Cylinder Works 2010 Polaris Ranger 800 4x4 800cc Standard Bore Cylinder Kit 10.2:1 Comp. 80mm

If you're rebuilding the top end of your 2010 Polaris Ranger 800 4x4, this standard bore cylinder kit from Cylinder Works is a solid option to get your engine running like new again. This kit is designed to replace your original cylinder and piston, bringing back lost horsepower and performance without breaking the bank compared to OEM parts.

The heart of this kit is the cast aluminum cylinder, which features a nickel silicon carbide (NSC) electroplate bore. This advanced plating allows for very tight tolerances, which means less friction as the piston moves up and down. That reduced friction not only helps with durability but also contributes to better performance. The bore is also precision diamond honed to exact dimensions, ensuring your piston rings seal properly against the cylinder wall. This precise finish is crucial for good oil retention, which keeps everything well-lubricated and reduces wear.

This kit comes with everything you need to get your engine back together, including the cylinder, a Vertex piston, and all the necessary gaskets. With a 10.2:1 compression ratio and an 80mm bore, it's built to restore your Ranger's power and responsiveness.
