Welcome. I may be wrong but I'm pretty sure those stock shocks would need to be changed.

 

Thanks. That is what I was thinking!

 

Yes you would need different shocks I assume.
Make make sure to keep the shocks properly inflated. It's in the owner's manual.
Since I ride 2up all the time I keep it between 45 and a maximum of 50.
If you let the air go too low the shocks can bottom out and be damaged and if you use a powerful air compressor to inflate them I think you can blow out the seals.
I play it safe and I bought the Harley air shock pump. Works great.
I know a lot of people don't but I actually like the stock shocks.
This is the pump I bought if the link works I'm doing this from my phone. If it doesn't just Google Harley air shock pump. It's like 50 bucks.

Do not use a compressor on the air shocks. You'll blow them out. HD sells a low volume hand pump. Get one and use it to inflate your shocks.

 

We make a compressor kit that works with the stock air shocks. Let's you rise or lower the shocks with fingertip control...while at a stop or while riding.

See it HERE.

 

That is a very interesting kit. But on further thinking, the stock shocks don't raise or lower with pressure changes, so I'm curious how the system raises and lowers stock shocks.

DO NOT USE A AIR HOSE OR COMPRESSOR on your shocks

Use on a low volume pump

 

Yeah this, the shocks hold a very small amount of air, don't use compressed air on them ever.

 

Not sure why you think that the factory shocks don't raise or lower with pressure changes. There was a video in the link I posted showing that they do. Here it is....Even though this video is showing a Tri-Glide, it is the same with ALL HD factory air shocks...they all will raise and lower like this. (check it out at the 33 second mark)It is true, you do not want to use a typical compressor on it...they will blow out. But a compressor, like in this KIT, with the regulator that comes with it, works just fine.
