Thanks GaryNJ I will be calling them about that valving & the springs !

Versy when you get a minute could you double check that spring number !
I'm pretty sure mine has a different number I will check when I get home!

Thanks to everyone for the info

Info about the shocks kinda vague on their website , vague to me anyways

Thought it would work but the shocks never moved unless I had a passenger . The word HARLEY means something totally different as it is set up from Progressive.

Ya never know I may not like the lighter springs if it affects the front end adversely!

I have a set of Progressive shocks on my sportster with the aluminum bodies and adjustable rebound and the preload is set on lightest setting and they are kinda stiff but the Harley needs that ! It handles well for what it is. The RYCA handles very well but when pushing it hard in corner I get a tiny bit of pushing with front end which could be the stiff shocks , but most likely the dual purpose tires but that's going into a turn waay too fast and being on the edge of control. Ridden normally ya know just kinda fast , I have no complaints , rides like its on a rail.

Do you have a recommendation for a suitable spring rate , bike 308 lbs , fat azz 180 lbs , ball park figure is fine ! Remember I like it somewhat stiff

All 11"

shock p/n spring p/n rate travel
412-4005 03-1310B/C 90/130 2.02
412-4233 03-1313-30 115/155 2.02
440-4022 03-1313-20B/C 115/155 2.22

For my... broad shoulders, 115/155 is just right.

I had the 4005's on the 5th preset and it wasn't enough.
The 4022 has threaded preset, I assumed it was on low when I got it, haven't adjusted it ever.

remember, the shocks sit at an angle.
this will increase the force they see by about 1.4

80/100 will work well. The stiffness comes from the damping.

Wasn't enough what? Spring? Preload (too much sag)?

"Firmness" is more a function of damping then spring rate. The preload adjuster doesn't change the rate of the spring, it adjusts the sag.

My hip pockets were dragging and my butt was bouncing off the stops.
And as you noted earlier, these are progressive springs, increasing the preload, increases the bottom spring rate.

Too much sag = not enough spring.

BTW, Ruttly's bike is probably 60-70pounds lighter than a typical LS, with a large portion of that weight loss over the rear axle. His spring requirements are different than a stock bike and vastly different than one that has been dressed up.

Weigh the bike, weigh the rear, weigh it enough ways to know What load the shocks see. Otherwise you are guessing and shooting in the dark,,well, with a night lite,
