On a Polaris RZR XP 1000, the axle almost always lets go at the same place: the splined stub shaft that plugs into the differential. This upgrade kit fixes the weak link instead of just replacing it. It swaps the output hubs in the front differential for bigger hubs that accept the larger XP Turbo-size axle, and includes two Rhino 2.0 axles with stub shafts 37% larger than stock. It's a combined axle and diff upgrade for 2018-2023 XP 1000 and XP 4 1000 models.
Why You'll Love It
- Upgraded differential output hubs increase the stub shaft size for added strength
- Complete output hub assemblies work with compatible OEM and our aftermarket differentials
- Steel hub construction with a sintered bronze bushing for durability
- 4340 chromoly axles with a proprietary heat treatment for strength and longevity
- Operates at high CV angles, keeping the joints cooler through demanding suspension travel
- Field- and lab-tested for extreme strength and endurance
Why the Stub Shaft Matters
The splined stub shaft is the weakest part of the stock RZR XP 1000 axle. Replacing the OEM hubs with bigger ones lets you use axles with a 37% larger stub shaft, so you can ride harder with far less risk of snapping one off inside the diff. That's a fix you can't get from a stronger axle alone.
Rhino 2.0 Axles Included
The kit comes with two Rhino 2.0 axles made to use the beefier hubs. They're already tough, with end-to-end chromoly construction, bigger shaft sizes and larger CV joints for better articulation. Paired with the larger stub shaft that only works with this hub upgrade, the front end becomes much harder to break.
Kit Includes
- (2) Rhino 2.0 axles
- Axle hub assembly
- Front diff fill and drain plugs
- All necessary front diff seals and O-rings
Who It's For and What Pairs Well

Installation Notes
Installation means opening the front differential to replace the output hubs, so plan on fresh seals and O-rings (included) and refilling the diff with the correct fluid. Drain and refill using the included plugs. Instructions are below.
