I have experienced some minimal bed bounce however only at certain speeds. I have also seen a newer f150 with bed bounce on the highway at 70-75mph and I was in the tundra and I had none. I know that all frames have an internal frequency that will make them bounce and the preload of the super springs definitely changes that frequency somewhat fixing the problem. A counter acting damper is the only thing that is going to cure the problem. When ford and chevy claim their frame is stronger I say prove it. Torsionally it may be more rigid but that doesn't say strength if it did the superduty and c/k hd trucks would have boxed frames. They don't and they are a lot stronger than any of their 1/2 tons.The 10.5k tow rating has little to do with the ride. The actual bed payload has more to do with it than anything and ours is one of if not the lowest. The springs may have actually been designed a little soft making for a nice highway ride but not so good for bed bounce on slightly larger bumps. I would like to see if the bed bounce problem occurs mostly on trd or non trd equipped trucks because i believe the trd equipped trucks have a slightly higher spring rate? Either way with the good reviews of the supersprings it looks to me like a little heavier spring may actually reduce the problem. If any tundra owner on here has the bed bounce problem they should be contacting toyota directly to speed up the fix screw going through the dealers it takes too long for a manufacturer to make a change when they hear it second hand.
