ok, im not much on suspesion....and i hope this is in the right forum...i have created a gallery with a pic of what im talkin about it looks like it a spacer that sits on top of the axel but underneath the springs..is this just to jack the rear end up on it or what?....any help would be great, and once again, there is a pic of what im talkin about

 

If you're talking about the piece coming from the block under the springs, this is for the "bump stop" so the suspension does't bottom out. Look above it and you'll see the rubber stopper.

 

ahh..gotcha..guess if i would of looked a little closer i would of seen that..lol..thanks
