I've had the 7100's for 8 months and I'm not real impressed with the expansion joint ride in my truck. Off road it really kicks ***. I blast down the logging roads in the Sierra's at 50mph and the ride is great! Down the highway, which I the real reason I bought them, not much better. I put 250lbs of tractor weight in the bed of the truck and that made the ride better than anything. I wish I had at least tried the Rancho's first. $2000 on shocks and springs is pretty pricey. But man, if you take it off road, it really kicks ***.
