I am looking at getting a set of progressive 422's for my 03 night train that I run about 1 to 2 inches lowered. I was wondering if these shocks are worth the money? Also how hard are they to lower an raise and adjust the rebound? I have lowering bolts in my shocks right now.

 

IMO Yes they are worth the money.

Rebound is not adjustable, Spring Preload and ride height are adjustable

New units have Heavy Duty Spring Option and Remote Adjustable Preload (RAP), but it only tweaks one shock so I'm not a big fan RAP.

I just put them on my 2010 Lo in combination with a set of RaceTech Gold Valve Emulators up front, they're very nice and worth the money.. raising and lowering the manual shocks is as simple as turning 4 nuts..i haven't had to set the preload on mine yet, mostly because i don't understand what i would want to set it to..but even at the setting they're on now, the ride is much nicer and handling in the corners is noticably different.

I was lucky though, got a set of 422's with 1,000 miles on them for $200 on eBay

 

I just installed 422 and progressive drop in on the front on 07 standard. Huge difference and handles much better. Haven't had to adjust yet but is easy.

 

My personal opinion, is if you already have it lowered, save the $500 and put it towards Shotguns.
