Disappointed
I purchased these to lower my 09' FLHRC and although they do lower the bike significantly there is a large tradeoff in ride quality. I'm only 190 lbs and the only way to keep these from bottoming out is to adjust the preload to it's maximum level which then makes the ride very harsh. If you absolutely have to lower your bike to reach the ground comfortably and don't plan on long rides you can use these without an issue but if you ride 75 miles or more at a time the ride is too severe to make it worth while. I used these for almost two months and Dennis Kirk still gave me my money back minus 10% because of a few scratches. I think their return policy is very fair and I will not hesitate to buy anything from them in the future.

Great addition
Includes all the possible hardware you could ever need. Great ride and handling- just wish they made them in flat black in addition to the gloss black.

Ideal suspension for riding
This suspension is ideal for those who ride.
My wife & I took my 2002 XLH 883 on a 1000 mile in 24 hour ride with the stock equivalent length Progressive Suspension 412 Series shocks.

These shocks slipped right on my XLCR and are a huge improvement over the original shocks. And the price was 30% below the competition.

Progressive 412 shocks
All I can say is they are better than the stock ones, The stock showa shocks aren't the best. These seam to ride better you don't feel the sharp edged bumps as bad, they are even better than the 440 I.A.S shocks that I replaced.
