The Aldon shocks can be returned to the factory and they will revalve them if you want different dampening that can't be obtained by the adjusting screw(s) on top and or bottom. Also screwing the threaded spring perch upwards will raise the ride height without changing the stiffness of the ride until the shock is fully extended then continuing to screw it up the shock body will stiffen the ride as static spring height continues to be reduced. Much like shiming the valve springs on a cylinder head.

Many different spring rates are available.
