Reflex Monotube Shock Absorber Product Line Details

The Monroe Reflex Monotube Shock Absorber line focuses on delivering reliable suspension damping through a monotube design. This design enhances heat dissipation compared to twin-tube shocks, which helps maintain consistent performance during extended use. The 911503 part number is part of this line, offering a balance of durability and ride quality for Chevrolet C1500 and GMC Sierra 1500 Classic trucks.

This shock absorber features a plastic dust shield that protects the piston rod from dirt and debris, extending the service life of the unit. The lower mounting uses a cross pin mount with a closed-ended 5/16" hole ID, ensuring secure attachment to the vehicle’s suspension. The upper mounting is a stem mount with a 2.3/8" stem length and 3/8"-16 thread pitch, compatible with the specified Chevrolet and GMC models. The travel length of 4.375 inches allows for adequate suspension articulation, while the compressed and extended lengths (10.25 inches and 14.625 inches respectively) fit the factory suspension geometry precisely.
