    Will I need to lift to run 33x12.50s? I'd assume only a 2-2.5 inch lift? or will they fit stock?

    I have some 2.5 inch addaleaves for the front end of my old dodge. I knew you needed those to run 33s on dodges, but don't know about chevs...

    oh yea, body lifts suck!:grin:

    depending on tire with, spring rate, the answer is... maybe.

    I ran them for a couple years, it would only touch on full flex with the sway bar attached. If you disconnect the sway bar... I dunno. It would most likely touch. You can either trim the fenders a bit, or.. add a small lift.

    a 2" or 2.5" lift should clear those, but I dont know how good "add a leafs" are as a lift system. they might remove a lot of the flexing ability. Thats just my two cents.

    my 33" x 12.5"s hit my front only slightly when going over a bump w/ the wheels turned, so i trimed the inside of my front fenders a TINY bit like 2" max, didnt even have to touch the outter fender, and it was good, now i have a 4" lift and its even better. :)

    6" lift. :) That is what I would go with, I loved the way mine looked with 33x14.50 SSR's and six inches of lift. You could get away with a 2.5" easy. Seems 4" and 33's are a very popular combo.

    I run 33x12.50's on 8" wheels w/ 2 1/2" lift on my burb (2 1/2" front springs, small block in the rear). I have no rubbing issues at all. A 2 1/2" lift is the easiest to do. No new drag link, relocate/re-route the stock brake lines, and no need to relocate the sway bar. I run Tuff-Country EZ rides. I like them, but I'll be swapping over to BDS soon.

    Remember to use all new u-bolts if you do a suspension lift.

    all depends on rim size and back spacing. my first set of 33's were on 8" rims w/ 4.5" backspacing. stock they touch going into driveways fast.w/ 3" liftthey'd scrub w/ the swaybar unlocked. when i got my mud tires(33" tsl's on 15x10" w/ 4.5 BS) they tore my fenders up. the bottom rear portion of the fender was peeled back. u ended up trimming it up to the inner fender and now all is good.

    my 89 blazer sits stock with 33x12.50 yokohama mt's and only rub the inside fenders at full flex with the wheels cut lock to lock, or when i drive off of a curb fast enough to bounce it while cutting the wheels. the wheels are 15x10 stock steel "white spokes" off of a late 70's k5. just put 'em on and if they rub, put on a 2" lift from jc whitney for $300. after all, this has to be the cheapest (and easiest) truck ever to lift.

    im running 33x12.5r15 tsl's with no lift and the sway bar still on. the tires did all the triming that i needed. at full flex they do rub on the wheel wells but i still injoy wheeling it like that.. i would go with a 4 inch lift because u can allways cut the fenders a little to make room for bigger tires. thats the way im going.

    My 89 has a 4" lift and 33-12.5-15's(Dunlop Mud Rovers), on 15x10 wheels.

    I have about 2" or so between the tire and the fender when i turn the wheel.
