i have them on my '78 chevy heavy half ton. i keep 2 inches between them an top of axel unloaded. you need alot of weight to compress them. they keep the rearend from from bouncing when loaded too. i love em. ive got the rectangle oneswaytogo
I paid $169 shipped to my door off of EBAY. I have them 1/2" from my axle and I loaded the truck last night. it made a huge difference. Im happy with it. It is ten times better than an Add a leaf
