What This Panel Is
This is the perforated aluminum walking surface that sits in the side fairing step area on a Cascadia. Silver aluminum finish, non-notched outline. It is the surface a driver puts a boot on every time they climb in or out, which is why it takes more abuse than almost anything else on the exterior of the truck.
The non-notched design means the panel edge runs straight, with no cutout for surrounding fairing hardware. Other tread versions in this family are notched and carry different mounting arrangements. That difference is the single most common reason a replacement panel shows up and will not drop in, so it matters more than the finish or the perforation pattern.
The listing covers one tread step panel. Fasteners, fairing structure, and the step box itself are separate. If the panel is damaged, inspect what is behind it before you order, because a bent panel usually means something underneath took a hit too.
Why These Numbers Cross
The headline reference is 22-68079-000. The related numbers 22-68079-002 and 22-68079-003 share the same base family and cover tread step panels in the same side fairing step location. They are listed here for identification only — we are not affiliated with, endorsed by, or authorized by any original equipment manufacturer, and these numbers are published so you can match what is stamped or tagged on your old part.
Shared base numbers in this range typically indicate the same application area with revisions to shape, notch configuration, or mounting hole layout. A dash suffix change is not cosmetic on a step panel. It can mean a notch was added or the fastener pattern moved, and either one changes whether the panel sits flat in the fairing.
Treat the cross-reference as a starting point, not a fitment guarantee. Pull the old panel, read the number on it, and compare overall length, outline, and mounting hole spacing against this aftermarket part. If the old panel is gone entirely, confirm the configuration by VIN before you commit.
How These Fail
Aluminum tread panels fail from fatigue and impact, not corrosion. Repeated step loading works the panel around the fastener holes until the holes elongate and the panel rattles or lifts at a corner. Once a corner lifts, it catches on boots and bends further. Road debris, curb strikes, and tire chain contact crack the perforated section outright.
Before ordering, check the fastener holes in the fairing structure behind the panel. If those are torn or the backing is deformed, a new panel alone will loosen again. Also look at the panel's outline against the fairing opening — a notched opening will not accept a non-notched panel, and forcing one in puts the load back on the fasteners.
22-68079-000 Cross-Reference & Interchange Numbers
These manufacturer and aftermarket numbers commonly cross-reference to 22-68079-000. 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
How do I tell if I need the non-notched version?
Pull the old panel and look at its outline. A non-notched panel has a continuous straight edge with no cutout for surrounding fairing hardware. If your old panel has a notch cut into one edge, this is not the right configuration. When the old panel is missing, confirm by VIN before ordering.
Does 22-68079-000 cross to 22-68079-002 or 22-68079-003?
Those numbers are in the same base family and cover tread step panels for the same side fairing step area. They are listed for identification only. Suffix differences in this range can reflect notch shape or mounting hole changes, so compare length, outline, and hole spacing against your old part before you order.
Is this sold as a pair or one panel?
This listing covers one tread step panel. If you are replacing both sides of the truck, or multiple steps on one side, order accordingly. Check each panel individually, since the driver side often wears faster than the passenger side and the two positions may not use the same configuration.
