Sometimes went I get on it in 1st gear the back end feels like it bounces. I have it on the top notch on the back to keep it from bottoming out on are bumps.

 

Uhm, did you cut the bump stops? Or replace them with shorter ones?

 

Did you replace the rear bumpstops or cut them?

 

C-notch?

 

the top hole is lowest, the second hole is about a 2/3 drop on a L..
this photo is in the second from the lowest setting..
it also bottomed out on mine that is why i set it here, it also made the back lower than the front, you will have to cut the stock bump stops in half or get shorter ones, and cut or replace the fronts..

this is what my back bumbstops look like..

 

I also had the bottom out problem with the belltech 3/4 kit. Part of the problem is that there is a support crossrail on the botttom of the bed that runs side to side across the bottom of the bed, and it just happensto sit directly above the back edge of the pumpkin. I discovered this when i had the truck over a pit with a guy bouncing the truck from above standing in the bed. You can trim about 2 and 1/2 inches out of the rail above the pumpkin. I also added the QA1's set at 6 in the rear and 7 in front. I don't bottom out any more. I also did the western chasis C notch, but I think the pumpkin/crossrail deal did most of the fix, along with the QA1
