The Clod Buster and its related models virtually spawned an aftermarket industry of modifications that could be done to it to improve performance and durability.
Many small businesses have popped up over the years to cater to just the Clod Buster owner and a few have since gone on to have great success manufacturing parts for other R/C models.
The Tamiya "Bullhead" which was released November 13, 1990 utilises the same basic chassis design as the Clod Buster, albeit moulded in different coloured plastics.
The most significant difference is that it carries a taller semi-tractor type body, likely inspired by fullsize semi-bodied monster trucks such as "Super Pete".
The only differences between the two are the colors of various parts which were changed from red to blue, the removal of Chevrolet badging and emblems and the addition of the chromed wheels and chassis brace that were previously available only on the Bullhead.
