The Pro Runner Monotube shocks deliver the most bang for your buck when combined with the new Pro Runner Control Arms. At the heart of the shock is the gas-charged monotube design that delivers superior performance compared to traditional twin tube shocks. The brushed and zinc-plated, clear coated monotube body is nitrogen gas pressurized to eliminate performance-robbing cavitation during compression and rebound. This allows the shock to dissipate heat more efficiently. The Vehicle Specific Ride Tuning (VSRT) in each shock was derived using extensive dyno and real world testing. The result is multi-stage valving to optimize the ride and handling characteristics for each application. Whether you are towing a trailer or hitting woops in the desert, you can count on Pro Comp Pro Runner monotubes to give you the confidence behind the wheel.
