Front & Rear Wheel Bearings for Polaris Sportsman Ranger ACE 400-800

In this review of the Front & Rear Wheel Bearings for Polaris Sportsman, Ranger and ACE models, the bottom line is simple: these are a budget-friendly replacement set intended for owners who want a stiffer, longer-lasting bearing option compared with basic aftermarket pieces. The reviewer found the stainless steel seal cover and thicker bearing material noticeably robust, and they appreciate the inclusion of retaining rings and dual sizes in the kit. This set is best for do-it-yourself riders who need a direct factory-replacement style bearing and value clear fitment guidance.

Key Features

• Stainless steel seal cover: Replaces ordinary rubber seals to provide a more durable barrier against debris and moisture for longer life in harsh conditions.
• Built-in G10Z4 steel ball: Uses a higher-grade internal ball and thicker workmanship to resist deformation under load and reduce free play.
• Dual bearing sizes included: The kit supplies both 40x74x40 and 35x64x37 bearings so front and rear hubs can be serviced with one purchase.
• Includes retaining rings: Comes with the specific retaining rings (7710440 and 7710507) required for secure installation, reducing the need to source extra parts.
• Quality testing: Each bearing reportedly passes a 100% shake and quality inspection, aiming to match original factory fit and function.
• OEM cross references: Lists OEM numbers such as 3515087 and 3515088 so buyers can verify compatibility with their Polaris model.

Who It's For

This bearing set is best for Polaris Sportsman, Ranger and ACE owners who perform their own maintenance and want a heavy duty replacement that more closely resembles OEM construction. It suits riders who experience rear wheel shake or unusual noise and are replacing both front and rear hub bearings in one service session.

Those who should look elsewhere include owners who require an exact guaranteed fit for rare model years without cross-checking the OEM numbers, and buyers who prefer lifetime warranty coverage from a major OEM supplier; some customers reported mixed fit and occasional seal issues, so keep that in mind.

Pros & Cons

Pros

• Stainless steel seal cover provides a sturdier barrier than typical rubber seals.

Cons
