ProX Top End Gasket Yamaha Engine Seal Kit

The ProX Top End Gasket Kit (also sold as a top end gasket set or engine seal kit) for Yamaha engines has the sealing components you need for a top-end rebuild. Each kit is matched to its engine application, so you can order the right one by part number.

Key Features:

• Covers the top end, from the cylinder and head gaskets down to the smallest O-rings and rubber seals
• Built to ProX specifications for dependable sealing
• Made from advanced materials, including multi-layer steel and synthetic fiber blends, depending on the engine
• Gasket thicknesses and materials are chosen for each engine, which helps the gaskets seat cleanly without folding, bending, or tearing during installation
• Designed to complement ProX pistons and connecting rods
• One part number covers the whole top-end gasket set for the application

Whether you're doing routine maintenance or restoring an older engine, a ProX top end gasket kit helps stop leaks and restores sealing performance. Having the parts in one kit also saves time during the rebuild.
