    Currentness: these crosses come from Fleetguard's 2012 list and have not been revalidated as current. MK1451 was not found in our parse of Baldwin's 2024 list.

    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.
