What This Bracket Does
The intermediate cab extender bracket is a structural mount inside the rear cab side extension assembly. It carries the middle section of the extender fairing, holding the panel at the right standoff from the cab wall so the fairing edge lines up with the sleeper and the roof cap. It is driver-side specific. The right-hand bracket is a separate component and does not interchange.
It is a molded part with defined mounting points shaped for the intermediate position in the stack. The profile matters as much as the bolt pattern. A bracket from a different position in the extender assembly may bolt up at one or two points and still leave the fairing sitting proud, twisted, or rubbing.
This listing covers the LH bracket only. If both sides took damage from the same backing incident or the same sleeper panel letting go, you order each side separately and confirm each one against the number on the old part.
How These Brackets Fail
Vibration is the usual killer. The extender fairing is a big panel in the airstream, and every mile of washboard road works the bracket at its mounting points. Cracks start at the fastener bosses and spread through the molded web. Once one bracket in the assembly lets go, the load shifts to the neighbors and they follow.
The other common cause is impact. Backing into a dock post, a trailer swing, or someone leaning on the fairing during a tire change will snap the bracket even when the outer panel looks fine. Pull the fairing and inspect before you condemn the panel itself.
Symptoms to check for: fairing panel that flexes or rattles at speed, a visible gap between the extender and the cab, fastener holes that have elongated, or a panel that will not pull back to the correct gap no matter how you torque it. Any of those means you are looking at the bracket, not the hardware.
Why These Numbers Cross
A22-73340-000 and A22-73340-00 refer to the same LH intermediate cab extender bracket. The difference is trailing-zero formatting. Depending on whether you are reading a parts catalog, a dealer invoice, a body shop estimate, or a label molded into the old part, the same base number shows up with a different number of digits in the suffix field. Different databases pad it differently.
When you search either form, you are chasing the same casting with the same mounting geometry and the same hand. Our part is an aftermarket direct replacement listed against that reference. The number is shown for identification only — we are not affiliated with or authorized by the vehicle manufacturer, and the reference does not imply any relationship.
A22-73340-000 Cross-Reference & Interchange Numbers
These manufacturer and aftermarket numbers commonly cross-reference to A22-73340-000. Use them to identify the part — then confirm the exact fit by VIN or the number stamped on your old unit before you order. An interchange is a starting point, not a fitment guarantee.

Frequently asked questions
Will this fit my Cascadia?
A cross-reference is a starting point, not a fitment promise. The extender assembly varies with cab and sleeper configuration, so confirm by VIN with a dealer parts counter or by reading the number stamped or molded into the bracket you are pulling off. If the old number matches and the bracket profile and mounting points match, you are in the right place.
Is A22-73340-00 a different part than A22-73340-000?
No. It is the same LH intermediate cab extender bracket written with a shorter suffix. Catalog systems pad the trailing digits differently, which is why both forms turn up in searches. Verify by comparing the bracket shape and mounting hole pattern against the part you removed.
Can I use this bracket on the passenger side?
No. This is the left-hand, driver-side bracket. The molded profile is handed, so the right-hand component is sourced separately. Mirroring a driver-side bracket to the passenger side will leave the fairing panel sitting at the wrong standoff and put load on fasteners that were never meant to carry it.
