    What is the biggest tire I could fit on a blazer with a 4" lift?
    OR even 4" with fender cut outs?

    You can fit 35s with 4" lift, but they will rub with a soft lift. If you go rough country lift they will not rub, because it will pick a tire off the ground before if flexs. If you do cutouts you could get away with 36s on a soft lift or even 37s.

    4" steering arm, longer brake lines, and probably have to lower the t-case 1". Lowering the t-case is easy, ust use the spacers that are on top of the crossmember and put them between the crossmember and the frame. As for the steering arm is like $65.

    Gotta disagree with you on the Rough Country DD. I have the Rough Country 4" all spring lift on mine with 33's and they will flex and the tires will rub.

    How big of a tire depends on what your wheeling needs are and how much you're willing to trim. Generally 4" and 33's but if you do cutouts you could get away with 36s maybe even 37s if you leave the sway bar hooked up.

    Well in that case i might as well stick with the 6" lift, if i have do the same modification with a 4".. Is there a 6" lift kit out there that comes with alot of the extra steering components needed to complete the lift with out buying everything seperatly?

    How much you wanna cut out? Mine works good with the 39.5s on a 3" lift. Better buy a few extra sawzall blades, though.

    It must be an old setup becuase my buddy put a 4" lift rough country on his and the front doesnt move at all. The rear is blocks so it flexs. When we lift the front of his truck on the rack at work they dont come out at all. Rough country front spring rate is 604 lbs/in versus tuff countrys is 295 lbs/in.

    i disagree as well, my RC 4" was 2 months old and i could rub 35's, and i even had a 3" bodylift!! plus, the bottoms of the fenders were already pushed up a little from previous rubs before the lift and 33's.
    matter of fact, with major trimming, i still managed to hit the INNER fender where it was cut near the bolts. of course the other tire was way of the ground, so the full weight has on that side. i had 38.5's on too. thats still a long way to reach though.

    My old Rancho 4" fronts are supposed to be over 500 lbs/inch, and I stuffed my 35's into the fender a few times till I trimmed it. Rim offset has a lot of effect on whether or not the tires will hit the fender too.

    Well I am just going from what ive seen. I knoy my truck rubbed like crazy down a trail, and my buddies didnt. We took the same line. I have the tuff country ez ride 4" lift with 35s on 9" wide wheels and 3 and 3/4" backspacing. My buddy has the rough country 4" lift with 35s on 12" wide wheels and 3 and 3/4" backspacing. Mybe they flex with alot of weight on them where as flex on the littlest thing. I just took my Jimmy out for the first time lastnight since the rollover, and I have new fenders on it, it rubbed going down a washboard road.

    Actually, I bought the lift about 2 months ago and it has only been on the truck about 1 month. I haven't even put 1000 miles on it yet since the lift. I'm running 33's on the stock 15x8 rallys. The pic in my sig was taken at Potosi a couple weekends ago. The lift was on the truck less than 2 weeks and only street driven about 500 miles before the pic. Installed on the truck I netted just under 7" of lift. They're beginning to settle a bit now but not much (less than 3/4"). And it still rides very good, even better than it did stock.

    DD, did your buddy reuse the old bushings or something. Or perharps he tightened the spring bolts with an impact. Something seems fishy about this truck. I got 35s and a 4" RC lift and I have the front and rear outer fenders trimmed just above the inner fenders and then beat the inners up to be even and I still rubbed my front at the same place Scooter did. RC flexes just as good as the rest IMHO.

    I dont know for sure. He has had the lit on for about a year now, and he had his uncle do it for him so he doesnt know either. All I know is it sucks to dive and its way too stiff.
