Description

Polaris Ranger & Sportsman 700 Master Top End Rebuild Kit

Low compression, excessive oil consumption, or valve damage often means it’s time for more than a piston replacement. This Master Top End Rebuild Kit includes a new cylinder, forged piston, intake valves, exhaust valves, and top-end gaskets, making it the right choice when the entire upper end of the engine needs attention.

If the crankshaft and lower end remain in good condition, rebuilding the top end can restore engine performance without the expense of a complete engine overhaul.

What This Kit Includes

• Cylinder
• Top End Gasket Kit
• Moly Forged Piston
• (2) Intake Valves
• (2) Exhaust Valves

When Is This the Right Kit?

Choose this kit when the cylinder has excessive wear, the valves no longer seal properly, or the piston has been damaged. Replacing these components together restores compression and gives the cylinder head a fresh start while reusing a serviceable bottom end.

• New replacement cylinder.
• Moly forged piston.
• New intake and exhaust valves.
• Complete top-end gasket kit included.
