    Do you want to keep it with 4" of lift or do you want to lower it back down to stock height??????

    If you lower the rear, what about the front?

    If you have 4" blocks in the rear, I would have guessed that the front had lift springs. Please tell me that there are not blocks on the front??

    yes unfortunately lift blocks on the front. This is a truck that has been parked a while that i acquired fairly cheap. It came with them on there already.

    So i need to get a set of lift springs for the front then ya? then get a flip kit for the rear new u bolts for the rear and might as well go for new shackles and hardware as well. All this to keep my lift and shocks. the bonus would be that the lift would actually flex instead of being rock hard.

    or i could remove lift blocks front and rear get new u bolts and shorter shocks?
    but It has 33 inch tires on it so i would have to trim the wheel wells but they are rusty as hell anyways(I'm in the northeast) so thats not a big deal.



    any opinions on this. Am I overlooking any potential extra cost in either of these options

    thanks again for the good info

    Looks like you have it covered. Don't drive that with blocks on the front. New U-bolts all the way around.

    I can tell you that I am running an 80 K5 with 33's on stock suspension. No fender rub whatsoever. That is with no trimming to the fenders. Clears under most circumstances, but I haven't tried anything really extreme.

    Removing the front blocks is a must. New U-bolts for anything you replace are also needed.

    Here are the options you have:

    1. Remove both blocks, replace the shocks and run stock height. The 33's will probably require fender trimming. I trimmed mine with 33's and a 4 inch lift because of tire rub.

    2. Remove the front blocks and replace the front springs with a 4in - retain current ride height.

    3. Remove both blocks, replace the front springs with a 4in lift, drop in a shackle flip - retain current ride height.

    Depending on the shocks' condition, they may need to be replaced no matter what.

    One thing that gets overlooked is zero rates with the shackle flip. Your rear axle is moved forward slightly because of the rotation on the front hanger with the rear hanger lowered. The zero rates allow for the axle to be moved back to the center of the wheel well.

    Some reading for you on zero rates:

    The link to ORD has the zero rates http://www.offroaddesign.com/catalog/Zero%20Rates.htm

    Good Luck.

    I would only do that mod if it was needed b/c of suspension travel. That seems like a LOT of work to do just to do it.

    What's your build goal with this truck? What type of truck are you looking at having when it's "done" if that day were to ever arrive?
