RAM EcoDiesel Parts

Keep the Torque. Skip the Dealership.

The EcoDiesel RAM 1500 is the thinking man's half-ton. You bought it for the diesel torque that makes a loaded bed feel empty, the towing manners a gas 1500 can't fake, and fuel economy that turns long hauls into cheap ones. The trade? The 3.0L EcoDiesel expects to be maintained like a diesel—clean oil on schedule, clean fuel always, and filters that actually seal. This collection is every EcoDiesel maintenance part Doc's builds for your RAM—filters, complete kits, oil, and treatments matched to your exact model year—so you can do the work in your own driveway, skip the dealership markup, and keep that diesel earning its keep.

Everything Your EcoDiesel RAM Needs, In One Place.

We cover both generations of the diesel 1500: the 2014-2019 RAM 1500 3.0L EcoDiesel and the 2020-2025 RAM 1500 3.0L EcoDiesel. Inside this collection you'll find oil filters and fuel filters built for the 3.0L's high-pressure common-rail system, engine air and cabin air filters, complete filter kits that put a full service in one box, and oil change kits that pair the correct filter with the right full synthetic oil at the proper capacity. Round it out with Doc's diesel treatments—cetane boost for cold starts, injector cleaning between fuel filter changes, and anti-gel protection for winter—and your maintenance plan is covered from the fuel tank to the crankcase.

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

A modern common-rail diesel is only as reliable as the parts protecting it, and the EcoDiesel is no exception. Every filter and kit in this collection is engineered to meet or exceed OEM design, fit, and function—correct seals, correct media, correct fit, no modifications. That's the standard whether you're buying a single cabin filter or a complete maintenance kit. And with our Fitment Guarantee, if a part doesn't fit your RAM, we'll make it right. No guesswork. No BS.

Doc's Makes It Easy to Service Your RAM.

The fastest route to the right parts is our Vehicle Selection Tool—enter your year and model, and we'll show you exactly what fits your EcoDiesel, from a single fuel filter to the full-service kit. One important heads-up: the 2014-2019 and 2020-2025 trucks run different generations of the 3.0L, and their filters are not interchangeable—shop by your specific year, not just the EcoDiesel badge. And since diesel RAMs often share a driveway with Cummins-powered 2500s and 3500s, double-check you're in the EcoDiesel collection before you order: same brand, very different engine.
