My friend has an 01 dodge probably around 400hp that we cannot get to stop bouncing. the truck is 6 speed, 3.55 gears, fairly new 285 bfg a/t's, pulls in 4lo 4th, everything tried so far does not get rid of the bouncing. In our 7500lb class he can have trac bars and stops and make weight. first stops we built had about 1" travel tried tires at 35 45 50 psi still bounces. built another set solid and tires at 60 pulled today and this is the worst its been. Should we build a set to allow little more than 1" travel put tires 60 or above? any other ideas or suggestions appreciated thanks!
