Go ahead and stock up on bump stops. I went through three sets in two trips after getting my leaves to flex to their maximum potential. Might even consider air bumps cause they won't wear out when the axle pushes on them. My issue ended up being when one bump was utilized while that side was fully "stuffed". The bump stop was getting compressed at such a bad angle that the stresses were just as much lateral as vertical, so the material would get torn right off of its mount.I figure I have about 4" of up travel and 10 down as well, 2" seems very minimal but looks like that's about where I'll be.
