When I ran my buggy on road, I used 50 wt all around and some bald red BK Bars with firm Bomb One's and some old ribs in the front. Blue springs all around, worked very well. Put limiters in the shocks to drop the ride hieght. I think I put 6 limiters in the front and 8 in the rear. So maybe add one more in each for the truck. lock the slipper down. That should be a good staring point.
