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.
