Stock shocks are the worst, try either Progressive or Works

 

Progressive 416's 13" use 40 PSI air, they are designed for 80 PSI. You won't believe the ride !!!

I have the 940s on my 07 SE Ultra. Nice ride. Took a little time to dial
them in, but worth it.

 

Hey I deal with this stuff all the time. The H-D stock shocks are good for a few years of riding two up,but to get that bike to ride and handle as it was intended to you need the Progressive 416's mentioned earlier. It's the Best shock out there. How much air pressure would be determined by riders and luggage weight. Also I see alot of low air pressure in tires. People just don't check them till it's obvious there low. I've had them come in my shop with handling complaints thinking they had major problems and it's only low tire pressures. I'll probably get some flack on this but if you run 40 psi in your tires they will last much longer. I've got a guy who helps me in the shop and he got 23,000 miles out of a set of Dunlops that came on his 2008 Ultra and all we did was make sure the tires maintained 40 psi. He's got 10,000 on a set of Avons now. I know tire manuf. say this and H-D says that but trust me on this it hasn't failed me in over 30yrs of owning H-D's

 

Most all of the Progressive shocks are great, however on a bagger you may want the 416 air shock because of the ever changing loads and weight on the bike. It's easier to add air than remove the bags and make mechanical adjustments hoping you have the right adjustment for the load.

The progressive 416 shock has "variable valving" meaning a big bump in either direction gets a lot of dampening and a small bump gets a little dampening. They also use more air up to 80 PSI. Once you determine the load requirements you normally carry and know the air pressure to be in the middle of the stroke, you simply add 5 PSI for each additional 50# of weight and keep the great ride and handling of this shock. Once properly adjusted they do not bottom out very easily.

I have had the same 416's on two different bikes for over 20,000 miles and they are rebuildable. Just sent my 416's to progressive and they rebuilt both for $50. (one had a lower seal leak after 20,000 miles) I put the stock HD shock's back on while they were being rebuilt and could not believe the harsh ride, never could get the right amount of air for my passenger and they were always bottoming out. Once you have the Progressive's on your bike you won't go back the the HD shock.



My .02 worth.
