Yes, I have revolvers on my rig. A few comments/responses...
1) There was never any felt/perceived difference driving with revolvers on-road. They are relatively well designed in this regard... when the suspension is "resting" with the vehicles weight on it, the revolvers "arm" sits tucked into a block of UHMW (or something similar) that keeps it from moving side to side. This makes for quite a stable ride and never caused me any grief on pavement.
2) The ones I have were originally designed for a Jeep Cherokee. Those Jeeps are not especially light-weight... a full bodied K5 with top on it etc would be one thing.... but when I ran them I had no top, no tailgate, no interior etc. The butt end of my rig therefore probably weighed less than a full bodied stock Cherokee.
3) As with most things, Revolvers are a compromise. They do allow a TON of suspension droop, which is always nice. On the flip side they can "unload", or open up when you don't want them too. For me, this has never happened going down hill... but it has when trying to "bump up" and obstacle... instead of the rear end getting up a step-like obstacle, the revolver with just open up about half way when I hit the throttle. Doesn't break anything, just isn't as good as a nice 4-link suspension would be. Of course, the revolvers are a heck of a lot cheaper than a 4 link too.
any other questions, lemme know. My ORD shackle flip and revolver shackles will be for sale soon if anyone is interested lemme know. I want to go with a shackle flip that allows plate-style shackles (DIY or BWP) because it allows more flexibility with respect to changing the suspension, which I tend to do all the time.
