Tamiya 54332 F104 R Shaft Counterweight OP-1332 Balance Upgrade  [54332]

Tamiya 54332 R Shaft Counterweight Overview

The Tamiya 54332 R Shaft Counterweight is a straightforward upgrade for hobbyists wanting to dial in their F104 chassis. Once fitted only to the F104X1, this part is now supplied across the F104 family to help correct balance without adding unnecessary rotating mass.

Left-side Balance and Rear Grip

Made to mount on the left side of the F104 chassis, the counterweight helps even out left-to-right weight distribution, which is useful when differential components sit on the gear case right side. At 19.7g and fitted with ball bearings, it reduces stress on the axle shaft while aiding rear wheel traction.

Fitment With F104 Variants

This counterweight fits multiple F104 chassis types, covering the F104, F104PRO, F104W and F104X1. It is a simple path to improved stability for track setups that need a small balance correction.
