    I'm ordering a 4" suspension lift for my 75 blazer...I'm sure this has been discussed way too many times but I want to make sure that I get the right parts....I'm getting 4 new springs, 4 shocks, ubolts, brake line extensions, steering box brace, and a steering arm. My question is do I need a t-case drop for a 4" kit? Now I just need to identify my axles and gear ratios... I know I've got a 12 bolt rear so I'm guessing a dana 44 front.

    that sounds about right for the parts. Cant help you with the gears. I wouldnt drop the t-case unless you have a rear driveline vibration.

    i my self would flip the rear and pass on the rear springs.

    next get a can of p.b. blaster and sprey the heck out of every nut and bolt. and still plan on haveing a bit of trouble.

    then look here for axle i.d. info. http://coloradok5.com/axleguide.shtml

    Double-check that your rear springs are good before you decide on the flip. I was going to do a flip, then found out I had a cracked spring.

    to get a general idea on ur gear ratio without pulln the cover just jack one tire up and turn it two full rounds and count how many times the pinion turns. i.e it the pinion turns just over 3= 3.08s 3 and 3/4s = 3.73 and so on

    got a locker in the rear just turn the tires once
