Vertex VTK22189B Cast Replica Top End Piston Kit - Standard Bore 53.94mm, Standard Compression fuel-air-snorkel-kits precision CNC-machined from 6061-T6 billetBore: 53. 94mm Compression: Standard Compression Sizing: Standard Bore All pistons are heat treated with a T 5 hardening and tempering cycle. All piston skirts are coated with a high tech molybdenum disulphite coating for faster break in time and increased piston life. Cast piston kits are gravity cast aluminum alloy (not forged) with 18% silicone content, which produces an extremely light but very strong piston. Forged pistons are forged from 2618
