Product Details

The Cummins Fleetguard LF3970 is a full-flow spin-on lube oil filter engineered for Cummins ISB and QSB diesel engines. Manufactured to Cummins OEM specifications, this filter delivers reliable oil filtration to protect critical engine components during every service interval.

At the heart of the LF3970 is Stratapore multi-layer filter media, which achieves 98.7% filtration efficiency at 30 microns, capturing harmful contaminants before they can cause wear on bearings, cylinder walls, and other precision engine parts. The filter is a no-bypass-valve (BPV = 0 PSI) design intended for commercial and industrial Cummins engine applications.

Key Specifications:

  • Filter Type: Full-flow spin-on lube/oil filter
  • Overall Height: 6.96 in (176.78 mm)
  • Largest OD: 3.68 in (93.47 mm)
  • Seam OD: 3.67 in (93.22 mm)
  • Gasket OD: 2.83 in (71.88 mm)
  • Gasket Inside Diameter: 2.46 in (62.48 mm)
  • Thread Size: 1-1/8–16 UN-2B
  • Filtration Efficiency: 98.7% TWA at 30 microns (Stratapore media)
  • Bypass Valve (BPV) Setting: None (0 PSI)
  • Standpipe: No

OEM & Cross-Reference Part Numbers:

  • Cummins: 3937144, 3937736, 3942365, 5404947
  • Baldwin: B7177, BT595
  • Donaldson: P550428, P551019
  • Wix: 57182
  • Volvo: 14406393

The LF3970 is the correct oil filter for commercial truck and industrial Cummins ISB/QSB applications. Note: Dodge/Ram pickup truck applications requiring a bypass valve should use the LF3972 instead. Always verify your engine serial number and configuration before ordering.
