Dirt Burners! was a Japanese brand of hop-ups for virtually every 1/10 scale off-road buggy of the 1980’s. Many of the products were the same as those sold in the US by Thorp, Parma, CRP, RCH etc. They also sold products from other Japanese manufacturers like Paranoia and Phoenix. Not to be confused with the US Thorp Dirt Burners brand, even if some of the products were the same. The part numbers of Dirt Burners! and Thorp Dirt Burners are different.
