Hi all. I am about to purchase a gates timing belt and water pump kit for my 2013 mn off evil bay and noticed different pricing for the same kit. On further inspection it appears it comes down to the rpm rating of the belt , 3000 rpm or 5000rpm . Can anyone shed light on what the oem belt rating would be please. Is the 3000 rpm belt the accepted norm? I find no specific answers in the searched threads. Thanks. Please ignore i have realised its a marketing ploy by a particular seller
