DirtyBike Bearing Kit Swingarm Surron Ultra Bee

Precision Deep Groove Double Sealed Swingarm Bearing Kit

Chassis Critical • Double-Sealed Protection • Built for Ultra Bee

Your swingarm pivot is a major load point in the chassis — absorbing suspension movement, acceleration forces, braking load, and lateral stress from hard cornering. When swingarm bearings wear out, you’ll feel rear-end instability, side-to-side play, inconsistent tracking, and vague suspension feedback.

The DirtyBike Swingarm Bearing Kit is engineered specifically for the SurRon Ultra Bee to restore tight pivot movement and structural precision.

This kit includes four high-quality precision deep groove ball bearings designed to handle combined radial and axial loads generated through the suspension linkage and rear wheel forces. Each bearing is double rubber sealed to help block out mud, water intrusion, fine grit, and pressure-washer spray — the primary causes of premature pivot wear in off-road riding.

By maintaining proper alignment at the swingarm pivot, these bearings help preserve rear suspension performance, improve handling consistency, and reduce long-term frame and pivot wear.

Important Installation Note:

Swingarm bearings cannot be pressed straight through the swingarm.

Inner bearings must be removed from the inside.

Outer bearings must be removed from the outside.

For proper removal without damaging the swingarm bore, use our Swingarm Bearing Removal Tool.
