Help with Rear and front suspension

I have kings installed front and rear, looking at dirt king or camburg for front uppers and I should be fine up front. Also the rear end tends to bottom out I don’t carry anything It’s just over bigger bumps it hits hard. Can I just add a leaf or something inexpensive to help? I’m not trying to spend the most money but I will pay for whatever will help! I’m going to add a front bumper (90 lbs) but that’s about all I wanna do to the truck for suspension

 

If your thinking of a new bumper and already have kings don't cheap out on the rear. Sounds like you need a new leaf pack, skip the add a leaf.

 

How built is the truck currently? How much weight is added in accessories/bumpers in the rear? Stock leaf pack?
