There are several iterations of these. I have the rubber block type on my truck. They replace the regular 1/2" thick rubber isolation pads on the overload spring perches (where the free hanging overload spring contacts the frame mounted perches) like these (shown in yellow).

As far as how I like them....
Before, when I would hook up my 5er, it would cause just enough squat in the rear springs to get the overloads close to contacting, but not quite. That meant every little bump caused them to contact, and it made a clunking sound. After 500 miles of Canadian frost heaved/cracked asphalt, that gets old. Now, in summer, when I hitch up the 5er, it sets down on the stable loads. Perfect, no more slapping noise/clunking when towing.
Negatives - when unloaded and it's -30* outside the plyable rubber stable loads are now frozen like a hockey puck (Canadian reference :) ), and large bumps (speed humps, etc.) cause a clunking noise when unloaded in cold temps. I am too lazy to R+R every spring & fall, so I put up with that one negative.
Here's another stable load type, this one for GM trucks. I have no experience with these.
