I had the same issue. The right frt wheel picks up under extreme acceleration. Torque twist. The frame flexing is some of it. I did notice the lower I got with the truck, lashing the A Arms to level, the less it did it. Had 3 T-Maxxes and 3 E-Maxxes. They all did this to some level.

Try this, remove one of the left frt shock spacers, a 1/4 inch one. This lets the left front suspension absorb some of this, before allowing the right frt to rise.
