Wow wow , there is a flood of messages. This shocks are street shocks , I have never tried them offroad in racing. There was no intent to sell them as race shocks . We used them on XR 75 and Trail bikes thats more the design of them. They work great on road use thats all I know, but you never know . So if you want to race them , you can try , but don't throw them back at me .
