    Shackle Flip and Front 4\" springs

    I am planing to go with a 4" lift. Shackle flip in rear and 4" springs up front. I was just wondering what are the most common things that need to be done to the driveshafts with a 4" lift. I will eventually go with a cv shaft but I currently don't have the dollars to do it.
    Thanks for the help!

    With a 4" you should be able to use your stock shafts. I'd definitely check the engagement, but you should be fine. Depending on your gears and tires, you may be able to get away without a CV for a while. Lower numeric gears with larger tires keep the driveshaft speed down to help with vibration.
    You should plan on dropping the t-case an inch or so, and then invest in an angle finder to measure and match up the angles. With the flip and a non-cv shaft, you'll most likely need to shim the pinion down a little. Probably 2-3 degrees, just as a guess.

    Best way to go is save up for the CV asap, it makes life lots easier in these.

    I've seen teflon pads as far back as '82, so it might be from '81 up.
