    4\" lift

    anyone have a 4" lift and 35"-12.50 BFG muds? or any 35-12.50 muds for that matter. Do you have to cut fenders? Is there a 5" or 5.5" lift kit that has an option of coming with rear springs.

    thanx

    Yep lots of people on this board do. You will have to cut your fenders with this setup. How much depends on the brand of tires, brand of lift, rim width, what type of wheeling you do, which axles you run, hard or soft top, how much crap you carry around, and I think the phases of the moon.
    I used 4" springs all around and added a 1.5" block to the back. Then, I went to the back fender & took a Cresent wrench and kept folding the fender lip back on it's self untill I got back to the support rod. In the front I just cut what looked like the right amount off the back side. For the front side I made a horizontal cut at the mid point of the bumper. It rubbed a little the first time out, but I fixed that with the good ol' BFH.
    I am also going to add 1" longer shackels. This will give me 4.5"F & 5.5"R for lift. If you use one ton axles that will give you another inch of lift. The bottom line is, if you flex it out 35s will rub on a 6" lift if you don't do a little trimming. On the other hand you can fit 38s with a 4" lift if you don't mind doing some serious triming. If you want I can take some close up pics of my trim job.

    Re: 4\" lift

    Not everybody had to cut to put 35 x 12.5 on. I put on my 4" lift and haven't had a problem yet. Of course I haven't flexed my suspension very much yet. After a 2 year rebuild, it won't see a lot a MAJOR 4 wheeling until the novelty wears off. So for right now I don't have problems at all.

    85 Blazer on an 82 chassis, 6.2L Diesel, ORD flip, 35's with no cutting on a 4" lift.

    I ran a 4" lift on a 75 K5 with 35" BFG MTs and twisted the @#$% out of it. Hehe, when I sold it, it dog tracked so bad that on a narrow road I would have the left front tire on the center line and the right rear on the outside line. :) (Yes, a small exaggeration but not much)

    But, I digress, the point is that even with the abuse this Blazer suffered, I had to do some minor trimming on the fenders but no major surgery.
