Description

When compression drops or valve wear becomes a problem, the Polaris 500 engine needs more than a quick refresh. This Master Tech top end rebuild kit replaces the major wear components so the engine seals properly and runs strong again.

Because the cylinder, piston, valves, and timing components are replaced together, the rebuild restores proper combustion pressure and reliable valve timing. As a result, the engine delivers smoother performance and improved durability.

All components are backed by a 1-year REV6 parts warranty and are designed to meet OEM fitment standards.

THIS KIT INCLUDES

• New replacement cylinder assembly
• New cast OE-style replacement piston
• 2 Forged nitrite intake valves
• 2 Forged nitrite exhaust valves
• Complete top-end gasket kit
• Timing chain
• Timing tensioner
• High-temp valve stem seals
