Anyone try the Hellwig Pro Series?
Looks like a clean progressive design that they took the rattles out of.
In the past on those products I recall you had to crank down the end U-bolts to get away from the rattles but that made for a stiff unloaded ride.
So far I have tried Air Bags and the AirCell's but still not happy.
