JAVIK Front & Rear Wheel Bearings for Polaris — 40x74x40 heavy-duty stainless-cover kit with retaining rings

JAVIK Front & Rear Wheel Bearings replace worn Polaris Sportsman, Ranger and ACE wheel bearings with a heavy-duty, stainless-steel–covered assembly sized 40x74x40 for improved durability and quieter rolling.

If your Polaris ATV or UTV is showing wheel wobble, grinding noises, or uneven tire wear, these JAVIK wheel bearings are a direct-fit aftermarket replacement designed to match or exceed factory specs. Built with reinforced materials, sealed with a stainless cover instead of a rubber cap, and supplied with retaining rings, this kit aims to restore stable wheel rotation for models across the Sportsman, Ranger and ACE ranges.

Which Polaris models and part numbers do these bearings fit?

These bearings are offered to fit many Polaris models including Sportsman, Ranger and ACE series with compatible hub dimensions. JAVIK lists both OEM and replacement numbers so you can cross-check with your vehicle’s service manual before purchase.

• Common OEM references: 3515087, 3515088, 3585502, 3514635, 3514634
• Replacement references included: 3514917, 3514342, 7710440, 7710507
• Kit contents cover front and rear needs: two 40x74x40 bearings, two 35x64x37 bearings, and matching retaining rings

How are these bearings constructed differently from cheaper options?

JAVIK emphasizes durability by using a stainless-steel seal cover instead of a rubber cap and thicker internal components. The kit also uses a higher-grade steel ball and heavier gauge materials, which together reduce the chance of premature wear under load.

• Stainless-steel cover resists corrosion better than rubber seals
• G10Z4 grade internal steel balls and reinforced bearing races
• Manufacturing includes shake and quality tests before shipment

What exactly comes in the package and what sizes are included?

The kit is packaged to replace both front and rear wheel bearings on compatible Polaris units and includes all retaining rings needed for installation. Having both sizes in one box simplifies a full-axle service so you can swap out worn components without sourcing extra parts.

• Bearing (40x74x40) × 2 — for primary wheel positions
• Bearing (35x64x37) × 2 — for secondary wheel positions
• Retaining ring 7710440 × 2 and 7710507 × 2 included

Will installation reduce noise and steering wobble?

Replacing degraded bearings with properly sized, quality units typically reduces grinding noise, wheel play and uneven tire wear. Performance results depend on hub condition, correct installation, and complementary components like seals and hubs being in good repair.

• Properly fitted bearings minimize radial runout and wheel vibration
• Sealed design helps limit contaminants that cause noise
• Recommended to inspect hubs, seals and bearings together for best results

Who is this for: This JAVIK bearing kit is aimed at Polaris owners, DIY mechanics and shop technicians who need a robust, direct-fit replacement for worn wheel bearings on Sportsman, Ranger or ACE models. It’s especially useful when you want corrosion-resistant seals, a full set of bearings and retaining rings in one purchase, and prefer components that have passed basic quality and shake testing rather than economy-grade parts.
