Just thought I would add we recently installed the Super Spring to our 07 Dodge dually and it is a great product. Our 3 h 10" sw LQ squatted it just enough that we were flashed thinking our lights were on bright. This perfectly leveled out the load and the stability and cornering is good. It did not affect the empty ride of the truck enough to be an issue. We put it on ourselves. Its very easy. So far it seems to be a great investment. It was about $450 with free shipping. We got it from Tow and Load in Texas. I highly recommend the Super Spring. Just thought anyone considering it might like to hear a first hand review.
