Polaris Differential Hub Assembly
About this part
When the bushings on your OEM diff hub go bad, it can take the whole hub assembly with it, leading to leaking oil, sloppy axles, and increased steering effort. Instead of living with bad handling and a fused hub, replace it with SuperATV’s Polaris Differential Hub Assembly. It’s a full diff hub replacement with upgraded components that outperform stock. Plus, it costs a fraction of an OEM hub and ships fast.
Increased Quality, Decreased Cost
Think we can’t make a cheaper Polaris differential hub assembly that works better? Think again. OEM hubs use steel bushings that can cause the hubs to fuse together. Our high-quality steel hubs use a sintered bronze bushing to greatly reduce wear for better engagement and disengagement even after years of riding.
Frequently Asked Questions (FAQ)
The differential hub assembly supports the axle output where it exits the differential and keeps everything aligned and sealed. When it wears out, you can get oil leaks, sloppy axles, and increased steering resistance.
Common signs include diff oil leaking around the axle, excessive play in the axle, grinding noises, or heavier steering effort. These issues usually point to worn or seized bushings inside the hub.
This hub assembly fits a wide range of Polaris models, including RZR XP 1000, RZR Trail and S models, Polaris General, and Ranger XP 1000 models. Fitment is determined by your OEM differential and hub part numbers, so matching those is essential.
OEM Polaris hubs use steel bushings that can gall and fuse over time. We use a sintered bronze bushing that greatly reduces friction and wear for smoother engagement and longer service life.
This is a complete differential hub assembly, not individual components. It replaces the entire hub with updated materials for improved durability and performance.
Yes, the hub assembly is designed to work with both OEM Polaris differentials and SuperATV complete differentials. That makes it an easy upgrade or replacement regardless of your diff setup.
Installation is the same process as replacing an OEM hub and can be done with standard hand tools by an experienced DIY installer. We provide clear installation instructions to guide you through each step.
Replacing the hub is faster and more reliable than rebuilding worn OEM bushings that may already be fused or damaged. This assembly costs less than OEM while providing improved durability and long-term reliability.
