I did the Roadmaster Active Suspension and it works great.

But it stiffens the suspension full-time and lifts the rear as much as 1" at it's full strength. Doesn't bother me, in fact I like the reduced body roll in every day driving.

But wanted even more, so I added these to the front of the over-load leafs. So they have no effect when unloaded, but force the overloads to be stiffer when the trailer is on. And they were cheap. (There's a thread about them somewhere in this forum ...)
