That's cool Zippy. I was looking to do that with mine to help keep the rear of the truck a little "tighter" when driving. Mine feels like it leans and wallows a lot.

I ran "Roadmaster Active Suspension" on the back of my truck for most of the summer. (I know, the name sounds pretty lame). It's a tight coil spring that mount between the axle's U-bolts, and the rear leaf spring hanger. It holds the leaf in it's "natural curved state", and is supposed to offer benefits of a rear sway bar, while reducing axle wrap and wheel hop.

It definitely felt like I added a mild swaybar out back. I could corner faster and flatter. Susupension handled "jittery" bumps better.

It raised the rear of the truck up about an inch. I sort of liked the stance, but decided to take them off because I wanted to try to tune the suspension a little more and wanted to go back to stock for a comparison.

I never had wheel-hop issues, so I can't comment on that. If you do a search on here, there was at least one other member running them.
