The VERTEX Race GP Style Top End Kit is engineered for durability and performance, featuring pistons that undergo a T-5 hardening and tempering cycle to ensure structural integrity under high-stress conditions. To optimize initial operation and extend component longevity, all piston skirts are finished with a high-tech Molybdenum Disulfide coating, which facilitates faster break-in times while reducing wear. This comprehensive assembly includes OEM replacement rings, pins, circlips, and top end gaskets, ensuring precise fitment and reliable sealing within the engine.
Designed as a complete solution for top-end maintenance, the kit bundles all necessary hardware, including the piston, rings, pins, and circlips. Depending on the specific application, the package also incorporates either a wrist pin bearing or a cam chain, providing a streamlined approach to rebuilding the upper engine section. By combining heat-treated components with specialized low-friction coatings and genuine OEM replacement parts, this kit delivers the precision and consistency required for competitive racing and high-performance street applications.
