I want to lift my 87 ranger sxt. 6 inches. I know with the stock suspension and ride height I would only get 4 inches of life because this model came stock with a 2 inch higher ride height. Question is will I have to lengthen/shorten/replace my drive shaft after the lift? I know it's standard when doing anything more that 1.5-2 inches most drive shafts have to be lengthened. Thanks for any help.
