for mud racing you stagger either the gears and/or tire sizes. the idea is for the rear to push the truck, but with the front turning faster, you can get the truck to steer as it will try and pull the truck. Without seeing a detailed breakdown of whet is in this truck, you can't say what it's worth. to you, maybe nothing. but to somebody else, alot. There is alot of time put into these trucks, you like to think you can get some of that back when you sell them. I think the truck kicks ass! but I wouldn't want it!
