SON-A-BICH Take a look at the rear end!

Why would you want to change gears? Once you have the combo down you shouldn't need to. Even with the auto in my car I've broken another 3 sets of gears, but at least two of them were my fault, with a four speed it's going to be super easy to screw up and then, well buy buy. :lol:

I got the aluminum carrier from MP for my 8 3/4 and it probably helps absorb some of the shock but still with that kind of torque and a four speed it's a lost cause. The shock loads are just to much for it.
