Rear CV Axle & Wheel Bearing Kit for Polaris Ranger 570/900/1000

Our review of the Rear Left/Right CV Axle & Wheel Bearing Kit looks at whether this kit is a practical replacement for owners of Polaris Ranger and compatible models. The bottom line: this kit is for riders who need a heavy-duty, corrosion-resistant axle assembly and maintenance-minimal wheel bearings, and its main selling point is a robust 4340 chromoly axle design combined with ready-sealed bearings that arrive greased and maintenance-free. Installation is straightforward for a competent DIYer and the kit ships with two axles and two rear wheel bearings for full-side replacement.

Key Features

• Material construction: The axles are made with 4340 chromoly steel to deliver higher load capacity and improved vibration damping for heavy-duty use.
• Sealed wheel bearings: Bearings come with a dust cover seal and factory grease, reducing routine maintenance needs and protecting against contamination.
• Corrosion resistance: Designed to operate in corrosive environments including acid, alkali and salt spray, extending service life in harsh conditions.
• High temperature tolerance: Engineered to withstand working temperatures up to 300C, which helps retain strength under sustained heat exposure.
• Fit coverage: Compatible with a range of Polaris models including Ranger 570, 900, 1000 series and select ACE and RZR models across 2013 through 2019.
• Complete kit and support: Ships with 2 axles and 2 rear wheel bearings and offers a two year return window plus technical support for installation issues.

Who It's For

This kit is aimed at Polaris owners who need to replace worn or damaged rear CV axles and bearings across multiple Ranger and ACE/ RZR model years and who value a rugged, chromoly steel axle and sealed bearings that reduce upkeep. It suits fleet operators and off-road hobbyists who expose machines to mud, salt spray or corrosive conditions and need parts built for durability.

It is less suitable for buyers who require OEM-branded components or who need exact factory part numbers for warranty claims. Novice installers without basic mechanical tools may prefer professional installation rather than attempting axle and bearing replacement alone.

Pros & Cons

Pros

• Robust 4340 chromoly steel axles offer improved load capacity and damping for heavy use.
