However, it proved to be too expensive as a retrofit, and it was decided that no further cures were forthcoming from the factory. They also stated that the Tundra was a 1/2 ton truck that was really designed to compete with the other 3/4 ton trucks in regard to load capacity, hence the stiff rear springs. So I guess we are "screwed" and have no hope for a factory cure. I have also tried adding 150lbs. to the rear bed as well as lowering air pressure but the ride is still unacceptable at least for me. What I am going to attempt next is to talk to the "experts" at a company here in San Diego called National Spring who custom fabricate suspension components for the Baja off-road crowd. Perhaps they could suggest if cutting or replacing one of the springs or fabricating a totally new set of softer springs would solve the problem. Will let you know what transpires and what they suggest, if anything.
