This set is really worth the money. In my '06 Silverado 1500, the ride quality is much better than the Bilstien shocks that come with the z71 package. I've ridden it on dirt trails, lots of rocky terrain, and rough terrain, and the thing is hard and soft at the same time. I erase 33 x 12.50 x 18 with some offset. The truck is now more like a truck. The only thing you want to buy are dusters. I would recommend it to anyone using a truck as a truck there.
