A front differential does not usually fail quietly. It starts as a whine you tell yourself is tire noise, then a clunk on engagement, then one day you are in four-wheel drive in mud and the front wheels are just along for the ride. On a Ranger that is more than an inconvenience — the whole reason you own a full-size Ranger is that it pulls itself out of things. A front diff is also not a part you rebuild in an evening with a parts-store kit, which is why a complete replacement unit is often the honest answer. The 4XPRO Front Differential for the Polaris Ranger 1000 and Ranger EV is that replacement, and it runs $1,099.99.
The OEM numbers it replaces
This is the part of the listing to read twice, because Polaris used several different front differentials across these model years. 4XPRO lists this unit as replacing:
- 1334420
- 1334602
- 1334603
- 1336960
- 1336961
- 1336962
4XPRO's own instruction is blunt and worth repeating: verify the OEM number on your differential before ordering, since several differential options were used across model years. Their listing says it twice, which tells you how often it goes wrong. The number is on the housing. Get under the machine with a rag and a flashlight, find it, and match it against the six above before you spend eleven hundred dollars. "It's a 2022 XP 1000" is not enough information to buy a front diff.
Fitment
- 2021-2026 Polaris Ranger 1000 XP, all models
- 2021-2023 and 2026 Polaris Ranger 1000 full-size
- 2024 Polaris Ranger EV
Note the gap in the middle of that list. The XP 1000 runs straight through from 2021 to 2026, but the full-size Ranger 1000 is listed as 2021-2023 and 2026 — the 2024 and 2025 full-size years are not on the list. That is exactly the kind of break that happens when a manufacturer changes a part mid-run, and it is another reason the number on your housing matters more than the year on your title.
Why a complete unit instead of a rebuild
You can buy bearings and seals for these, and for a diff that is only weeping at a seal, that is the right fix — we sell those kits too. But once there is metal noise, a complete assembly starts making more sense than a teardown. A front diff that has been run low on oil or loaded hard in four-wheel drive has usually taken wear across the gearset, the sprague and the bearings all at once, and chasing it piece by piece turns into two weekends and a parts bill that gets uncomfortably close to a whole unit. A sealed assembly also means you are not setting preload or shimming anything on your garage floor.
The other argument is downtime. A Ranger that is a work machine does not get the luxury of sitting on jack stands while parts come in one at a time. Swapping a complete differential is a known job with a known end point.
Who it is for
This is for the owner whose front diff is already making noise, or who has decided the one in there is on borrowed time and does not want to find out where. It is also the part you want if you have been running big tires, heavy loads or a lot of four-wheel-drive mud, all of which shorten the life of the front end.
While it is out, do the rest of the job properly. Look at the front axles and their boots, check the prop shaft and the output seals, and fill the new unit with the correct fluid to the correct level before you call it done — a new differential run dry fails exactly as fast as an old one. And if you have not already found the reason the first one died, keep looking, because a replacement part does not fix a cause.
