What spring fits my shock? The ProRate Spring is currently available for a 50, 52.5, 55, 57.5, 60, 62.5, and 65mm stroke Jade/Jade X shocks. If you have a 50-57mm stroke shock, get the 55mm spring. If you have a 60-65mm shock, get the 65mm stroke spring. If your shock does not have any of the above stroke lengths, the ProRate Spring will NOT work. You need to use the LS spring.
