    OK guys, I know some of you have done this, by opening the spring clamps, do you get more axle wrap under acceleration? Does anyone know how much more flex you might get by doing this, is it even worth it for just a little more flex.

    I opened up my front clamps to almost totally open and the rear springs i took the bolt out completely.

    In the rear I got a lot more flex, but it really flexes the main leaf and Sometimes I am suprized it doesn't crack.
    On the front it works really well also.

    Not sure how much I gained by this, I haven't been able to get on the forklift in a while.

    I would like to get some 9012's soon and then test it.

    Steve,

    I did this on mine and gained a couple more inches. I didn't notice any difference in axle wrap. I just recently closed the clamps on the front, because I was tapping out the front brake lines. A little to much droop.

    I have the Procomp. I am going to put limiting straps on front, because the shocks are not stopping the droop. It is drooping more than I expected.

    I read in a mag recentlly that it is a good way to break your springs. I don't know from experiance, but that's what I read. I'll try to find the artical tonight at the jobby-job. I'm going to stay awake just for you!!!

    I jusr read the same thing last night. Said that it lets the springs flex too much in one direction and then flex too much in the opposite direction thus making the springs week at the center point of the bend. Sorta like bending a coat hanger back and forth till it breaks.

    Don't you buy no ugly truck!

    Steve, I'm sorry it took me so long to look this up. I read in Dec.2000 4-wheel & off road, pg. 38 under Springs, why not to remove or loosen the spring clamp.

    Well, the day I bought my Jimmy I noticed that 2 springs were broken in the rear end, the rear really sagged. So I replaced the broken leaves (1 on the drivers side and 2 on the pass side), and it still sat low in the back. I removed the u bolts again and installed 2 extra leaves in each side. Now it sits a touch high in the back (unloaded). Perfect. The point is that I had to remove the clamps to get the new leaves in, and Ive ran them open ever since. When I look at the rear end under accelleration, it wraps a bit, but I dont think having the clamps would stop it at all. I have never broken a rear leaf, but it sure droops down when I use the Hilift to raise the truck! The springs dont flex downward tho due to the extra leaves so I dont know how the negative flex affects them.

    According to the artical , it's the fexing from possitive to negitive arch over and over again. It's not not just dropping, it's both dropping and compressing. I don't know from experiance, just from what I've read.
