I think it’s not so much out smarted as it is different technology driven by engineers building towards different requirements
for example the shocks used in BP51 are adjustable for compression and rebound whilst OEM ones aren’t. That expands the truck to new needs, adjustability, that weren’t be addressed in OEM specifications.
another example is handling on road. Toyota requirements and tolerances probably did not think of people like me that drive every vehicle in a spirited manner. Consequently there is body roll and nose dive with spirited driving. The OME upgrade (seems to going by the repeats of those who are running BO51) addresses a use case Toyota did not anticipate or want to cover.
