    My truck sags quite a bit in the rear. Imagine that. I talked to a guy locally, and he said bring the truck down, tell him how I want it to sit, and for $275, he will re-arch the springs, add a leaf, all to my height specs.

    My problem is that it is kind of hard to tell exactly how high the rear should sit to be level with the front. Does anyone know if the wheel well openings front and rear SHOULD be the same height to the ground if the truck sits level? I was thinking of just jacking up the rear of the truck until it looked level, then measure the wheel well opening to ground height, but thats almost like guessing.

    I'm thinking that when I have him do it, have the truck half full of gas, otherwise, the truck would end up jacked up in the rear end when close to empty, or sagging excessively when I filled it up. Any thoughts, ideas, specs?

    You can get new springs cheaper than that... Just ann a add-a-leaf... 2 incher will do nicely...

    Um... yes officer I know it's too big...

    The amount of gas shouldn't make that much of a difference ... unless your suspension is that shot (which it shouldn't be after everyhting is all said and done). I think jacking up the rear axle until it looks right is a great idea ... look at the ride height string ... jack it up from the frame and measure from the rear axle to the frame ... you'll end up with something that you like ... my 87 silverado, that I think is stock (except for 32" tires instead of 31"), sits a little nose low ... I think it look's mean and angry (good for a big ass truck)

    FWIW

    Two things I do know;
    1) Re-arched springs will lose there arch quicker than new springs.
    2) The wheelwell openings are different heights. However the body line above the fenderwells on the 81 and newer trucks is a good indicator of level.

    Have you thought about the '0' spring rate 1" add-a-leafs from ORD? I guarantee those won't sag again in a year.

    Gonna head over to that forum and ask the same question...I'd really rather replace all the leaves, I have heard the add a leaves are a pain in the a$$ to put on.

    Add-a-leaves aren't too hard to install. You don't even have to remove the spring packs from the truck.

    Once you have the axle unbolted, just C-clamp the springs to keep them contained, then remove the center pin.

    Loosen the clamp to slowly release the energy in the springs.

    Slip the new leaf in place and install a new center pin.

    Clamp the spring pack together with the C-clamp and tighten the center pin and cut it to length.

    Bolt the axles back to the springs.

    I did both sides on my S-10 in a couple of hours.

    Not "add-a-leafs", he's talking about "zero-rate" leafs. I wouldn't use the AALs but the ZRL are fine. Check them out at ORD.

    Hey Dorian... You might just want to consider a 2.5 inch lift kit w/ front and rear springs.. my truck sits nice and level now .. no sagging.. I installed Rough Country's lift kit.. and the 2.5 inch kit doesn't cost that much.. and talk about a nice ride...

    That's interesting, I thought he had them on the site now. Oh well, rusty got you the link at CK5. What I think of as "add-a-leafs" are the high arch things that preload you spring pack to give you lift and make it ride like crapt. These "zero-rate" leafs are really just spacers bolted into the spring pack just like another leaf. They don't have the drawbacks of blocks or add-a-leafs and are perfect for fine tuning your lift.

    I got my add-a-leaf from 4 wheel parts wholesalers about 4 or 5 years ago. My rear end sits just a little higher than the front which I think looks good. They haven't sagged at all and my ride isn't much different than stock. They weren't that expensive either.

    How much does it sag in the rear. Jack it up and measure how much higher you would want it and buy a small lift block from AutoZone, Pep Boys, etc and stick it down there. A samll one won't really affect axle hop like a big one would, and it should only cost about 10-15 bucks

    i have 4" super lift springs all around and a 2" block in the rear and if you measure to the body line its close to level. u can see mine in readers rides. its the blue ox. i think the photo i have there now would be hard to see the levelness (is that a word?) if you want to see it ill e-mail u a photo. just give me the word.

    about the rearc mine died around a year and it looked goofy as hell cuz it sagged all sorts of different ways. and it cornerd like crap. i sure love the new springs.
