Any help/ideas of bouncing puller??

[mudmizer]

I have been trying to get the bounce out of my puller and have had a some success, but anyone have any help/ideas.
Rear is locked solid for the pulls. Rear axle has ladder bars. Hitch runs solid to the frame just under cab rear. Front springs are clamped to reduce spring wrap with torqe arms to the center of the frame. Running 35 inch BFSs with 60 psi. Truck runs in 4500-5500lb class and I weigh 5480lbs. I am not allowed to hang any weight on the front even if I droped weight somewhere. I have gotten a few 1st, but more broken parts than places. The biggest problem is it's short wheelbase. Due to the hop I have to get on and off the gas and I loose momentum. I'm thinking of a shorter tire for less side wall. 33s?? have 4:56 gears.
