Ok, I have a 2007 Street Glide, stock shocks, 1" lowering brackets. I am 5'8" 330 lbs and have been bottoming out ever since the lowering brackets have been installed. I checked the psi, and they were at 10?! I have some friends with bag gets but they are all over the map, 15, 17, 21, 25, 35......what is a good starting spot?

 

I would think you would run the same pressure as before you put the brackets on. Are the shocks bottoming or are you binding or bumping the bracket?
They list it in the owners manual. Here it is for an 09 Ultra.

 

Because your already running the lowered Street Glide shocks & lowering blocks (which is bad on every level), I suspect your gonna need to be pretty close to the max 50 psi. Maybe start at 40, if it's still hitting, give it 50.

 

===========

Adding 1" lowering blocks to your already 1" lower HD isnt a good thing to do IMHO.

10psi isnt near enough & can sure add to a shocks bottoming out issue.

Well because your starting at 330lbs rider wt I'd start at 30-35psi & go from there,max is 50psi for 09 bikes.

Wife & myself combined wt is approx 315-320lbs and riding 2up i run 35-40lbs with bags empty or lightly/partially loaded .

Riding 2up with bags & bike fully loaded i run 48-50lbs.

Good luck.

Agreed. With the lowering blocks you are giving the swing arm more leverage on the shocks. That being said not sure you can carry anything approaching the recommended load on the bike without bottoming out or interfering with rear suspension travel. Low looks cool but has it's own set of problems.

 

So many better options than lowering brackets. Seats, tires, and even boots with thicket soles. You don't have to totally sacrfice comfort for dropping it a little.

 

I still have the stock shocks on the bike, the only reason I lowered it was to be able to put both feet flat on th ground when stopped. I might just go with the heavy duty lowered shocks rather than the brackets, but the brackets were only 40 bucks!

 

Go here: https://www.harley-davidson.com/cont...rs-manual.html and see what HD recommends for your model in stock configuration for shock air pressure...

 

Air it up Dude!
Try 50 psi, try a ride with it, and see if you are able to back it off any.
Be sure to use a small manual pump, don't try an air hose from a compressor.
Not much volume to the system, be easy with it.

 

I use my air tank from when I was racing. Put whatever pressure I want in the shock and then hit it. No worry about too much. I changed mine out now so that's in the past, but it works. I also carry a tube jumper to go from tire to tire in an emergency, works for shocks too.
