I reported few months ago that I installed 444 progressive shocks on my 2013 tri-glide.
Overall still love the ride they give. I originally had them set up on the 2nd ring(they have 4 rings for preload). The other day I decided to back it off to the 1st ring, Well I had to take the wheels off to turn the nut. Not sure if everyone would have to but I am getting older and need pliers to turn the adjuster. Still like the shocks.
