45-48lbs you should be good with the stock shocks depending on combined weight. They will still bottom some and may be a little stiff at high pressures. I went with Ohlins #3-3 from Motorcycle Metal. They are a longer, better performing shock. When I am off the bike it definitely sits taller than stock but when I sit on it the sag is such that I can flat foot it easily. The adjustment is easy. She has a degenerative disc problem and is very happy on the bike now.

 

interesting thread, i ahvce been running way too low pressure in my shocks i didnt know the 09 and up needed that much air, ill be bumping it up tonight

 

I am surprised u havent felt it. My 12 SG came from HD with 9lbs in it and it killed the old lady on bumps.

 

I have a 2013 Street Glide and it will jar your teeth when you hit a average bump. Been working on changing air pressure but haven't found sweet spot yet. Have a friend with a 2007 Street Glide, we swapped rides and went over same bump, night and day difference in the ride, his was pretty smooth. Really like the ride and the handling but damn it's tough on bumps.

 

Go visit motorcyclemetal.com they will set you up w the best shocks for your bike, even tell you straight up what you need, don't and what others who claim to be the best, actually aren't.

 

started at 40+ per the manual, now 32-35 two up and loaded, comfortable. sure it bottoms out occasionally in a dip, but it does not feel like no shocks at all solid with 40+

 

On my 2012 Road Glide Custom, I run 20 lbs solo and 40 lbs when riding with my wife and gear. I am 180 lbs and wife is 130. We have tried every setting and this is best for us.
I also run a sundowner seat which is much more comfortable for her and also for me. I like my riding position of the stock seat better than the sundowner but it is really a better all day seat.
We rode 8 hours yesterday and felt great after getting home.

I think a combination of seat and shock settings will get you and a passenger comfortable. I can say just a few pounds can make a difference in how it handles and feels.
You just have to chase it down to get it to where you want it.

 

+1 on motorcycle metal... I think 12" JRI B's will suit you well. A newer "low" touring seat will give you the other inch.

 

I run about 28 lbs solo on my 09 SG to feel comfortable. I weigh about 175 lbs.

Ohlin's for rear if you can afford them, but if you want to address both the front and the rear do Progressive 940's or 944's in the rear, and Progressive Monotubes in the front.
Those 2 items are about the same price as the Ohlins which will only address the rear.

Do the front when you change out to the chrome front end.
It's only another $300. LOLOL..
