Upgrade and protect your Chevy/GMC 6.6L Duramax (2001–2010 LB7/LLY/LBZ/LMM) with the Melling M561 oil pump, the factory-replacement solution that supersedes the M316. Featuring a modern gerotor design for superior oil priming, consistent flow, and high RPM durability, this pump keeps even tuned and hard-working diesels lubricated mile after mile.
The M561 delivers OE-standard volume and pressure, with billet steel gears and a heavy-duty manganese phosphate-coated housing for extra protection in severe conditions. Installation is bolt-on with the factory timing set—no special adapters required. Suitable for both daily drivers and performance applications, it’s the trusted upgrade for stock, rebuilt, or mild performance Duramax engines.
