    I have a 88 3/4 ton Suburban with the 6.2 diesel. The lift I am thinking about is all offroad design stuff. Tuff country front springs heavy duty shackles and zero rates to locate the axle 1.5 inches forward. In the rear I plan on a shackle flip and a zero rate.

    My question is will the front clear the firewall and How much fender trimming is necessary? I want to run 38x11x16 Boggers.

    Thanks for your input.

    I have 3" body and addaleafs with mild fender trimming for 39.5s . Its all in the back spacing and the fact that mine doesnt flex that good :D

    I had about 4"s of lift before I started the 52/56 spring swap and I had to cut the back side of the front fender basicly flush with the firewall to clear 38.5x14.50 SX's

    I have 38.5's, Stock 52" fronts (~4-5" lift), 3" body lift and mild fender trimming/bfh to inner fender, and no rub at near full flex.

    Here is some pics of my k5.
    Front suspension: 4" BDS, Ord HD Shackles, Zero Rate with axle moved 1.5" forward

    Rear supspension: 4" Tuff Country with 1 leave removed, Ord Shackle flip, Zero rate axle moved 1.5 back.

    Also a 1" body lift

    Tires are 38.5 Swamper SX's

    Had trim a good bit up front, and haven't trimed the back yet need to get more weight back there first.

    whoa- eery. I'm putting 38.5 11 16's on my K20 with 4" of lift. I plan to pop the 38.5's on with no lift, trim the fenders/inner fenderwell with a plasma cutter, then add the lift later. If you look at it I really think they'll work if you don't have a flexy suspension with no lift and lots of trimming- I plan to trim about 2" up in the rear, and about 2" off the sides up front and 4" above in the front. My tires should be here next week so I'll keep everybody posted the amount of trimming required with no lift.

    My rims are going to be 16x8 with 4" backspacing, so they should syick out about 3/4-1" over stock, which is good

    just curious whether in that configuration the tires have ever hit the fender- ie, was it necessary to lift it 6", or would 4" suffice?

    I've only flexed it for show and measuring as of now but I'm gonna bring the rear down 2" and possibly the front as well in a year. I'll let you know if it rubs at it's current height on October 24th...got a wheeling trip planned. :D

    Thanks for all the info and pics. another ? Are 4.10 gears low enough with the diesel and 38's? I currently have 3.73's and 33's and it does well enough. I also plan on adding a 6.5 turbo this winter.
    Thanks

    that's the same combo I'm going from- and calculated out to keep the same acceleration, you'll need at least 4.29's, but that means 4.56's for good off road measure :D (you divide the tire diameter you want by your current diameter, then multiply that by your current gear ratio (38/33x3.73)

    this is just a heads up to sodfarmer- if you don't already have your tires, order them now. I just got word mine were pushed back ANOTHER three weeks. I switched instead to 38.5-11-15's. I have a feeling that any of Interco's tires that are out of stock now will be pushed back for a good while, being based in Louisiana, so get what you can :doah:

    I'm pretty sure that's where their operations are:

    "Interco Tire Corporation is a Louisiana company that has evolved through three generations into a leader in the development of high performance tires for use on four wheel drive light trucks and all terrain vehicles."
    Interco Tire Corp. PO Box 6 Rayne, LA 70578-0006 Phone: 337-334-3814

    Looks like that is right outside of Lafayette- was that hit hard by the sHurricane as well?


    maybe my boggers being backordered so long is unrelated, but better safe than sorry

    4 inch lift 40's. Most likley more cutting then you want to do, but just showing it can be done.

    I am willing to cut whatever is needed. :D Are those just stock rims? If so do you know the offset? It looks similar to the h2 rims you can find on ebay for ~$250. Anybody know the offset of the h2 rims

    thanks
