Dexter has a performance comparison to standard, Trailair (Equaflex) and Mor/Ryde equalizers
here. If you assume the testing is accurately reported, the Dexter equalizers are the best by far. Also, the Mor/Ryde and Trailair equalizers are worse than the standard OEM all steel banana equalizers. The thick Dexter shackles sure look impressive compared to the rest.
We replaced the Lippert Equa-flex setup that came on our TT with the EZ-Flex equalizers, wet bolts and shackles when we first bought it. We installed shocks at the same time and can't tell how much the Dexter equalizers compare to the Equa-flex ones, but with having the shocks too has really improved the handling and reduced bounce. Our OEM plastic bushings were totally shot in just over 2K miles from the factory to the dealer on the west coast and were glad we installed the new wet bolts from the start.
