I've got a 98 12v cc short bed with a KORE pace suspension installed. Truck never did this bouncing until I added a 60 gallon in-bed fuel tank. If the tank is empty, no bounce......only when at least moderatly filled. The bounce feels like it is coming from frame flex........like the mid-section of the truck is flexing. Any ideas on how to stop the bouncing.

Just thought of this.......the bounce reminds me alot of the way a bumper pull trailer can make a truck bounce.

Any advice is greatly appreciated.

Maybe hitting the bump stops? I dont have the same suspension, but I run a 100 gal semi tank in the bed for road trips, and it smooths the ride out. even with the bumper pull trailers I have. Sorry I cant help more

 

Is your tank full? Maybe it needs baffles and your feeling the large amount of fuel sloshing around.

 

have you tried messing with the settings on the rear shocks and adding a little more rebound damping for when youre hauling fuel?

 

The tank is baffled from the factory, and the Kore Pace package does not come with adjustable shocks. I believe it came with Bilstein 5100's that were built to Kore's specifications. Also, I didn't mean to imply that it does the bouncing with a bumper pull hooked up..........I meant to say that the way it bounces reminds me of how some bumper pulls make a truck bounce excessively. I really appreciate all suggestions?

Id speak with the guys that sold you the suspension parts and see if they have any recommendations. You really need adjustable suspension when there is potential for a big difference in payload.
