Title: Leaf Spring recommendations
Post by: bladerunner on March 12, 2012, 02:17:34 PM
Looking at replacing both front and rear leaf springs in my 85 K10 SWB.  I want to leave it at stock height.  She rides real bumpy, even on slightly uneven roads. I do some hauling with her, nothing too big, no overloads.  Not looking at doing anything offroad either, pretty much want to keep stock performance. I don't know anything about springs so whatever you can recommend would be greatly appreciated.

Call up your closest spring shop and order up stock front, and rear packs. Get new U bolts, and bushings for your shackles as well. They will need to know the diameter of the u bolt wire, the height from bottom of the bolt, to the end of the threads, and the ID of them.

     I tried to find out what your spring rate is but dang computer is not willing to help.  Like Blazin said, you best bet for a softer ride is find out what the stock spring rate is and have a local shop make you some that are of a softer rate.  That is if you don't mind spending the money.

Well, I am assuming that my springs are worn out being 27 years old, that is why I was thinking of replacing them.  A buddy said I should leave it as that is how old trucks are meant to ride. My shocks are bad too though, but I figure new shocks will stiffen the ride.

If the ends of your leaves are not worn down and thin, I would recommend taking them apart, cleaning them up with a wire wheel, painting them, putting teflon liners between the leaves and putting them back together with a new center pin.

It will take some time, but it won't cost you much and they will ride a lot better.  Or...www.deaverspringandsuspension.com (http://www.deaverspringandsuspension.com) can do it for you.

To rough, get the seat re-done.  There is a reason for that thick foam pad.  There is also a rational behind the phrase "rides like a truck".  ;D
beyond that,

Thanks guys for the advice. Still new to auto mechanics. I don't really have any friends or family who are real gearheads (or the ones I do know are very invested in family stuff to help out, which is good). So I depend on what advice I can get here.

What did you wind up doing with the springs?
