If your looking for more flex out of the rear check out this guy http://www.alcanspring.com/orbit-eye.htm , and if your looking for more flex out of the front look at these control arms http://www.thurenfabrication.com/controlarms.html I'm still trying to find some place that sells softer springs for the front.

 

trust me our truck do not need any softer springs... it is the shocks that stop us right now, then the control arms which can be modified for better fle... the front is fine with me for right now.. i just need the longer shocks.

s for the rears, i now see what you mean cant really be made to 'flip', but i am going to see if i cant build some, looks easy enough... pretty straight foward. like you said. and the zero block? or what ever,,, i under stand the whole moves the axle, but what makes the zero rate bocks, so special, wouldnt it do the same thing if i was to take my shakles, flip them, take my block out and pt a smaller block in, i could move the axle to where i want it and bolt it up.

 

more on zero rate blocks anyone? read my last and wouldnt that work or is it just good thinnkin

 

To be honest with you, I don't know for sure because I have never installed one personally... just read about tons of people having to use them. It sounds like it would work, but then again I don't know why everyone else would be buying zero rate blocks, or why they would even be produced.

The bolt that goes through the leaf packs protrudes into the block if I remember correctly.

 

If you look at the mounts it has now they are riveted to the frame.
If you cut off the rivets and flip the mounts you can probably do this yourself.
Some clearance holes in the bed might be necessary. Longer shackles, maybe even some Revolver shackles.
Your axle could drop a lot more giving your a lot more articulation.
Maybe one day I'll attempt to do this on my truck.
