Pro Comp Pro Runner Monotube Suspension Gas Shock Absorber

The Pro Comp Pro Runner is a nitrogen gas-charged monotube shock absorber line engineered to deliver a genuine performance upgrade over conventional twin-tube hydraulic shocks. Designed specifically for trucks, Jeeps, and SUVs, the Pro Runner series applies race-proven monotube technology with platform-specific tuning to provide consistent, confident damping across a wide range of driving conditions — from daily commutes to demanding off-road use.

At the heart of every Pro Runner shock is an internal floating piston (IFP) that physically separates the hydraulic oil from the nitrogen gas charge. This architecture eliminates cavitation during compression and rebound cycles, preserving damping consistency and allowing heat to dissipate more efficiently — dramatically reducing fade under sustained or heavy-duty conditions.

Each shock in the Pro Runner line undergoes Vehicle Specific Ride Tuning (VSRT™), developed through extensive dynamometer testing and real-world validation. The result is application-optimized multi-stage valving that balances ride quality and handling for each intended platform — not a one-size-fits-all adaptation.

Key Features:

• Nitrogen gas-charged monotube design outperforms traditional twin-tube hydraulic shocks by eliminating cavitation
• Internal floating piston (IFP) separates oil from the gas charge for consistent, fade-resistant damping
• Vehicle Specific Ride Tuning (VSRT™) derived from extensive dyno and real-world testing
• Multi-stage valving optimizes ride quality and handling for each specific application
• Enhanced heat dissipation maintains performance under sustained and heavy-duty operating conditions
• Advanced wiper seal design ensures long-term, leak-free performance
• USA-manufactured to world-class production standards
• Backed by Pro Comp's lifetime warranty on suspension products including shocks

Whether towing on the highway, navigating daily roads, or pushing hard on the trail, Pro Runner monotube shocks deliver the damping precision and durability that serious truck, Jeep, and SUV owners demand.
