    I have a 72, I have a set of 35X15.5X15 swamprs. I want to know will a 4 inch lift work, with blocks. I have herd that a 4 inch i wont wave to worry about driveshaft angles. If I go with a 6 inch what am I looking at doing, other thank just the lift. Also what brand should i go with?

    You will need to cut the fenders if you will ever be compressing the suspension. Otherwise, it will "work."

    15.5 is a wide tire. No matter what you do you will have to trim with a tire that wide.

    To run a 6" you would have to...
    Buy extended brake lines (for a 4" you can relocate them)
    Have your driveshafts lenghtened
    Use a raised steering arm (sometimes you can get away without one w/ a 4")
    Buy steps so you can get into the damned thing

  4. When I went to lift my truck I went with a 4 instead of a 6 for the driveshaft reason but ended up having to lengthen my front driveshaft anyway. Wish I would have gone with a 6" lift in the first place. I've got the Rockwell T221 transfer case which probably is why I needed a longer driveshaft whereas the Blazers and later trucks with the NP205 may not need it lengthened. I even had to add a CV Joint to the shaft after it was lengthened. Adding length to a driveshaft is not too expensive. I think mine was like $110, balanced but without the CV joint.

    Thats funny,
    When I done my 4 inch my front drive shaft was perfect but the back one had to be lengthend.
    All they did was put a longer yoke on it. I was a afraid of extreme sag and the thing coming out.
    You will know when you get it in there if its going to be to short.
    And you will have to trim your front fenders I had to with 12.5 wide tires, it could even rub in the back of the fender but you really have to have it smashed on a rock and turned one way or the other.
    Good luck
