Vertex pistons are manufactured using Low-Ex aluminum alloys with 12%, 18%, or 21% silicon. They are produced using gravity casting or hydraulic forging, followed by heat treatment for material refinement. Machining is performed with CNC machines and diamond tools to achieve specific surface finishes. Every piston undergoes manual and automatic quality control. Vertex pistons feature a Molybdenum Bisulphite black coating for break-in and friction reduction, and a Phosphate Coating for improved adhesion and durability. This piston is 66.37mm with twin rings.

FULL DESCRIPTION

High Performance Grade C Twin Ring Piston

Upgrade your engine reliability with this premium Vertex replacement piston. Engineered for precision and longevity, this Grade C piston features a 66.37mm diameter and a twin ring design to provide optimal compression and consistent power delivery throughout the RPM range.

Advanced Material Technology

Vertex pistons are constructed using exotic Low-Ex (low expansion) silicon-charged aluminium alloys. Through a combination of gravity casting or hydraulic forging and a sophisticated heat-treatment process, these pistons achieve superior material density and structural integrity, ensuring they withstand the rigors of high-performance use.

Precision Engineering and Coatings

Every piston is machined using state-of-the-art CNC technology and diamond tooling for exact tolerances and specific surface finishes. To ensure maximum durability, this piston includes:

  • Molybdenum Bisulphite Coating: A specialized black coating that aids in the break-in process and significantly reduces internal friction.
  • Phosphate Coating: Borrowing technology from Formula One engines, this all-over coating increases surface hardness and provides light porosity for superior Molybdenum adhesion, effectively doubling the durability of the protective layer.

Key Features

  • Grade C sizing at 66.37mm
  • Twin ring configuration for enhanced sealing
  • High-tech heat treatment for refined material structure
  • Rigorous manual and automatic quality control inspections
  • Designed for reduced friction and extended component life
