Polaris Ranger & Sportsman 700 Complete Top End Rebuild Kit

Scored cylinder walls, low compression, or piston damage often require more than a simple piston replacement. This kit includes a new cylinder, standard piston kit, and top-end gasket kit, making it a smart choice when the cylinder has reached its wear limit but the valves can still be reused.

Replacing the cylinder and piston together helps restore compression, improve ring sealing, and gives your rebuild a fresh starting point.

What This Kit Includes

• Cylinder
• Top End Gasket Kit
• STD Piston Kit

When Is This the Right Kit?

Choose this kit if your cylinder has excessive wear, scoring, or damage that prevents it from being reused. However, if your valves still seal properly and meet factory specifications, you can reuse them and avoid replacing additional cylinder head components.

• New replacement cylinder.
• Standard piston kit.
• Top-end gasket kit included.
• Built for engines with reusable valves.

Replace Worn Components Before They Cause More Damage

A worn cylinder won’t properly support a new piston or rings. Replacing both at the same time helps restore compression, improves oil control, and gives your rebuilt engine the foundation it needs for dependable performance. Every REV6 Complete Top End Rebuild Kit includes a 1-year warranty.
