I want to upgrade the rear end
Hey all,
I am looking to upgrade the rear end in my transam. Currently its the stock 7.5" 10 bolt rear with a 2.73 one tire fire open diff. I was thinking of upgrading to a more heavy duty rear end that can actually take some form of power transfer without snaping axles every other launch. I figured that most of you out there have done a swap in this area so I figured I would ask you where you ordered the parts or the whole rear end ready to rock. If I can order a full rear end that is just a bolt in and go setup then that would be the best bet. Any websites would be greatly apreciated.

I was searching on thunder racing and I found this items here. What do you think of this 12 bolt rear end. will this be a direct bolt in and a simple install?
