So this truck comes with an auto brake limited slip rear differential or something like that right? Is that only when it is in 4wd or even in 2wd? If it is constant is there any way of turning it off, and if you can turn it off is the differential a limited slip? Its alot of run on questions but im curiouse to know the answers. Basically Can you smoke or even spin the tires on this truck? Power braking doesnt sound possible. Someone help me out.
