progressive 440 adjustment....
just installed a set of prog 440 heavy duty shocks on my road king. i cannot for the life of me find any information about a "suggested" preload for specific weights. anyone?? starting from a ballpark area is easier than starting from zero! fyi, me and the mrs are around 400 lbs total plus a tour pak. figure 420...430?

Careful putting too much preload on those shocks.... The thing that made me get rid of them was their propensity to "top out" when ya go over an elevated section of road (like in an intersection, some bridges, & railroad crossings). The damn things extended so fast and hard that they would BANG at full extension. It was like they had zero rebound dampening.

I would turn them to full light load then start with two full turns toward a stiffer ride and adjust from there. I think you can adjust them about 6 full turns between soft to stiff ride.

That's how I ended up doing it, working up from 0 in 1/2 turn increments...

Forgot to mention this earlier, it's been awhile since I set mine up. Chock the front wheel upright and have someone measure the sag with both of you on it and a typical load in the bags. Adjust the preload to get a moderate amount of sag (mine is 1/2 or 1", I forget), THAN start test riding and fine tuning.

Roughly the same weight situation here as you mentioned in your post. Me along = no pre-load (full counterclockwise), me and the honey, turn it two indents on the cap. Could maybe go a third but never really felt I had to try it.

thanks guys! i actually got a response back from progressive pretty quick too. they suggested to go two "lines" down with a passenger...which equates to about 6 revolutions. i had it at 7 turns at the start of the day, and i experienced that "top out" twice. so i lowered it to 5 turns and was very very pleased with the ride. little stiff, but that works for me.
i tell you, changed the fork oil to 20 wt at the same time...it was like a brand new bike!! 20k miles...it was time for an update.
