quality product


Installed on a 2000 FXDL. HD shocks allow for no preload on for a solo 210lb rider. Excellent fit and finish.


pefect fit gave my 2005 Lowrider much better handeling and control over the bunps even with the wife and the bags


I purchased these new shocks for my wife's bike on her birthday. She loves them. Thanks to the helpful tech info I was given before making the purchase.


Wish I installed these years ago.


Extremely happy with the very fast delivery all the way here to Australia beautifully finished shocks and they have improved my handling on my 2007 FXDC superglide 100% thank you :)


Love the look and ride


I installed these shocks on my 05 sportster over the winter the weather finally broke I love the ride and my wife rode with and the shocks performed great so much better than stock shocks great price great job J&P


I put these on a 1998 Sporster 1200C. I am 6'3" and about 240 lbs. The difference is night and day. No more bottoming out and my ride is actually safer now. My rear tire sticks to the road better while accellerating through corners that are bumpy.


I sent them back because they were to mushy and didn't work.


Easy to install. Definite improvement over the stock Sportster shocks.


Nice Shocks, These shocks look great on my Harley and it rides much, much better. Thank you J&P Cycles.


These shocks look great on my bike and it rides alot better too. Would recommend.

Important Product Notes

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