    Ok i know there are a lot of different factors to this( condition of parts etc.) But how much susp. lift can i get on a k5 before i start getting into driveline problems? I want to go as high as i can without breaking u joints everyother day. At this point i dont really want to get into the cutting of the rearends to reangle the hog-heads and all that , as this is a daily driver for me. I would really like to do 8" susp., and 3" body with 40's but i dont want drive line probs. Any and all input will be appreciated. /forums/images/graemlins/k5.gif

    You should be safe with a 2-3" of suspension lift and no driveline problems. Anything more than this and you are most likely going to have to make changes to the drivetrain.

    With 8" of susp lift you can expect to do MAJOR modifications to the drivetrain to eliminate vibrations and correct for steering. You will also need extended brakelines.

    With 40's, heck you might start looking at rockwells, keep your ujoint angles the same.

    all it takes is money to cut n turn a dif and angles can be fair for 10-12" springs.
