The "Nitro 9000" line of shock absorbers incorporates self adjusting "Velocity Sensitive Valving". This revolutionary technology varies the resistance valving incoporated in the shock according to piston rod speed. This allows for a super smooth highway ride and outstanding control in rugged off-road situations from the same shock, without turning any knobs or shock removal for re-adjustment. Heckethorn shocks are tuned "To Operate At Peak Efficiency" and offer ultimate ride quality when partnered with Hell Creek Suspension systems. For the best possible ride, always use Heckethorn shocks when installing our Suspension Kits or Systems.
PLEASE NOTE: Shock boots are no longer supplied, as they shorten the life of the shock by trapping dirt and moisture.
