OEM engine oil drain plugs on Dodge Ram Turbo Diesel trucks are known to develop fractures. Although the original design idea is good - a flush plug that gives maximum ground clearance - the thin shoulder of the plug can give-way if torqued too tight. The plug has a 1" hex head. We're pleased to be able to offer this heavy-duty replacement drain plug for your application. It's made from stainless steel, is magnetic, and comes with one alumimum sealing washer.
