RE: Official Muggy thread
Dunno'.. But the Muggy is very sensitive as far as gearing goes.. Basically, the chassis flexes too much, causing clutches to fry. I ended up getting this alu rail to drill into the chassis left of the tank, and it stiffened it up a bit, and helped.. With bigger tires though IMO you are asking for issues.. Stock Muggy tires are already way too big and heavy..
