If you can tighten up the shocks and go up on the air pressure.

Are you running a stick shift???

thank you both i have double adjustable upper and lower control arms, drag springs and lakewood 50/50 shocks. I will try to tighten up the shocks. What tire pres. would you recommend? Also im running a dynamic c-4 trans

I don't think your too far off on air pressure For that tire I'd work in the 16 to 20 PSI range. The higher you can run, the better.

The radial tire likes to be planted hard, but the load needs to be maintained to keep it planted. It's trying to hold, but something isn't keeping it planted. As mentioned above, looking at the shocks would be where I'd start.

Thanks for the question.
