The VERTEX Cast Race Top End Kit is engineered around a gravity cast aluminum alloy piston featuring 18% silicone content, a composition that delivers an exceptionally light yet robust structure. To optimize durability and performance, every piston skirt is finished with a high-tech Molybdenum Disulfide coating, which facilitates faster break-in times and extends overall piston life. The components undergo a rigorous T-5 hardening and tempering heat treatment cycle to ensure consistent mechanical integrity under race conditions.
This comprehensive top end assembly includes the piston, OEM replacement rings, pins, circlips, and top end gaskets, along with a wrist pin bearing or cam chain where applicable. By combining precise casting techniques with specialized surface treatments, the kit provides a reliable foundation for high-performance applications. The inclusion of OEM replacement rings ensures proper sealing and fitment, making this a complete solution for maintaining peak engine efficiency.
