What This Grille Actually Is
This is the roadside (curb side, opposite the control panel) grille cover for Thermo King Precedent series reefer units - S-600, S-700, C-600. It's the black plastic panel that covers the condenser/evaporator section and lets airflow through while keeping road debris out of the coil.
These crack from age, UV exposure, or getting clipped by a forklift or dock plate. Once the mounting tabs snap off or it's split down the middle, air doesn't flow right and you get warm coils fighting to keep temp.
Fitment is by unit series, not by year of truck, so don't go off what year your tractor is - go off what Thermo King unit model is bolted to the front of your trailer.
How The Cross Numbers Line Up
98-9117 is the Thermo King part number. You'll also see it stamped or listed as 37-98-9117 or TK98-9117 depending on which supplier catalog you're pulling from - same physical grille, just different prefix conventions between Thermo King's own numbering and how parts houses log it in their systems.
The main thing to check isn't the number itself, it's the mounting pattern and the tab locations on your old grille. Precedent units changed some hardware clip styles across production runs, so if your unit is on the older or newer end of the S-600/S-700/C-600 run, the tabs can sit slightly different even though the panel looks the same.
Rule of thumb: pull the number off your unit's data plate or off the back of the old grille if it's still readable, and match that against what we've got before you order. Saves a return shipment on a part this size.
Ordering From PartStop
We stock this one in Tacoma and can usually get it out same-day if you call before the truck leaves. If you're not local, it ships nationwide - just built to handle freight without cracking further in transit, which happens more than people think with plastic grilles.
This is a direct replacement for 98-9117, not a maybe-it-fits guess. But confirm by your unit's model plate or the old part number before you buy, especially if your reefer's had any hardware swapped over the years.
Comes with our standard 6+ month warranty. If something's off on fitment, call the counter before you start drilling new holes - we'd rather sort it on the phone than have you force a part that's not quite right.

Frequently asked questions
Does 98-9117 fit my Thermo King unit?
It fits Precedent S-600, S-700, and C-600 series units specifically. Check your unit's data plate for the model - don't go off the trailer year. If you're not sure, read us the model number off the reefer unit itself and we'll confirm before you order.
Is this the same as the TK98-9117 part I found listed elsewhere?
Yes, TK98-9117 and 37-98-9117 are the same grille under different supplier number formats - Thermo King's base number is 98-9117 and that's what actually cross-references. Just confirm the mounting tabs match your old unit since hardware clips shifted a bit across production runs.
How do I know if I need the roadside grille versus the curb side one?
Roadside is the side away from the control panel - typically the side facing traffic when the trailer's parked at a dock. If you're not sure which one cracked, pull the old part and check the number stamped on the back, or snap a photo and we'll match it up.
Not sure it fits? We check before you pay.
Run your VIN and we’ll match parts to your exact truck, or call the counter — a person who knows trucks verifies fitment by OEM number before the order ships. No wrong-box returns.
