Pro Comp PR2133 Pro Runner Monotube Shock Absorber

The Pro Comp PR2133 Pro Runner Monotube Shock Absorber delivers superior performance for late model trucks, Jeeps, and SUVs through its advanced gas-charged monotube design. Unlike traditional twin-tube hydraulic shocks, this monotube construction provides better heat dissipation and more consistent damping performance across all driving conditions.

Key Features:

• Nitrogen gas-charged monotube design eliminates cavitation during compression and rebound
• Multi-stage valving optimized through extensive dyno and real-world testing
• Vehicle-specific ride tuning balances comfort and handling characteristics
• Brushed zinc-plated body with clear coat finish for corrosion resistance
• Enhanced heat dissipation reduces shock fade during demanding use
• Consistent performance whether towing trailers or off-road driving

The monotube design allows this shock absorber to dissipate heat more efficiently than conventional twin-tube shocks, drastically reducing performance fade during extended use. The nitrogen gas charge maintains consistent damping force by preventing aeration of the shock fluid, ensuring reliable performance from daily driving to aggressive off-road conditions.
