6.4L Powerstroke

Doc's Diesel 6.4L Powerstroke Parts

Stay Ahead of It, and It'll Stay Ahead for You.

The 6.4L Powerstroke is the most honest engine Ford ever built: it tells you exactly what it wants, and it wants maintenance. The 2008-2010 twin-turbo trucks make serious power and pull like freight trains—and the owners who keep them happy are the ones who never let an interval slide. Clean oil, clean fuel, fresh filters, on time, every time. Doc's stocks everything that regimen requires, matched to the 6.4L specifically.

The Parts the 6.4L Actually Asks For.

Fuel filters and fuel/water separators lead the list—the 6.4L's fuel system rewards clean fuel like few engines ever made—alongside oil filters, engine air and cabin air filters, complete filter kits, heavy-duty oil, and treatments for lubricity and injector cleanliness. Everything built for the 2008-2010 Super Duty trucks.

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

Every part meets or exceeds OEM design, fit, and function and is backed by the Fitment Guarantee: doesn't fit, we make it right. No guesswork. No BS.

Doc's Makes It Easy.

Grab your fitments through the Vehicle Selection Tool, then run the tight schedule: oil every 5,000, fuel filters every 5,000 to 10,000, and don't stretch either. On a 6.4L, maintenance done early is always cheaper than maintenance done late.
