I am looking at 4" lift kits for my YJ. Is there a substancial difference in say....rubicon lift versus rough country? I know the price is higher.....Just curious if in the long run I will be better off spending the extra for the rubicon? Actually the rubicon is 4.5" with about $700 price difference. If the rubicon is gonna make my ride better....I would go for it. Thx again for any info on this matter.
