Troubleshooting Bounce in Truck with Camper in Bed  

Judy V- One thing you need to keep in mind in poor road conditions you are always going to get jounce. The stiffer you make everything in the back, the harder it will rebound and push the rear of the truck up, causing the weight to transfer to the front and then again back onto the rear. This will repeat until the suspension settles. Suspension is design compress and rebound in range. How old are the original springs in the truck? You certainly can have tired springs even with a 3500. Start here, additions are aiding but if the main springs are weak the other components are like a band aid. If the springs are weak, you could replace at a local spring shop, and they can add additional leaf's to compensate for the load. Remember springs hold weight up, shocks help control the up and down speed of the spring movement. Dialing in the suspension will never be perfect, again if you are good most of the time and certain sections of the road are tough, that is part of the game. I am a fan of air bags and have use successfully, I use the stable load currently on a 15 F350 DRW. They allow the lower helper spring (overload to engage sooner.) I have had 5500 lbs in the bed, will still squat with that weight, drives great, when you hit bad parts of the highway the truck will still bounce with the dips. I pull a camper also 35'- will tow level and drive like a dream, until some parts of the highway are unbearable. I keep repeating road condition, because it is important. How does the truck drive unloaded, are there certain area you can test unload verse loaded you will see the truck react in a similar way, but obviously more violent loaded as there is more weight transfer taking place. Before buying every bolt on, check the original springs, check the truck uploaded. You could also look at installing timbren on the front axle to reduce the front to rear movement. A lot of people only focus on the back. Hope this helps a bit.

I put these on my 2006 Chevy Duramax and leave them engaged all of the time since most of my use is pulling a 20 ' flat bed trailer or a 7x 14 dump trailer. They engage the overloads springs much quicker and keep the pickup much more level. I hauled a 9000 pound log on the flatbed and the pickup set almost level and it handles much better. Granted, the ride is a little stiffer when unloaded, and you can feel the rough roads a little more, but I think they are a good solution for stabilizing the vehicle.
