Actually,, if you pull out your old springs, cut about 2 to 3 inches off of them, then make a PVC spacer that is 2 or 3 inches longer than the stock one (depending on how much spring you cut out) you will have stiffer springs. Cut the spring from the tigher coiled end since stock springs are progressive, then heat the last coil with a propane torch and push it flat. A little work with the grinder will finish the job. clean it good, reinstall with some fresh oil, and enjoy stiffer spring without throwing away $100 to someone else.
How it works. by cutting the spring you reduce the number of active coils. the fewer active coils, the more force is spread out amoung the remaining coils, coils only get stiff because of torque, fewer coils, same torque equals stiffer spring.
