because the traxxas extended chassis isnt welded, is already cut out for the new center diff with rear brakes, and has all the holes drilled out and ready to go. Its just a matter of dropping everything on and screwing it down. With any other chassis your gonna have to modify it to fit the center diff. Plus the traxxas chassis is only 60 bucks so why not.
