At that power level I would stiffen the frame you have the means and the time, You could build it yourself. If you don't have a lot of 'spare time' then the porterbuilt unit looks to be a good piece as is all of their products.

I would stay with the trailing arms if that is what you have.

If your truck is a longbed and has the HD 2 piece driveshaft and carrier bearing, I would stay with that.
