DENNIS on 10/31/2019

easy install, had to use a vice to get bushing in, but no problem, stiff ride but was told to ride awhile to "break-in"

THOMAS on 10/10/2019

Massive improvement over stock shocks, can’t believe I waited so long

JOHN on 10/2/2019

Excellent ride now Worth the bucks

JOHN on 9/5/2019

Worth the money Trash the air shocks on my 2013 flhx

JOHN on 8/30/2019

Definitely better than the stock air shocks on my flhx

DAN on 7/8/2019

Made a huge difference in the ride and handling. Highly recommend them!

davedavisdal on 2/18/2016

great riding shocks, just wish they had a baseline weight for setting so I didn't have to experiment with settings.

Kpl378 on 8/17/2015

After finding the right adjustment, my bike rides better than ever. I love these shocks

spiglo on 7/8/2015

These are the best shocks out there, a night and day difference in the comfort of the ride

ptmramos on 4/24/2015

Great product. Very happy. Recommend.

Important Product Notes

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