Product Details
This Brian Crower exhaust valve is a single, 30.2mm (+1mm) component designed for 2021 and newer Polaris Pro R models. It's constructed from stainless steel, a material known for its strength and resistance to heat and corrosion, which is important for exhaust valve longevity under demanding engine conditions. This specific valve is a replacement or upgrade part, intended to fit precisely into the engine's valve train.
The +1mm sizing indicates this valve is slightly larger than the stock diameter, which can be beneficial for improving exhaust gas flow when rebuilding or modifying an engine's top end. Stainless steel construction helps ensure it can withstand the high temperatures and pressures found in the combustion chamber, contributing to reliable engine operation. This part is sold individually, so you'll need to order the correct quantity for your specific engine build.
