A rumble or vibration on an otherwise smooth trail usually means the carrier bearing on your Polaris RZR XP Turbo is worn out. This Heavy-Duty Carrier Bearing replaces OEM part 3515040 with a self-aligning, greasable, fully sealed bearing in a two-piece housing that's easy to install. Rubber feet and washers limit vibration, and a locking collar keeps the bearing from walking off the shaft. Choose 6061 billet aluminum or A380 cast aluminum, then decide whether to add a remote grease line for no-disassembly maintenance. It fits the 2016-2021 XP Turbo and XP 4 Turbo.
Highlights
- Durable, self-aligning bearing
- Greasable and fully sealed for durability in any conditions
- Two-piece design for easy installation
- Rubber feet and washers limit vibration
- Locking collar prevents slippage
- 6061 billet or A380 cast aluminum
- Optional remote grease line
Self-Aligning Bearing
The self-aligning bearing reduces side load from the prop shaft, which is key to keeping vibration down and extending bearing life. The sealed design keeps out the water and grit that kill stock bearings.
Locking Collar
The included collar clamps evenly around the shaft for a strong hold. It keeps the bearing from walking and prevents wobble and vibration from developing.
Two-Piece Design
Instead of pressing on a single bearing, the two-piece housing is positioned and secured in minutes, which makes both installation and later maintenance easier.
Billet or Cast?
The 6061 billet housing is the strongest choice for riders who push their RZR to the limit. The A380 cast option is more budget-friendly but still stronger and more reliable than the OEM bearing.
Remote Grease Line
The carrier bearing sits in an awkward spot under the machine. A remote grease line lets you grease it with no disassembly, so regular maintenance actually happens. If you ride in water, mud or dust often, it's worth adding, because fresh grease pushes out contamination and extends the bearing's life.
What's in the Box

Who It's For and What Pairs Well
