Product Description

CUMMINS 3949562 OEM OIL PICKUP TUBE GASKET – RAM 5.9L/6.7L (2003–2018)

Genuine OEM sealing for your 5.9L / 6.7L ISB engine. The Cummins 3949562 oil pickup tube gasket — also known as the oil suction pipe flange gasket — ensures a factory-spec seal between the oil pickup tube and the oil pump/block. This precise fit prevents oil leaks, aeration, and potential oil starvation that can risk bearings and turbo life. Made from genuine Cummins-specified materials and geometry for long service life. Ideal for maintenance, rebuilds, or anytime the oil pan or pickup tube is removed. OEM quality, direct-fit, and time-proven reliability for 2003–2018 Ram 2500/3500 with 5.9L or 6.7L Cummins engines.

Fitment Details:
• 2003–2007 Dodge/Ram 5.9L ISB (24-valve common-rail)
• 2007.5–2018 Dodge/Ram 6.7L ISB (24-valve common-rail)
Confirm by VIN/ESN before ordering, especially for chassis-cab or off-road applications. 

Cross Reference: Mopar 5086856AA (05086856AA) — equivalent OE Chrysler/Ram gasket number.
