I had to go and take a look at this for myself! The full text states:

"Premium Ride, Hand-Adjustable Low Touring Shocks

Experience the ultimate in superior ride quality with these premium Low Touring shocks. These shocks utilize a single tube, nitrogen charged design that offers enhanced compression and rebound damping when compared to the air-adjustable Original Equipment or ProfileŽ Low shocks. This provides a plush, controlled ride with reduced chance of bottoming. The compression and rebound damping is split between the two shocks - compression on the right and rebound on the left. This design balances the load of each shock; stiff spring with rebound damping on the left and soft spring with compression damping on the right. Larger chambers with 40mm-diameter pistons and 14mm rods allow these shocks to react more quickly to impacts. This keeps the tires tracking while minimizing harshness transmitted through the frame. A simple **** behind the left saddlebag allows the rider to conveniently modify the spring preload via a hydraulic adjuster."

To this bear with simple brain the swingarm must have remarkable torsional stiffness to control the wheel with a different setup on each side. That or some black magic is involved!

 

what ever they are they have to be better then the stock crap on my RG.

 

I have a set that came on my 2010 Road Glide. Someone bought a 2010 Street Glide and they swaped the shocks with mine. I never could figure out how they worked until they listed them for sale. The dealer couldn't tell me either. To me they are no big deal and not worth the money. I'm still not sure how they work. I'd just as soon have air shocks. The only good thing about them is I didn't have to pay for them. My bike seems to ride fine with them and I've had that **** all over the place. I can make it ride rough as hell.

 

I have no idea how they work, but Wifey and I went on a demo ride two-up last year on a CVO Street Glide and it rode way better than my '08 Ultra. Never bottomed out and handled better than any other bagger I have ridden solo or two-up, and I have ridden quite a few as I have attended many Demo Days and ridden as many different bikes a time would allow. I have actually thought about getting them for the Ultra, but don't know if they would bolt up to pre-'09 frames. H-D says they won't but that doesn't necessarily mean they won't work.

 

I'm fairly certain I have read of HDF members swapping 09 shocks to earlier models. Where there is a will there is a way! Frankly I reckon there are superior shocks out there for similar or better money, so wouldn't buy factory shocks as replacements.

 

I was at the dealer today talking seats since I sold my russell and was looking at the sundowner.

Anyway the reason was to get closer to the ground. The dealer mentioned these shocks and said they will lower you about 1/2 inch that combined with the new lower seats is the solution for the 09 and up height issue

 

It's for when you spend to much at the dealer and your wallet is empty you can compensate for it.

 

so you have these shocks? looking for more experience with people who own them
