Vertex 22520B Replica Piston Kit Bore - 53.94mm

The Vertex 22520B Replica Piston Kit delivers OEM-quality replacement performance with a precision 53.94mm bore. Engineered as a direct OE replacement, this complete kit provides everything needed for a professional rebuild of two-stroke or four-stroke engines.

Construction and Materials:

• Gravity cast aluminum alloy construction with 18% silicone content for optimal strength-to-weight ratio
• T-5 heat treatment hardening and tempering cycle for enhanced durability
• High-tech Molybdenum Disulphide coating on piston skirt reduces friction and accelerates break-in

Complete Kit Includes:

• Piston with precision 53.94mm bore
• OEM replacement piston rings (individual rings for two-stroke, complete set for four-stroke applications)
• Wrist pin
• Circlips

The Molybdenum Disulphide coating significantly reduces break-in time while extending piston life by minimizing friction and heat buildup during initial operation. This replica piston kit meets OEM specifications for fit and performance, making it an ideal choice for engine rebuilds requiring factory-equivalent quality.
