The new Shorty Battery Foam Set from the guys at Avid perfect compliments racers running the lightweight shorty packs in their B4.2 buggies and T4.2 trucks.
The set includes two large, screen printed foam blocks with perforated cut lines which allow for a mid and offset battery location in either a B4.2 or T4.2, whilst also fitting older versions like the B4, B4.1, T4, T4.1 models.
