Zinger Front & Rear Wheel Bearing Kit for Polaris RZR/Ranger 800 — 4-Piece Set, OEM-Fit Durable Seals

Zinger front and rear wheel bearing kit is a direct-replacement bearing set engineered to restore smooth, quiet wheel rotation on compatible Polaris Ranger and RZR 800/570 models.

This kit contains two front and two rear wheel bearings designed to replace specific Polaris OEM bearings and match factory fit and function. Each bearing set meets dimensions and tolerances used on a wide range of Ranger and RZR vehicles from model years 2010 through 2015, providing an economical alternative to OEM parts while maintaining reliable performance for on- and off-road riding.

What exactly does this bearing kit replace?

These Zinger bearings are dimension-matched to common Polaris front and rear hub bearings so they fit into original wheel hubs without modification. They’re intended as direct replacements, not OEM-branded parts, and correspond to the listed Polaris part numbers for front and rear use.

• Front bearing dimensions: 44 x 72 x 33 mm — replaces Polaris front OEM numbers such as 3514699, 3514627, 3514924, 3514822, 3515090.
• Rear bearing dimensions: 40 x 74 x 40 mm — replaces Polaris rear OEM numbers like 3514635 and 3585502.
• Sold as a 4-piece set: 2 front + 2 rear bearings, ready for a single-axle replacement job.

Which Polaris models and years will these bearings fit?

The kit covers many Ranger and RZR variants but is not universal for every Polaris vehicle. Carefully review fitment to confirm compatibility with your model and year before ordering.

• RZR S 800 and RZR 800: model years 2010–2014.
• RZR 4 800 and Ranger 4x4 800 EFI (including CREW): 2010–2015 for most configurations.
• Ranger RZR 570 EFI: 2012–2015; Ranger XP 800: 2012; Ranger 900 XP: 2013–2015; Ranger 4x4 900 Diesel and Diesel CREW: 2011–2015. Not compatible with all RZR 900 variants — only Ranger 900 models listed.

How do these bearings perform compared with OEM parts?

Zinger bearings are manufactured to meet OEM-style dimensions and heat-treatment specifications so they seat and run like the factory units. They’re intended as quality direct replacements for routine maintenance or repair when original Polaris bearings show wear.

• Precision-turned races and hardened steel rollers for long service life under trail loads.
• Sealing designed to resist dirt and moisture typical of off-road use, extending bearing life.
• Sold as non-genuine replacement parts that meet OEM fit and clearance standards.

What comes in the package and what should I know before installing?

The kit ships with two front and two rear bearings plus standard packaging for parts protection. Installation requires proper hub removal and bearing press tools; reuse of seals or spacers depends on your hub condition.

• Package includes: 2 front wheel bearings and 2 rear wheel bearings (four bearings total).
• Recommended: professional install or a press tool to avoid race or seal damage.
• Inspect axle seals, hub surfaces, and spacers during replacement; replace seals if worn to protect new bearings.

Who is this for? This bearing set is aimed at owners and mechanics of compatible Polaris Ranger and RZR models who need a reliable, cost-effective replacement for worn wheel bearings. It’s ideal for routine restoration during wheel service, DIY riders with a press or shops performing hub rebuilds that require exact-size, OEM-fit bearings without paying OEM pricing.
