?\'s about combining lift with 3/4 ton axles Generally i know that you have to lengthen your drive shafts when you put on a 6 inch lift, but i was wondering if i could get by without lengthing the rear shaft because of the added length of the pinion on a 14 bolt. If so i will also be swapping in a 3/4 ton front axle, so could i get by with just a driveshaft spacer in the front? What is involved in installing a spacer. The blazer is a weekend play vehicle that will be mudding and trail riding lightly, prob less than 5000 miles of driving a year. I would prefer to not have to get a cv driveshaft or longer ones, since i am on a tight budget. I want to put 35's on and winch up front, so i am afraid i will have to trim more than i want with only a 4 inch lift. So will a combination of shims and tranfer case lowering be able to get rid of most of vibs.
