KO Propo 35033 Aluminum Upper Case - BSx2/3 Servo Upgrade  [KO-35033]

Upgrading Servo Durability with KO Propo 35033 Aluminum Upper Case

The KO Propo 35033 Aluminum Upper Case is built to fit the BSx2/3 servo family and adds a clear durability improvement. Machined from quality aluminum, this top cover strengthens the servo housing to resist impacts and keep internal parts secure during aggressive driving or racing.

Why Aluminium Works Well for Servo Tops

Aluminium provides an excellent strength to weight balance, offering protection without excessive mass. Replacing the stock upper case with this aluminium version increases resistance to knocks and improves heat transfer, which helps the servo run consistently in prolonged or demanding sessions.

Designed for a Precise BSx2/3 Fit

This upper case is shaped to align with KO Propo BSx2/3 components so mounting holes and key surfaces match accurately. That makes installation straightforward and preserves servo functionality whether you are refreshing worn parts or upgrading for tougher use.
