X3. Those three leaves hes runnin dont help. You need more compression in the shocks for the rear steve
. Once the rear is planted, the front is gunna wanna raise more so more rebound up front is gunna be needed. Its a balancing act

Looking at the rear of the truck when launching; the relationship of the axle to the frame/body goes like this. Axle rotates ccw and body rotates cw. The right tire pulls the frame down and the left side pushes the frame up which in turn looses grip on right tire and plants the left tire. The idea is to make the right side act like the left side via traction bar, anti roll bar or air bag assist on right side to help plant both tires. With that being said I dont know how the font end of a 4wd would affect or change this motion. I'm sure someone on hear could explain this better also. I think its anti squat that most drag racers go for, again I'm referencing 2wd cars and trucks.

His bars already induce a pretty good amount of anti-squat but even with a set of cal tracks, you still cant make up for bad shock valving

Sorry. This post wasn't an observation of OP's truck launching. Just how a rear suspensions act in general.

I only run two leaves. His bars allow squat. The stock shocks work fine.

Maybe I'll limit strap the front and qa1 the rear? Hold the front down and keep the rear a little firmer?
