Hot Cams 2017 Polaris Sportsman Touring 570 EPS Built Before 8-29 570cc Steel Exhaust Valve

This steel exhaust valve from Hot Cams is forged from a single piece of steel, which improves the grain flow for better mechanical strength. It's treated with a special Black Nitride coating (BrN) using PVD and CVD processes. This coating creates a very hard surface that also has low friction, helping to keep heat down and prevent carbon from building up on the valve. The valve head and seat surfaces are precisely machined, and the tip of the steel stem is hardened using induction heating. This valve is designed to work with your vehicle's original components.

This valve fits a range of Polaris vehicles, including models like the RZR 570, Ranger 570 EFI, and Sportsman 570. The precision machining on the valve head and seat ensures a good seal, while the hardened stem tip adds durability for the valve train's repetitive action. The Black Nitride coating is a notable detail that helps manage the harsh environment inside the combustion chamber.
