Firestone Ride Rite
#1
#2
Not exactly the same as you're asking, but I just lowered my '01 SCrew 2"/4". The rear went a lot lower than I expected so I ordered the Firestone airbags and compressor to bring it back up an inch or so. I frequently tow a trailer for the motorcycles so it will come in handy to keep the rear up under load as well. I should have my bags before the end of the week, hopefully get them installed Saturday, and will post back how they work out.
