I’ve got one with older Nitro UCAs (urethane bushings, & ball joint), one with older SPC UCAs, and one with Trail Tailor UCAs. All of the options that I have are roughly equivalent.
Between Nitro & Dobinsons, I’d lean Dobinsons,mainly due to level of service.
SPC is the most adjustable, but with the limited amount of lift available, I question if it is actually necessary.
@TRAIL TAILOR UCAs are not a stock item, but I believe that Jason does do batches every now and then. Of the different UCA options that I’ve had, these are my favorite. I have 2 spare sets, just waiting for the next time I have to tear into the suspension of the SPC and/or Nitro vehicles.
Couldn’t agree more, mainly for orphaning the UCAs that I have, with no apparent source for replacement bushings.
