Thank you all for the reply's and thank you Carlsson for the forum thread link, that was very helpful! I think RIDE TECH is the way to go and its around a $1000 cheaper than DETROIT SPEED.
One question I do have is before i upgrade all the suspension should i already have the rear end that im going to keep and use for right now I have a original 10 bolt with drum brakes and I want to upgrade to a MOSER 12 inch with disc and i think it will be wiser to do it all at the same time instead of waiting to break my 10 inch then replace.. lol
