    Quickly....it is simply reversing the shackle to hang below the spring hanger.Several ways of doing it.The advantages are flexier stock springs(less arch than lifted springs),lo cost(free to $180) and you can run longer springs(even more flex).Oh and your ride stays about the same or better.Much better than blocks(axle wrap) and lifted springs(harsher ride).Need more info??Mike

    Thanks Mike.

    The Reverersing Shackles allowed you to run
    longer Springs.

    And runing longer Springs Allowed to have more flex

    By replacing the rear spring mounts,you can place them farther rearward to run longer springs.The lift you obtain is about 3-5".You can buy a shackle mount(thru ORD and others),or you can obtain a rear spring mount from the front of the rear springed Chevy truck,or you can cut out the bottom of your existing hanger.What kind of wheelin' are you planning on doing?Mike....E-mail me and I'd be glad to give you more info.(click on my profile to find my address).

    Adding the longer spring does not lift the truck,it's the shackle reversal that lifts the truck.I'll e-mail you.Mike

    <font color="green"> OK, clarification here - what Bluesman is talking about is actually a shackle flip. The shackle reversal is something that Jeepers do to move the shackles on their front springs to the rear of the spring instead of the front. Doesn't really apply to Chevys, but if you ever say shackle reversal to a Jeeper (Sami's too I think, and some others), then that's what they'll think you are talking about. </font color>

    Ya got one bubba, reel him in /forums/images/icons/grin.gif

    shackle flip-gives you pretty much 4 inches, til you put yer top on, then its 3, lol, and allows for some better flex as the spring shackle can move better front to rear.

    longer springs-odd [censored] we think up to get more flex and it works good. we'd tie a deer to the hood if it helped us flex /forums/images/icons/grin.gif

    <font color="green"> On some 4x4s (I'll use Jeep as the example), the shackles for the springs for the front axle are on the front of the spring, under the bumper, and the spring is just bolted to a hanger on the rear mount. Basically backwards from a GM. There are different schools of thought on how this causes the axle to work when lifted springs are used (stock Jeep springs are flat, so when they compress they go into negative arch, so what I'm about to describe only applies to postive arched lift springs), but essentially what it causes is that when the spring compresses, the axle travels forward instead of backwards, since as the spring elongates it stretches out towards the front. Some people think that this helps force the tires into obstacles and get better traction, but others say that it just causes the ride to get really stiff when the terrain is rough. To some extent, both schools are correct, but the majority of people prefer to have the shackle on the rear of the spring when positively arched springs are used. Not that any of this applies to GMs, but knowledge is always good, I suppose... /forums/images/icons/wink.gif </font color>

    look at a jeep, then look at your blazer. Think of a rock directly in front of the shackle, doesn't really slide on the rock, the rock will push on the shackle and thats not good /forums/images/icons/frown.gif , also when the spring compresses it pushes the shackel forward into stuff also. so if you move the shackle to the rear you don't have that problem.

    <font color="green"> No, that has nothing to do with it. It just affects the shackle dragging on obstacles, and the perfomance issues that I outlined in my previous post. </font color>
