I personally run Suspension Technologies F-Tech Series Shocks (link below) on my personal Street Glide and feel as though they are a "hidden gem" in terms of a great performing shock at a great price point. However, we (Iron Aces Speed Shop) do have a few customers that have recently purchased the Legend Suspension REVOs. From everything I have heard, they are a very good performing shock that make quite a difference in terms of ride quality over the OE shocks...which are horrible.
Since there are both adjustable and non-adjustable versions of the REVOs (both linked to below), if you did decide to go this route I would encourage you to consider investing in the REVO-A version which does allow you to set the rebound to your riding preference. The only "negative" feedback I have received was from a customer who was kicking himself for not getting the adjustable REVOs since while they did improve the overall ride, he would have liked to have had the option of fine-tuning the rebound to his particular riding style.
