They are made, but they are way up there in price (i.e.; Reigers are ~$9K a set) for the REAL, fully independently adjustable (vs. the cheap 'all in one' adjusting both rebound and compression at the same time, 'coils') 2 and 3/4 way adjustable dampers for our rides.
The KW V3s are about the closest thing to an 'affordable', sort of independently rebound and compression adjustable, coil over setup for our rides.
