Product Details

Brian Crower offers these stainless steel exhaust valves specifically for the 2021 and newer Polaris Pro R. These valves are a +1mm oversize, measuring 30.2mm in diameter, which can help improve flow when rebuilding or upgrading your engine's top end.

Crafted from durable stainless steel, these valves are built to withstand the heat and stress of continuous operation. The +1mm oversize design means they are slightly larger than stock, allowing for a potentially improved seal and better cylinder filling when paired with appropriate porting or tuning. This is a popular choice for those looking to get the most out of their Pro R engine during a rebuild.

When installing these valves, ensure your valve seats are properly prepared to accommodate the slightly larger diameter for optimal performance and sealing. Always refer to the manufacturer's installation guidelines for specific details.
