Description
If you’re running a Polaris RZR 900 and want measurable gains in displacement and compression ratio without extensive machine work, the Cylinder Works High Compression Big Bore Kit delivers the displacement increase and reliability you need. This bolt-on upgrade replaces your factory cylinder with a precision-engineered big bore assembly, gaining you cubic centimeters and horsepower while maintaining OEM fitment. You’ll get the extra power for trail riding and competition without the downtime or fabrication costs of a custom build.
The kit ships complete with everything needed for installation—no machine work, no re-plating required. Vertex pistons and Nickel Silicon Carbide plating ensure durability under sustained high RPM use, while the direct bolt-on design means you’re back on the trail in hours, not days.
