Don't know about fixed? I never actually hauled anything real heavy with the 3 leafs that came on the truck origionally. I had the TSB done adding the 4 leaf springs and have since hauled some pretty good weight. I like the way it handles both with a load and without. Don't feel the dealer would have done it to my '08 if it has truley been fixed by beefed up 3 leafs. With the stock TRD shocks my truck was about 2.25" higher in the rear after the TSB.
I added 5100's all around and adjusted the front 5100's to the .85" setting and the rear is still 1.25" higher in the rear, which I like. Set this way with a load it is still level or slightly taller in the rear. Set to the third setting of 1.75 would probably have set my truck exactly level running light. Note that everybody gets different results with the TSB.
