The Bruiser chassis is an evolution from the 3-speed chassis. There are a lot of minor changes, but the most visilble ones are the motor, radio box and battery position. Also wheels are different. Like the 3-speed chassis, the Bruiser has leaf springs on all four corners, but they are softer and this time dampers are included. The ride of the Bruiser is much smoother and realistic, if you like, than the Hilux and Blazer. The gearbox is similar, featuring three selectable gears while driving. The Bruiser was re-released in 2012 with a lot of smaller changes to the chassis.
