    I need to get a measurement off a burb, the distance from the tranny/t-case crossmember to the ground. if it matters it's a 1986 with a th400-208.
    I'd measure the Willy's but it's an older frame and has no gear boxes yet,LOL

    I'd be happy to do it for you...but my truck is lifted 4" with 33" tires if that makes any difference to you. Also, lowest point of the crossmember or lowest part of that assembly??? (ie. how close to the ground is the skid plate, etc)

    Lets say the lowest part of the crossmember.
    4" and 33's are fine , thats about where I'll start.

    Okay...just got on my hands and knees in the snow (and more coming down /forums/images/graemlins/thumb.gif) and got 17.5" to the lowest part of the crossmember. (skid plate is about another 1" lower than that). So, figure about 5" on the 4" lift (rough country's are tall) and another 2" for tire radius increase.....and you've got a 10.5" to 11" clearance on a stock 'burb.

    Oh yeah...that's a '90 with 700r4 and np241 if that makes a difference. /forums/images/graemlins/smirk.gif

    PS I need one more measurement and I think Scott(muddy sub) would be the closest, how much room do you have between your tires( from rear edge of front tire to front edge of rear tire)

    Well, mathematically...take the wheelbase of 129.5" and subtract ONE whole tire DIAMETER (two radii).

    With 33's, I get 96.5"....and that is in fact what I got when I just went out and measured. /forums/images/graemlins/thumb.gif
