The chassis on my truggy is the Extreme racing chassis mentioned above. I also have other chassis from Penguin and BMI that I'm thinking of doing a buggy or another truggy. That truggy I bought on Ebay. The guy did a great job and the towers were probably made by him. I designed a chassis for a 1/8 scale truggy and I sent the drawings to a very talented guy to see what he thinks.
