Fleetguard Oil Filter Cross Reference (Heavy Duty Guide)

A Fleetguard oil filter cross reference converts an LF part number into the equivalent Baldwin, Donaldson, WIX or FRAM number for Cummins, Detroit Diesel, Volvo, Mack or Caterpillar engines. Fleetguard is no longer a Cummins-owned brand: it belongs to Atmus Filtration Technologies, spun off as an independent public company in 2023.

That ownership change matters less than one specific catalogue error this guide found while checking two of the most common LF numbers against each other.

Who Makes Fleetguard Filters?

Fleetguard filters are made by Atmus Filtration Technologies, a standalone, publicly traded company founded by Cummins in 1958 and independent since 2023. Cummins does not manufacture Fleetguard filters anymore; it simply recommends them.

Cummins' own parts page confirms the current arrangement in its own words: it "recommends Fleetguard filtration products by Atmus Filtration Technologies." That is a recommendation relationship, not ownership.

This is an easy detail to get wrong, because the brand carried the Cummins name internally for decades first. Fleetguard Inc. had been a Cummins business unit since 1958, renamed Cummins Filtration in 2006 as part of a branding consolidation, while continuing to sell filters under the Fleetguard product name the whole time. The 2023 Atmus IPO is a separate, later event: the point where Fleetguard stopped being a Cummins subsidiary at all.

Atmus runs nine manufacturing operations and five technical centers worldwide, headquartered in Nashville, Tennessee. The exact list of individual plant cities is not published on Fleetguard's own site in a form this guide could confirm, so treat any specific plant-by-plant claim you see elsewhere as unverified against that count.

How to Read a Fleetguard Part Number

Fleetguard uses a two-letter prefix to identify the filter type, then a digit string, then sometimes a suffix for the media technology.

What does LF mean?

LF is the lube filter prefix. Fleetguard's official Cross Reference Guide organizes its whole catalogue by these prefixes: LF for lube, FF for fuel, FS for fuel/water separator, AF for air, HF for hydraulic and WF for water/coolant. Seeing "LF" on a filter tells you it is an oil filter before you read another digit.

Do the digits encode the filter's size or specs?

No confirmed pattern exists. Fleetguard's own technical article on identifying an oil filter explains filtration types and media categories but never explains how the numeric portion is assigned. No Fleetguard document states outright that the numbering is arbitrary, but none demonstrates a system either, so treat adjacent numbers as unrelated until the catalogue says otherwise. This is the same caution that applies to Donaldson's P-prefix catalogue, where digits are also catalogue positions rather than specifications.

What does the NN suffix mean?

NN stands for NanoNet, Fleetguard's most advanced media, built from continuous nanofiber layers. It typically pairs with StrataPore as a second stage for higher efficiency and capacity than StrataPore alone. LF14000NN is the clearest example: a StrataPore-plus-NanoNet combination filter built for Cummins ISX and X15 engines.

What Is StrataPore Media?

StrataPore is Fleetguard's proprietary multi-layered synthetic filter media, developed in-house to improve on standard cellulose media in both efficiency and capacity.

A real spec sheet for the StrataPore filter LF3481 puts numbers behind that claim: 98.7% primary particle efficiency tested to ISO 4548-12, a rated flow of 30 liters per minute, and a minimum hydrostatic burst rating of 1,500 kPa. That 98.7% figure is not a marketing round number. Fleetguard's own filter ratings article explains it directly: a historical "absolute rating" meant capturing 74 of 75 particles at a given size, which works out to exactly 98.7%.

That same article is worth reading before trusting any micron number on any brand's oil filter. Fleetguard states plainly that a micron rating by itself is meaningless. It needs an efficiency value attached, because a filter can be rated at a given micron size while only catching half the particles that size or 99.9% of them, and the number alone does not say which.

Fleetguard Oil Filter Cross Reference Chart

This chart comes from Fleetguard's own Cross Reference Guide PDF (document LT36289-Rev 4), cross-checked against Baldwin's own Quick Cross-Reference form. Where the two disagree, both numbers are shown rather than picking one.

Luber-Finer equivalents from the same official guide: LFP3000 for LF3000, LFP9001XL for LF14000NN. Luber-Finer's field is blank for LF9009 in Baldwin's own chart, which is worth knowing before you go looking for one.

The Chart Error This Guide Found: LF9009 Is Not LF3000

LF3000 and LF9009 look like they should be interchangeable. Both are roughly 11.88 inches tall, both use a 2¼-12 UNS-2B thread, both share nearly identical outer and gasket diameters. A popular consumer cross-reference aggregator lists Donaldson P553000 as a valid match for LF9009.

It is not. Baldwin's own manufacturer PDF puts P553000 against LF3000 and BD103, and gives LF9009 a completely different Donaldson number: ELF7300, paired with Baldwin BD7309.

The two Fleetguard filters are not interchangeable despite the matching dimensions. LF9009 is the newer combination filter, built with a Venturi-nozzle bypass stage engineered specifically to replace LF3000 in Cummins ISC, ISL, ISM, M11 and N14 applications. A distributor listing BD7309 as an "LF9009 upgrade of BD103" independently confirms the two are treated as distinct, successive parts rather than two labels for one physical filter.

Order Donaldson P553000 believing it is correct for an LF9009 application, and you get a filter built to the older LF3000/BD103 spec instead. On a heavy-duty diesel engine that is not a cosmetic mismatch, it is the wrong filter in the housing.

Neither LF3000 nor LF9009 carries a published distinct bypass valve pressure in Fleetguard's own spec feed. Both list as "0 kPa" or "no separate pressure valve," which is a different design than a simple spring-loaded bypass filter and is worth knowing before comparing bypass PSI figures across the Fleetguard lineup the way you might on another brand.

What Vehicles and Engines Use Fleetguard Filters?

Fleetguard's coverage runs across nearly every major diesel engine family, not just Cummins.

Cummins, the brand's namesake relationship, covers the widest range: 5.9L and 6.7L Cummins in Dodge Ram 2500 through 5500 pickups (LF16035), ISC 8.3L through N14 (LF9009 and LF3000), and the ISX/X15 heavy-duty line (LF14000NN).

Detroit Diesel gets direct Fleetguard coverage as well. A Kenworth dealer parts page states it plainly: "Through industry leading Fleetguard products, Cummins Filtration now provides integrated filtration system solutions for Detroit Diesel engines," covering the DD13, DD15 and DD16 engine families, despite Detroit Diesel being a competing engine brand under Daimler Trucks.

Mack, Volvo and Caterpillar each have dedicated sections in Baldwin's official cross-reference form, listing recognized Fleetguard equivalents for each brand's own filter numbers. LF3973 and LF17502 cover Mack applications; LF3654 and LF777 cover Volvo. Fleetguard's coverage of these platforms is real and manufacturer-documented, not just aftermarket guesswork.

Kubota and other agricultural fitment claims circulate widely online but were not confirmed against a manufacturer or dealer fitment chart in this research. Treat any specific Kubota-Fleetguard pairing as unverified until you can check it against Fleetguard's own catalogue or a dealer parts counter.

Does Fleetguard Have an Official Cross Reference Tool?

Not one built for a casual reader. Cummins runs a "Fleetguard Cross Reference" feature inside QuickServe Online, but that portal is dealer and technician facing and requires a login.

What is genuinely useful is the official PDF Cross Reference Guide, a static document anyone can open and search, covering air, water, fuel, fuel/water and lube filters with direct cross references to Baldwin, Donaldson, FRAM, Luber-Finer and WIX. It does not include NAPA Gold; no primary Fleetguard document with a NAPA Gold column turned up in this research, so treat any NAPA Gold number for a Fleetguard filter as third-party sourced rather than manufacturer-confirmed.

Fleetguard's live product search on its own site requires a browser to render, so whether it accepts a competitor's part number as a search input could not be confirmed here.

Frequently Asked Questions

Is Fleetguard still owned by Cummins?

No. Fleetguard is a brand of Atmus Filtration Technologies, an independent public company spun off from Cummins in 2023. Cummins now recommends Fleetguard filters rather than manufacturing them, though the two companies remain closely linked through decades of shared history.

What does the NN suffix mean on a Fleetguard filter?

NN stands for NanoNet, Fleetguard's nanofiber media technology, typically layered with StrataPore for higher efficiency and capacity than StrataPore alone. LF14000NN, used on Cummins ISX and X15 engines, is the most common example.

Is LF9009 the same filter as LF3000?

No, despite sharing nearly identical dimensions and thread size. LF9009 is a newer combination filter with a Venturi-nozzle bypass stage designed to replace LF3000, and the two cross to different Donaldson part numbers (ELF7300 versus P553000) in Baldwin's own manufacturer chart.

Does Fleetguard make filters for gasoline passenger cars?

Fleetguard's catalogue is built for diesel engines in trucks, agriculture, construction and heavy equipment, with Cummins, Detroit Diesel, Mack, Volvo and Caterpillar as its core coverage. It is not a passenger car gasoline-engine catalogue the way FRAM or WIX are.

Before You Order

Confirm your engine make and model before you shop by part number alone. Fleetguard's own catalogue and Baldwin's cross-reference form agree on most common numbers, but the LF3000-versus-LF9009 mix-up in this guide shows that a shared dimension is not proof of a shared application. When a chart gives you two different Donaldson, WIX or Baldwin numbers for the same Fleetguard part, that disagreement is worth a phone call to a distributor before you spin one on.
