Whether you're exploring the backwood trails or navigating a rocky mountain pass, the last thing you should be worrying about is damaging your radiator. Grizzz-Tek Radiator Guards offer great protection from rocks, mud, sticks and debris that can foul the fan or damage the radiator. You want your machine to work hard and play hard. Excessive heat in the cooling system can ruin a day on the trail or worse an engine; keeping the mud and trail dirt out of the radiator means you'll run cooler temps.
