Rancho 9000 or Bilstein 4600

I've done a lot of changes and modifications to my truck over the last 15 years. Some good, some not so good. By far the biggest mistake I have made is putting Bilstein 4600's on it. They simply do not have enough control for a big camper. It's like driving a boat over big waves going down the highway, the way it sway's and rolls and bounces. Because my arctic fox 1150 has the center of gravity behind the rear axle, the truck pivots on the rear axle with the front bouncing up and down. Just pulling into a parking spot and stopping, the nose of the truck dives about 4 in and then bounces up and down after I stop. Unfortunately I removed a good set of Monroe gas shocks from the front when I put the bilstein's on. If I hadn't cut them out with a torch, they'd be back on there. I'm still going to get rid of the bilstein's when I get around to it. I called Bilstein, they told me that a 4600 is not designed for the load that I am throwing at it. They said that a 5100 is better suited. But a 5100 is not available for my truck. And a Rancho 9000 is not available for the front. If it was, it would be on there. I don't know what I'm going to replace the bilstein's with. Probably another Monroe heavy duty gas shock. Good luck to you.
