    Source: Baldwin Manufacturers' Cross-Reference, Form 560-24 (2024). Baldwin's published direction is manufacturer part → Baldwin replacement. This list shows what Baldwin published in 2024. It does not verify that the numbers interchange today.

    Upgrade chains run one way: equipment spec'd with a newer filter number should not step back to the older one. Go by what the truck was spec'd with.

    Always verify against the current OEM catalog before ordering. Cross references are a starting point, not a guarantee of fit.
