What 56499005 Actually Is
The 56499005 is the mounting bracket that carries a deer guard on the front of a Kenworth T680 or T880 built 2018 through 2024. It is not the guard tube itself. It is the steel structure between the factory frame mount points and the guard, and it is the part that takes the load when something hits the front of the truck.
Construction is steel, finished in a neutral gray that sits behind the bumper opening without drawing attention. Wall thickness on this style of bracket runs around 2mm, with stainless used on some premium versions. The finish is there to keep road salt and chip damage from turning into rust-through at the weld seams and bolt holes.
It bolts to existing frame mounting locations. No drilling, no welding, and the install is reversible if the truck goes back to a fleet spec that does not run a guard. Category-wise it lives with steel and chrome bumper hardware, not with trim.
Why These Numbers Cross
56499005 and FIT-016AS33 describe the same bracket geometry. The numbers differ because they come from different catalog systems, not because the hardware is different. What makes two bracket numbers interchangeable is the bolt pattern at the frame end, the standoff distance forward of the bumper, and the mounting face that the guard clamps to.
If all three of those match, the parts cross regardless of what the label says. That is the case here. FIT-016AS33 is listed for identification only so you can match a number stamped or tagged on the part you pulled off. We are not affiliated with, endorsed by, or authorized by Kenworth or any other manufacturer.
Treat the cross-reference as a starting point, not a fitment guarantee. Confirm by VIN or by reading the number off the old bracket before you order. Trucks in the 2018-2024 range have seen bumper and mount revisions, and a fleet unit may have been rebuilt with hardware that does not match its build sheet.
Failure Modes And Checks
Brackets fail three ways. A direct animal strike bends the arms rearward and cracks the weld at the frame plate. Long-term vibration elongates the bolt holes until the guard develops a shake at highway speed. And salt corrosion eats the lower plate where water sits after a wash, usually showing as bubbling under the finish before it opens up.
Before ordering, pull the guard and look at both frame mount plates. If the holes are oval or the frame rail itself is deformed, a new bracket alone will not fix the rattle. Check that the guard tube is still straight too, because a bent guard loads a fresh bracket unevenly and cracks it again.
56499005 Cross-Reference & Interchange Numbers
These manufacturer and aftermarket numbers commonly cross-reference to 56499005. 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
Does 56499005 include the deer guard itself?
No. 56499005 is the bracket that mounts the guard to the truck. The guard tube or grille structure is a separate part. If your guard is bent from an impact, inspect it before reinstalling, because a distorted guard will put uneven load on a new bracket.
Is FIT-016AS33 the same part as 56499005?
They cross to the same bracket. The numbers come from different catalog systems. Use FIT-016AS33 to identify what you pulled off the truck, then confirm fit by VIN or by matching the number on the old bracket before you order.
Do I have to drill anything to install it?
No. The bracket bolts to factory frame mount locations on the T680 and T880, so no drilling or welding is needed and the install is reversible. If your holes do not line up, the truck may have been rebuilt with non-standard mounts. Verify against the old part before proceeding.
