This billet aluminum front cover is designed for 2003 - 2018 Dodge Ram trucks with 5.9L or 6.7L Cummins engines. When installing, keep in mind that the factory Cummins front crank seal isn't included, so you'll need to get it separately. Also, make sure to use the Cummins crank position sensor 5594275 and a Cummins gear housing gasket between the gear housing and block. For maintenance, just keep it clean and check the ARP 12 - point head stainless bolts regularly to ensure they're tight.
