1 Ton 4 Wheel Disk and 38x16 TSL\'s stop great- thankfully! I had a scare this morning from an accident which happened right in front of me at about 50 mph where two cars met each other and came to a dead stop (they were ok). The details aren't as important as how fast the truck came to a stop and remained in control, even through momentarily locking the inside rear as I swerved to miss. I've been contemplating getting rid of the big TSL's due to their soft rubber compoind and poor wear characteristics on the road but not any more. Ironicly, the truck stopped so fast I didn't really need to swerve after all. It's been my experience that flexy suspension, big tires and big lift on a heavy truck tend to stop slow... but hydraboost brakes, 1 ton conversion and 14bolt disk really came together for me, maybe the ford 57's soft ride and the anti wrap bar had a bit to do with it too, but they all get a hands down positive review from me, and my 4 year old son (who thought the whole incident was a riot)!
