What You're Actually Buying
This is the plastic/composite hub cover that bolts over the front wheel end on Freightliner Cascadias and Volvo VNL/VNR trucks running the aerodynamic wheel package - not a decorative chrome cap, an actual aero piece that's part of the fuel economy spec on these trucks. Comes as a kit: cover, mounting hardware, sometimes a gasket or seal ring depending on the year.
It mounts to the hub face using the wheel-end bolt pattern, so it's specific to the axle and hub setup Freightliner/Volvo used - this isn't a universal snap-on hubcap you buy off a rack at the truck stop.
Kit runs $104, which is normal for these - they're not cheap because they're not a generic stamped steel cover, they're molded to spec for that wheel-end assembly.
How the Cross Numbers Line Up
The 74255-061 is the Freightliner/Volvo part number, and it crosses to A22-74255-040 and the ABP-N31-7425537 because these are all the same aero hub cover produced across different supplier batches - FlowBelow made a lot of these aero components under contract, so you'll see their numbers mixed in with the Freightliner OE numbers depending on which catalog you're pulling from.
FRCA-1602-SET is the aftermarket kit number some suppliers use for this exact application - same physical part, different part number because it's packaged by a different distributor.
What actually matters here: hub bolt spacing and cover diameter have to match your wheel end. These covers were used across a few years of Cascadia/VNL production and there were minor running changes, so don't just match by truck year - pull the number off your old cover or check your build sheet before ordering.
Ordering From Us
We keep these in stock in Tacoma and most orders that come in before early afternoon go out same day - if you're a fleet running the I-5 corridor or anywhere in the Northwest, that matters when a truck's sitting.
We ship nationwide too if you're not local - just give us the VIN or the number stamped on your old cover before you order so we're not guessing. These wheel-end pieces are specific enough that a mismatch means a return, and nobody wants that hassle.
Comes with our standard 6+ month warranty. If it doesn't fit or something's off with the kit, call us - we'd rather sort it over the phone than have you stuck with a part that doesn't bolt up.

Frequently asked questions
Does 74255-061 fit my 2019 Freightliner Cascadia?
Probably, but 'probably' isn't good enough for a wheel-end part - Freightliner ran a few variations of this aero hub cover through Cascadia production. Pull the number off your existing cover or check the VIN against the build spec before you order. Takes two minutes and saves you a shipping label back to us.
Is this the same as the FlowBelow ABP-N31-7425537 version?
Physically yes, it's the same hub cover - FlowBelow supplied a chunk of these under contract for Freightliner/Volvo's aero package, so their part number and the OE number both point to the same piece. Cross-reference it against your old part's number if you're not sure which one you had.
Does the kit come with the mounting hardware or do I need to source that separately?
The kit includes the mounting hardware - bolts and typically a gasket/seal ring depending on the application year. You shouldn't need to hunt down extra pieces, but if your old cover had additional brackets or spacers that aren't in this kit, give us a call before you install.
