J&P gave me a good price and good service on this product. I am happy with the ride and quality of the shocks as installed on my 2010 Roadking Classic. I would recommend them.

bought for a bike i worked on the rider loves them

Great shock, great price. These aren’t the most expensive shocks out there, and when you read all the technologies in the higher end shocks, it may seem like that’s the way to go. I ride hard, and my 412’s always give me at least twice as many miles as stock HD shocks.

Easy to install, fit perfectly on my 2009 FXDC. Lowered my bike and kept a reasonably smooth ride 2-up.

shocks came on time, were easy to install and give my dyna a smooth ride.

Got these shocks for my '97 FXDWG. I live in New England where the roads are bumpy and pot holes are everywhere. I and my wife are a ride weight of about 450 together; they shocks can take more. These have really improved her comfort and the handling of the bike. Also the install was a breeze.

Very quick delivery (shipped USA 10/17/14 - arrived in Switzerland 10/23/14) - good price and quality

A lot more comfortable than the stock shocks on my Street Bob for longer rides.

Exactly what I wanted. Price seemed fair. Arrived in a timely manner. Couldn't be more pleased with the service.

Awesome. you wont be dis appointed. these shocks make an old bike ride better than new.

Great looking Shocks. Head the warning on fitment. Too large in diameter to fit on a 1979 Roadster without chain interference. Returning for smaller shocks.

Super, and fast shipping!

* Yeasy install. * Washers rust after first rain * Not safely for your back. Realy bad. Ride such as angry bull

Funny how you become used to shock's that are not doing their job, after fitting the new progressive shock's the ride difference was incredible,great product at the right price.

I love my new shocks....

Installed in 20 min to my 92' Vulcan 88. Even the first cam setting seems like its a bit stiff for single riding. Going 2 up should be so much more comfortable now. We used to bottom out on manhole covers, now no bottoming out. One of the best upgrades I've done to my bike
