1989-2007 5.9L 24V Cummins

Doc's Diesel 1989-2007 5.9L Cummins Parts

Eighteen Years of 5.9Ls. One Place for Parts.

For eighteen years, the 5.9L Cummins was the engine that built the diesel pickup's reputation—from the mechanical first-gen 12-valves through the P-pumped legends to the common-rail 24-valves that closed out the run in 2007. Every era has its personality, and every era is still out there working. This collection is Doc's complete 5.9L coverage: whichever generation sits in your driveway, the maintenance parts that fit it are here.

Every Generation, Covered.

Oil filters, fuel filters, engine air and cabin air filters, filter kits, heavy-duty diesel oil, and fuel treatments—organized by year range so a first-gen owner and a common-rail owner both land on the right parts. The 5.9L family changed a lot across eighteen years, and the filters changed with it; this collection sorts it so you don't have to.

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

Everything meets or exceeds OEM design, fit, and function, backed by the Fitment Guarantee: if it doesn't fit your Cummins, we'll make it right. No guesswork. No BS.

Doc's Makes It Easy.

With this many year ranges under one engine badge, the Vehicle Selection Tool is your friend—enter your exact year and we'll show only the parts built for your truck. Twelve-valve and 24-valve parts don't interchange, and neither do the fuel systems across eras.
