialized black coating that assists during the critical engine break-in period and reduces friction within the cylinder walls.
- Phosphate Coating: Borrowed from Formula One engine technology, this layer provides a slight increase in surface hardness and creates a light porosity that ensures superior adhesion of the Molybdenum coating, effectively doubling its durability.
Key Features
- +2.00mm oversize (55.95mm diameter) for precision cylinder boring
- Single ring design for optimized performance
- High-tech heat treatment for structural integrity
- Advanced friction-reducing surface treatments
- Rigorous manual and automatic quality control inspections
