Installed on my 2021 Street Glide Special. Have to say when it says HD Springs they are!Feels more like a Hard Tail then a Bagger. Spring rate is way to heavy, I am a 220 lb rider with 6.5 lid speakers, 8 inch woofers in each bag and carry a lot and still to heavy even set at softest position.Now as looks and fit, yes they fit and was easy to install.Value for money is good, ride quality is pretty harsh, looks good and they do perform, just remember if a light rider and weight, they will be very stiff. Had to order different shocks!

These shocks are amazing. They have great travel for a smoothe ride. It drops about an inch from stock height. I have 6x9s and 8 inch midbass in my bags along with heavy sissy bar and luggage rack and it does not bottom out even riding 2 up. Very happy

Do your research on youtube for your specific application. Requires center jack. There are several bushings and washers for various applications. I personally have 2010 FLHX, which called for one cuffed bushing and one washer. The bushing cuff should face the bike from the backside of the shock. I retained the locking washer on mine from the OEM set-up but replaced the washer with the one provided. I am 5"10" about 200lbs and am starting with the setting at the 3rd stop. After three rides, the ride is more comfortable and I haven't bottomed out yet. Definitely worth the money and effort to install yourself.

I bought these about a mont ago for my 2016 Road Glide. Very easy to install, however I have tried all five settings, and still is NOT a very enjoyable ride. Beats the crap out of me. Any suggestions?

Very nice low profile. Very for me at the factory setting. Rides pretty smooth now for an 11.5" shock.

I was skeptical about ordering these but am very glad I did. I figured the low price meant low quality and a sucky ride but I was wrong. I prefer these to the air shocks. Adjusting them to a heavy load or solo riding is easy, there's never a loss of air to keep fine tuning, and I truly think the ride is waaaaay more comfortable.

The product was great. Good price. They were easy to install. Only problem is the ad didn't say it was a pair - of course I assumed that it was, since you can't buy just one shock......but it should have said 'pair'.
