    HELP needed from \'Burban owners

    I am lifting a friends '84 'burban (1/2 ton) and I an wondering about the driveshafts.

    Did you have to lengthen driveshafts with a 6" lift? i know each truck is different, i am just seeing how often it is needed in this case.

    TIA!! /forums/images/graemlins/thumb.gif

    I don't have the 6", just 4", but I'd bet the dshafts need lengthened. I had a truck lifted 6" and if I hit a bump hard enough the rear shaft would slip apart.

    I've got the Rough Country 4" (which is closer to 5") and I didn't do anything with my driveshafts. Both have plenty of length - so I THINK you'll be alright. /forums/images/graemlins/thumb.gif

    i agree with heavy4x4, i lifted mine 6" and didn't have to lenghten my shafts. however i did after i tossed in mine 1 ton gear /forums/images/graemlins/grin.gif... lift it for now and see how things work out, you'll probably be ok unless you get real twisted up /forums/images/graemlins/thumb.gif...

    When we lifted Jason's burb (3/4 ton 14B) 6 inches nothing had to be done with the rear shaft, but he ended up putting a spacer for the front shaft.

    i'm at 5" on the front and i'm running a 1" spacer to help it out, i'm only at 4" rear and that's fine. with a shaft that long you might not have problems.

    What do the spacers look like and where can I get one?

    Hey Zakk
    i say they should be lengthened
    rember the 60 % of length for compression 40% for decompression A.K.A. the 60/40 rule
    here is a cool link i found

    THEY LOOK LIKE THIS
    As far as where to buy one, I think superlift or something like that sells them for about $50, but I could be wrong. Ask Muddysub where he got his - I think he had someone here make it for him though.

    4wpw pn#04310 $65 shipped made by superlift. I have 7'' lift with stock shafts and the spacer gave me more than enough length in the front shaft. The issue with lifting and the front shaft was not so much the length, but the angle and the c/v hitting the crossmember /forums/images/graemlins/frown.gif. A little grinding on the c/v stops and adding the spacer (to move the c/v away from the crossmember) solved my problems /forums/images/graemlins/thumb.gif. I couldn't recommend anything for the rear shaft other than lift it and find out /forums/images/graemlins/tongue.gif I didn't have any problems on my blazer with 5 1/2'' lift and stock rear shaft even after I moved my rear axle back 1 1/2'' /forums/images/graemlins/cool.gif, BTW I did lower my T-case 1''
