What, are you putting 4d's without cutting? Is there is no need for a 6in lift. 35's can be ran with less than 6in's and that the biggest that's the largest the stock tj axles need to see, but if you have a terdy 35 rear then 35's can make it explode going down the road...kid you not.
what lift are you thinking about running? There is will be so much cost assoiated with that high of a lift that it's crazy.
