Pro Comp PR2129 Pro Runner Monotube Shock Absorber

The Pro Comp PR2129 Pro Runner Monotube Shock Absorber delivers superior performance for late model trucks, Jeeps, and SUVs through advanced monotube technology and vehicle-specific tuning. Engineered to outperform traditional twin-tube hydraulic shocks, this shock absorber features nitrogen gas charging and multi-stage valving optimized through extensive dyno and real-world testing.

Key Features:

• Monotube design with nitrogen gas charging eliminates cavitation during compression and rebound
• Multi-stage valving provides optimized ride quality and handling for specific applications
• Brushed zinc-plated body with clear coat finish for corrosion resistance
• Enhanced heat dissipation drastically reduces shock fade under demanding conditions
• Vehicle-specific ride tuning derived from extensive testing protocols
• Superior performance for both towing applications and off-road use

Whether you're hauling heavy trailers on the highway or tackling high-speed desert terrain, the Pro Runner monotube design maintains consistent damping performance by efficiently managing heat buildup and preventing performance-robbing cavitation. The result is predictable handling, improved ride comfort, and reliable performance across a wide range of driving conditions.
