5.0L Cummins

Doc's Diesel 5.0L Cummins Parts

Nissan Moved On. Doc's Didn't.

The 5.0L Cummins in the 2016-2019 Titan XD was the truck world's great what-if—a genuine Cummins V8 in a heavy-half-ton package that earned a loyal following before Nissan pulled the plug. If you own one, you already know the story: the truck is excellent, and the parts support keeps getting thinner everywhere you look. Not here. Doc's stocks the maintenance parts that keep the 5.0L working, because a discontinued badge doesn't mean a discontinued truck.

Full Support for the Titan XD.

Oil filters, fuel filters and fuel/water separators, engine air and cabin air filters, complete filter kits, heavy-duty diesel oil, and fuel treatments—all matched to the 2016-2019 Titan XD 5.0L Cummins. The same OEM-spec standard we hold for every Cummins, applied to the one everybody else forgot.

Built to OEM Specs. Backed by the Doc's Fitment Guarantee.

Every part meets or exceeds OEM design, fit, and function and carries the Fitment Guarantee: if it doesn't fit your Titan, we'll make it right. No guesswork. No BS.

Doc's Makes It Easy.

Run your year through the Vehicle Selection Tool and stock up while you're here—owners of orphaned platforms know the smart move is a shelf with a spare service on it.
