great looking project!!! You obovisouly know all the pros and cons of using the products you have chosen!!!! Nice1!
regards to finding an ideal suspension.... have you considered the baja front shocks for a savage... they are quite stiff and not good on a normal savy, but with the extra weight you are putting on the truck, these may be one you need??? LST Shocks are big but with weak shock shafts, whats the point... These are like BP Bigbore shocks!!!! I was going to put these on my truck, but they are quite heavy shocks....
Also good luck with the Lower A arm decision.. I have always wanted to extend the arms but never found a suitable drive shaft alternative that offered the strength of the stock SHD Dog bones. So i stayed away... Keep us posted on how this develops!
Gd Luck!
MMMHVXL FTW!!!! when is it getting here!!! ARGHH!!!
