Monroe 65552 Suspension Shock Absorber - Rear

Monroe Magnum Shock Absorber 65552 Overview

The Monroe Magnum Shock Absorber 65552 is a gas-charged, large-bore suspension shock built for class 6-8 trucks using air spring and taper leaf suspensions. Its nitrogen charge supports quick damping response, while the oversized piston bore is built for high-mileage, severe-duty service.

For heavy-duty truck owners searching for a Monroe 65552 shock absorber or Monroe Magnum shock absorber 65552 for class 6-8 suspension service, this part is engineered for consistent control under demanding road conditions. It is also a relevant replacement choice for Four Seasons 65552 cross-reference applications.

Detailed Description

Monroe Magnum 65552 is a passive shock absorber designed for heavy-duty suspension systems that need stable damping and repeatable control. The center-of-loop upper and lower measuring points, loop bushing and sleeve mounts, and 5/8 in.-16 mm sleeve IDs make it a direct-fit style solution for applications that use these mounting dimensions. Monroe Magnum shock absorber 65552 is built to handle the demands of high mileage and severe use without sacrificing response.

This part cross-references Four Seasons 65552 for the same application.

What This Shock Absorber Helps Address

• Excessive bounce or oscillation in heavy truck suspension
• Reduced damping response on worn suspension systems
• Harsh ride quality from fatigued shock components
• Loss of control over repeated road impacts
• Wear-related instability in air spring and taper leaf setups

Installation Notes and Tips

Verify upper and lower mount codes, sleeve dimensions, and overall length before installation. Confirm that the compressed length, extended length, and travel length match the vehicle’s suspension geometry. Because mounting hardware is not included, reuse or source the required hardware separately as needed. For fitment-based searches, this Monroe 65552 shock absorber is a direct match for compatible heavy-duty truck suspension applications rather than a universal part.

Quality Assurance

Monroe Magnum shocks are engineered for commercial-duty suspension service with a gas-charged design and large-bore piston architecture. The Monroe Magnum Shock Absorber line is positioned for class 6-8 vehicles that need consistent control in severe-use environments.
