Pro Comp Pro Runner Monotube Shock Absorber ZX2021

Pro Runner Monotube Shock
Gas charged monotube design delivers superior performance
Brushed and Zinc plated, clear coated monotube body eliminates performance-robbing cavitation
Dissipates heat more efficiently

The new line of Pro Runner Monotube Shocks are designed specifically for late model trucks, Jeeps and SUVs. 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.
