I bought a set of 12" with 125lbs springs. Installed on a 2012' Road Glide Skunk with a sidecar. AMAZING Improvement. Bought from him in Sturgis.
http://www.terrycable.com/Ultra-Low-Rear-Shocks_c_7.htmlHe started me with 150lbs springs and told me to ride them for a day and see if the were too stiff. They were a bit stiff and he offered to change them out to 125 lbs. I couldn't be happier. I put 2000 miles on them around Sturgis and on the way home. They are worth every penny. I have a Legend Air Ride on my 92' Softail with Sidecar and they are great...but I do not need adjustability on this bike and they are a vast improvement over the stock springs.
Examples: They don't "whoop" and bounce over wavy roads like the stock. One "bounce" and they settle in. The rig also doesn't "wiggle" in turns or "sag" during really aggressive riding/cornering. Terry is great to deal with and really understands his product. Even with very little experience with sidecars he used logic and his experience to make some great decisions on what would work. I HIGHLY recommend these shocks.
They are a great value, look good, and perform as advertised!
