Fits: 2011 thru 2016 Chevy Silverado/GMC Sierra 2500HD/3500HD LML Duramax Diesel

Expertly designed to provide a leak-proof connection between the lower hose and radiator, the Duramax Lower Radiator Hose O-Ring guarantee a hassle-free replacement. GM does not offer this o-ring separately and only includes it with the lower radiator hose assembly which costs hundreds of dollars to replace. Say goodbye to unnecessary hose replacements and hello to a more efficient and cost-effective solution.
