What The 201SS Is
The 201SS is a bolt-on front deer guard built from stainless steel. It mounts to the factory frame mount points on the 2008-2017 Cascadia, old body style. No drilling, no welding, no cutting into the bumper. The install is fully reversible, which matters on a leased truck or a unit headed back to a dealer at end of term.
Construction is 2mm steel, with 304 stainless on the premium builds. The polished stainless finish handles road salt, chip seal spray, and washdown chemicals without peeling or rusting through the way a painted tube guard does once the coating gets stone-chipped. That is the main reason fleets running winter lanes spec stainless over powder coat.
The job of the guard is simple: take the hit so the hood, headlamps, and radiator core support do not. A deer strike at highway speed on an unguarded Cascadia usually means a hood, a grille, at least one headlamp assembly, and a day or two of downtime. The guard absorbs and spreads that load into the frame horns.
Why 201SS And FIT-020FS33 Match
201SS and FIT-020FS33 describe the same physical guard. Same stainless material, same tube layout, same mounting bracket spacing to the Cascadia frame horns. The two numbers exist because suppliers catalog deer guards differently: one uses a short material-suffix code, the other a longer fitment-prefixed SKU. The hardware in the box does not change.
When you cross deer guards, the numbers only line up if three things match: body style generation, bracket bolt pattern at the frame, and overall guard width relative to the bumper face. All three are the same across these two numbers for the old body style Cascadia. That is what makes it a real cross rather than a rough visual lookalike.
These numbers are listed for identification only. PartStop LLC is not affiliated with, endorsed by, or authorized by any OEM. Cross-reference is a starting point, not a fitment promise. Confirm by VIN or by reading the number stamped or tagged on the guard and brackets you are pulling off.
Check Before You Order
Confirm body style first. The 201SS bolts directly to the 2008-2017 Cascadia, old body style. It will also go on the 2018-2025 new body style Cascadia, but only with a conversion bracket. It does not bolt straight to the newer trucks. If you order for a new body style truck without the bracket, the guard will not mount.
Then look at what is behind the bumper. If the truck has already eaten a deer, the frame horn mounting tabs may be bent, cracked, or elongated at the bolt holes. A new guard bolted to a distorted mount will sit crooked and work the fasteners loose. Straighten or repair the mounts first, and replace stretched hardware rather than reusing it.
201SS Cross-Reference & Interchange Numbers
These manufacturer and aftermarket numbers commonly cross-reference to 201SS. 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 the 201SS fit a 2020 Cascadia?
Not directly. The 201SS is designed to bolt to the 2008-2017 old body style Cascadia frame mounts. It can be fitted to the 2018-2025 new body style, but a conversion bracket is required. Verify your body style by VIN before ordering.
Do I need to drill or weld to install this deer guard?
No. On the 2008-2017 old body style Cascadia it uses the factory frame mount points, so the install is bolt-on and reversible. Inspect those mounts for prior impact damage before you hang the guard. Bent or elongated tabs will throw the guard out of alignment and loosen fasteners over time.
Is FIT-020FS33 the same part as 201SS?
Yes, those two numbers refer to the same stainless steel Cascadia deer guard, catalogued under different supplier numbering schemes. The material, tube layout, and bracket spacing are the same. Treat the cross as a starting point and confirm against the number on your existing guard or by VIN.
