Re: C30 heavy duty rear axle top speed

The GV overdrive unit sounds like it would work well If it is able to get me up to 55 or 60 mph as a top speed. It sounds also like it would probably be the least amount of modification to the truck? Is that correct? Exactly how is this unit installed? Maybe I am misreading something, but from what I can understand from the posts above, it seems like this just bolts on to the truck behind the transmission? Thank you all for all of the responses so far!
