JAVIK Rear Wheel Bearings 40x74x40 for Polaris - Heavy-Duty, Stainless Cover (2-pack)

JAVIK rear wheel bearings (40x74x40) are heavy-duty replacement bearings designed to restore smooth, quiet rear-wheel rotation on compatible Polaris ATVs and UTVs.

These precision-engineered bearings match factory dimensions and include retaining rings so you can swap worn units without altering hub fitment. Made from hardened steel with a stainless-steel cover and an upgraded internal ball set, the assembly aims to reduce play, vibration, and drivetrain noise that develop with age. Each package contains two bearings and two retaining rings, and the part fits a range of Polaris Sportsman, Ranger, RZR and ACE models—check OEM numbers and year/model compatibility before purchase.

Which Polaris models and OEM numbers does this fit?

These bearings are produced to replace several factory part numbers and cover many popular Polaris utility and sport vehicles. Verify fitment by cross-referencing your vehicle’s year and OEM number to avoid returns.

• OEM references: 3585502, 3514635, 3514917, 3515087, 7710440
• Common fitment: selected Sportsman, Ranger, RZR and ACE models—confirm year/model
• Package includes two bearings and two retaining rings for a complete rear-axle refresh

How are these bearings constructed and why does that matter?

JAVIK bearings use hardened steel races with a stainless-steel seal cover and a reinforced internal ball set to withstand heavier loads and resist contamination. The materials and thicker workmanship help deliver consistent rotation under load and extend service intervals compared with basic aftermarket options.

• Hardened steel races for durability under load
• Stainless-steel cover instead of a rubber seal for improved contamination resistance
• G10Z4-grade internal balls and thicker bearing components for longevity

What benefits will I notice after installing JAVIK rear wheel bearings?

Replacing worn rear bearings can eliminate wheel wobble, cut down on abnormal drivetrain noise, and restore smoother handling at speed. Because these are direct-fit units, most owners report a straightforward swap that returns the vehicle to near-factory feel.

• Reduced rear-wheel shake and play for steadier handling
• Lowered noise levels from the hub area
• Direct-fit sizing avoids hub modifications—plug-and-play replacement

What’s included and how easy is installation?

The kit ships with two 40x74x40 bearings plus two retaining rings (7710440), giving you the components needed for both wheels on many rear-axle setups. Installation typically follows OEM service procedures—pressing old bearings out and pressing new ones in—so a shop press or an experienced DIYer’s tools are recommended for a correct, lasting fit.

• Contents: 2 x bearings (40x74x40) and 2 x retaining rings (7710440)
• Installation: press-fit replacement; professional tools recommended

Who is this for: These JAVIK bearings are aimed at owners and technicians who maintain Polaris ATVs and UTVs and need a durable, direct-replacement rear bearing set. If your vehicle shows rear-wheel vibration, hub noise, or excessive play—especially on older or heavily used units—this heavy-duty kit provides a robust, OEM-dimensioned option that balances longevity with straightforward installation.
