SO FAR I LIKE THESE SHOCKS, THEY GIVE A BETTER RIDE THEN THE AIR SHOCKS THAT CAME ON MY ULTRA.

jsadler

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.

The shocks are very awesome . My Electra Glide handles like a dream

hoona88

bought for a bike i worked on the rider loves them

WingsFan47

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.

bkdahlmeier

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

statik9480

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

samsherrill

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.

epooh1

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

Vettnik4

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

shermacord

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

lawson81

Great!!

keith3982

I love the Shocks....they look good and work great

Prozak69

Look GREAT, Quick & Easy 30 minute install!

andrewduncan202

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

Ironwulf

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.

hharris2

Super, and fast shipping!

Cepnoy

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

howzat

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.

outsider58

I love my new shocks....

fishnjeeps

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

Dalty52

So far so good, I was sceptical about buying these shocks for my VTX 1300c because a lot of guys say that they are junk. I'm 260 and my lady is 150 and we had about 60-70 pounds of clothes and camping gear on the bike last week and we put on close to 2000 miles, I had the preload set on the 4th setting and it was super smooth compared to the 55,000 mile old stock shocks.

Important Product Notes

Note: When shocks are shorter than stock, clearance must be carefully checked for potentially dangerous interference.

Note: Standard Duty shocks are for ride loads under 225 lbs., Heavy Duty shocks are for ride loads regularly over 225 lbs.
