I ordered these to replace the OEM air shocks on my '06 Road King, which were toast. I am 73 yrs old, and have back issues from a wreck years ago. After installing these, I went for a 200-mile cruise and had NO issues at all, and the bike rode like brand new. Highly recommend.

Great shocks, easy install. Lousy packing. Shock box was great but they put it in a larger box and broke open from Louisville KY to Ft Myers FL. Lucky nothing was missing. Need more stock at Daytona location.

I bought these for my 2003 honda vtx 1800r. Taking the original ones off I noticed how wore out they were. I read a lot of reviews on these and wow what a difference in the way it sets. Even setting the steering is so much easier. Thanks jpcycles for getting them here quick. We'll worth the money.
