Precision Deep Groove Rear Wheel Bearing & Seal Kit

Triple-Bearing Support • Double-Sealed Protection • Built for Ultra Bee

Your rear wheel takes the most punishment — drive torque, hard acceleration, braking load, and every square-edge hit the trail throws at you. When rear bearings start to loosen up, you’ll feel it in drivetrain slop, inconsistent tracking, and unwanted play at the wheel.

The DirtyBike Rear Wheel Bearing & Seal Kit is built specifically to handle those higher loads and constant torque transfer found at the rear of your SurRon Ultra Bee.

This kit includes three precision deep groove ball bearings engineered to manage both radial impact and side loading from aggressive off-road riding. Each bearing features dual rubber seals to help lock out mud, water crossings, sand, and pressure washer spray — the biggest killers of rear hub bearings.

To complete the system, two heavy-duty double-lip seals provide an additional barrier against contamination, helping maintain smooth rotation and long service life in real-world riding conditions.

If your rear wheel feels notchy, gritty, or has side play — it’s time. Replace it with a kit designed for actual off-road use.

• (3) Precision deep groove double rubber sealed rear wheel bearings
