84305 TRF502X Battery Holder Weight (Side/Center)
These ballast weights have the same shape as the battery trays of the TRF502X chassis and can be attached under the trays, thereby saving space. By attaching these weights, the center of gravity will shift towards the rear and help you adjust your machine's balance to match the track layout.
