Monroe Shock Absorber (MPN: 557045)

Durable nitrogen gas charged shock for trucks and vans

The Monroe Shock Absorber is engineered for midsize and full-size trucks and vans, providing firm control while maintaining ride comfort. This shock absorber features a nitrogen gas charge that enhances tire-to-road contact, improving overall ride quality and handling by minimizing aeration and shock fade. The heavy-duty nitrocarburized rod and sintered iron piston contribute to its durability, ensuring a longer service life through reduced wear and friction.

With a larger bore and a 2-inch reserve tube, this shock absorber holds more oil, allowing for efficient operation and controlled ride dynamics. The full-displaced valving on compression cycles is designed to deliver a consistent and stable ride, making it suitable for demanding driving conditions. The OE all-weather fluid is formulated to withstand extreme temperatures, further enhancing performance and reliability.

This specific model features a 23.39-inch extended length and a 14.43-inch compressed length, making it a precise fit for vehicle-specific applications. The monotube internal design and non-adjustable valving ensure straightforward installation and operation, while the absence of a boot simplifies maintenance.
