This Polaris RZR 900 Upgraded Cylinder Head fits 2018-2020 RZR 900 engines. It comes assembled with upgraded guides, forged valves, high-temp stem seals, cams, and modified cam caps for added top-end oiling.

What This Cylinder Head Includes

• REV6 upgraded manganese bronze valve guides
• Upgraded forged one-piece nitrated valves
• High-temp performance valve stem seals
• Modified cam caps for added oiling to the top end
• Cams included

Built with Better Head Components

The manganese bronze valve guides help retain size, move heat better, and support longer service life. Meanwhile, the forged one-piece nitrided valves are built for strength, performance, rev control, and long-term durability.

The included high-temp valve stem seals help with oil control during top-end service. Plus, the modified cam caps add oiling support where the cylinder head needs it most.
