Complete Filter Kits

Doc's Diesel Complete Filter Kits

Every Filter. One Box. Zero Excuses.

Every filter on your truck exists to sacrifice itself for something more expensive—and every one of them is easiest to change when you change them together. Doc's Complete Filter Kits are built on that simple idea: one box with every filter your service calls for, matched to your exact truck, so the full refresh happens in one afternoon instead of dragging across three orders and a parts-store run you kept putting off.

The Whole Lineup, Matched and Boxed.

Depending on your truck's configuration, kits bundle the fuel/water separator, fuel filter, oil filter, engine air filter, and cabin air filter—each one the same OEM-spec Doc's filter you'd buy individually, priced better together. No cross-referencing five part numbers, no discovering the air filter you forgot after the truck's back together.

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

Every filter in every kit meets or exceeds OEM design, fit, and function, keeps your factory warranty intact when installed correctly, and is covered by the Fitment Guarantee: if anything in the box doesn't fit, we make it right. No guesswork. No BS.

Doc's Makes It Easy.

Enter your year, make, and model in the Vehicle Selection Tool and we'll show the exact kit for your truck. Then follow the intervals on each filter—fuel every 5,000-10,000, oil every 5,000-7,000, air every 5,000-10,000, cabin every 15,000—or simplify life and refresh the set together on the tightest one.

Free Shipping on All U.S. Orders $99+

One kit typically clears the free shipping line on its own—everything over $99 ships free anywhere in the U.S. Every filter. One box. Zero excuses.
