Cylinder Works High Comp Cylinder Kit Kawasaki Brute Force / Teryx 750 Cylinder Works High Compression Kits serve as high-performance cylinder upgrades, upping compression and addressing cylinder wear issues. Complete with brand-new OEM replica piston(s) featuring the same bore but with changes to raise compression. For a quick overhaul you will find cylinder(s), rings, gaskets, and all necessary hardware in the box. Vertex heat treated, T-5 hardened piston(s) are included in the kit. Depending on factory spec they will either be tempered cast or forged and feature molybdenum disulphite skirts. Coupled with the diamond honed cylinder sleeves, to ensure precise bore dimensions and optimal surface finish, this combination provides effective ring seal and oil retention.
