I just did a SFA on my s10 blazer and the springs I used arent holdin the front up were I want it, I dropped it off at a spring shop owned by a dude I went to school with, he is thinkin re arch them, is that a good idea, wont that make em stiff, and not flexy? I just wanted some one with experience with this to give some insight

I'm interested in this too, as i need to get my ass end up a few inches.

If you re-arch them, they'll eventually just sag back to wherever they were. I'd replace 'em.

Hey, as if you needed another reason not to re-arch them: re-arching makes the distance between the spring eyes closer together. This can make the lower end of the spring shackle lean inward (toward the center of the spring instead of away from it, like it should be). When the shackle bottom leans inward, this makes it so the force of the bump has to lift the truck before it can extend out and results in an ultra harsh ride and terrible handling. Aftermarket springs start out slightly longer to begin with to prevent this.

I wouldn't have thought it'd be so tough to find an aftermarket spring... Have you considered measuring the spring and looking for one at the local Pick & Pull from a different application? (i.e. Jeep, Ford, IH, Chevy fullsize...) I mean, a leaf spring is a leaf spring-- just so long as it fits your application...

This would be my recommendation also. Other than re-arching (which I wouldn't do) that and going to National Spring and forking out $$$$

Time to get out the yellow pages. Any spring place worth anything should be able to fix you up pretty inexpensively.
As already been said "rearching is just a band-aid".
There is a spring guy near here that will put a new leaf in and then rearch a set of springs for under $100. This way the new leaf will hold the arch for a much longer time.

I don't think that these re-arched springs are going to be much if any stiffer than there were before being re-arched. There will sag but so will any other new spring that you use. I suspect that these re-arched springs will sag a little quickley which is why I would steer clear of re-arched springs (just my two cents). What I would do is to either have springs made by a company like Alcan or National, or I would just convert to a different type of springs for a more common 4x4 vehicle. :)

I used rear leafs off of a late 70's camaro, and off of an 85 cherokee, the camaro main leaf is perfect as far as length and centering my axle on the blazer, but it is made to be damn near flat before it starts to catch the weight of my truck, I have a pack of seven leafson each side, and I am gettin some mad droop outta them, cause they are so soft, I am just goin to let him do his thing, and see what happens. I dont really have the funds after all my other mods to get a set made yet, (I have heard some fairly high prices)

I'm going to assume that the people that don't like the idea of re-arched springs, have never personally had them, but if they are done correctly they are a good and reasonable alternitive to new springs. I've seen brand new "After Market" springs sag bad after a year, and re-arched springs last many years.

I was going to start a new thread but I figured I would dig this one up out of the archives:flipoff2:

While searching for "rearching springs" I found this thread and wondered if anyone knows how spring shops rearch springs?
A friend of mine gave me a set of allpro 4" front springs that are sagging (maybe 3" now) . What I want to do is put the life back in these springs and use them on my toy(try to get 4.5" out of them). I have access to a 50 ton break press that can be controled to bend .001" at a time. Is this how the spring shops do it? if so I will save some $$ and do it myself. I have also read where people say a rearched spring won't last:( Why not? If after you rearch the spring set bump stops correctly and I would think that you shouldn't have a problem. Have you people that done this had any problems with you truck sitting level from side to side?
