Key Features

100% Direct OEM Fit
This bottom axis is precision-engineered to match the factory dimensions, length, and mounting specifications of the Surron Ultra Bee. It installs directly into the swingarm and frame with no modification required.

High-Strength Construction
The shaft is made from durable, high-tensile metal, designed to withstand heavy loads, high torque, and repeated impacts. It resists bending, flexing, and deformation under the stresses of off-road riding.

Corrosion-Resistant Finish
The shaft features a protective finish that prevents rust and corrosion, even in wet, muddy, or humid conditions. This extends the life of the component and maintains smooth, consistent swingarm movement.

Precision Machined
Every shaft is precision-machined to tight tolerances, ensuring perfect alignment and smooth swingarm movement. This eliminates binding or play, keeping your bike handling predictably.
