I bought this shock to improve the ride of my Vulcan 900. It did just that, having a better spring & rebound adjustment improved the overall ride (no more pogo stick/bucking off the seat).
As for install, very easy (took just minutes). Setting the sag adjustment is an issue. The spanner tool sent is worthless trying to adjust this shock installed. You just can’t get to the adjusting rings while installed. Removed the shock several times to make the adjustment. Finally did get the sag adjusted.
