Thank you MarkT, so how do you like the 444's?
Don't have a lot of road miles on them yet. I got the std length, with HD springs. A bit harsh compared to my 416 air shocks but of course they would be. Also that's with the OEM Dumflops at whatever high pressure the last owner used, before I replaced the rubber with Michelin DS, lower pressure and cushier ride. I set the 444's at lowest preload while I'm at 270# so I'm no lightweight. Put wifey on the back w/o changing the preload, she's about 130; we bottomed out some. For the ride back, dialed up the preload I guess 2 clicks. (Couldn't be sure, I used a strap wrench and couldn't feel any clicks). Ride was good then but probably could find a better setting with more experience with it. I expect to be happy with it, but too early to report on it.
They have bushings in the kit for various fittings; intended for HD's I think. I had to cut down one in length on the lathe and IIRC might have drilled it slightly on the drill press. (Don't recall, I do stuff like that quickly w/o thinking about it) No biggy but I'm well tooled. Other tools could have been used.
