Monroe 65171 Suspension Shock Absorber - Front

Magnum Shock Absorber Overview

The Monroe Magnum Shock Absorber 65171 is a gas-charged suspension shock built for heavy-duty service. It is engineered for air spring and taper leaf suspensions, with a large-bore design that delivers fast response and consistent control under demanding conditions.

Compatible with International LoneStar front suspension applications, this shock absorber is built for Class 6-8 vehicle use where mileage, load, and repeated road input place extra demand on damping performance. The Monroe 65171 is a direct-fit service part for the specified application and is identified by part number 65171.

Key Features

• Gas-charged design for quick suspension response.
• Large-bore construction for heavy-duty damping control.
• Built for air spring and taper leaf suspension systems.
• Metal dust shield helps protect the shock assembly.
• Loop bushing and sleeve mounts at both ends for the listed application.

Detailed Description

The Monroe Magnum Shock Absorber line is positioned for severe-duty truck suspension service, and the 65171 follows that focus with a nitrogen gas charge and extra-large piston bore. Those design elements help maintain consistent damping when the suspension is working hard over long distances and repeated load cycles. For International LoneStar trucks, this shock absorber matches the listed front fitment and OE reference information, including OE part number 3813340C4.

Part number 65171 also cross-references Four Seasons 85963 for the same application. The Monroe 65171 is a practical replacement choice when the goal is restoring controlled ride behavior in a heavy truck suspension system.

What It Helps Address

• Excessive bounce after bumps or road impacts.
• Reduced damping control in high-mileage suspension service.
• Inconsistent ride behavior under heavy-duty use.
• Wear-related loss of shock response in air spring or taper leaf setups.
• Need for a replacement shock matched to the listed International LoneStar application.

Installation Notes and Tips

Verify the vehicle’s suspension configuration before ordering, including the listed sleeper cab and 14,000 parabolic tapered leaf spring application details. Confirm the upper and lower loop bushing and sleeve mount dimensions against the existing hardware and compare the compressed and extended lengths to the original shock. Fitment for this Monroe shock absorber is listed for International LoneStar front applications from 2009-2020.

Quality Assurance

Monroe designs the Magnum Shock Absorber line for demanding truck suspension service, using a gas-charged, large-bore construction intended for consistent control in severe-use conditions. Part number 65171 is built to the specifications shown for the listed application.
