Monroe 65165 Suspension Shock Absorber - Rear

Monroe Magnum Shock Absorber 65165 Overview

The Monroe Magnum Shock Absorber 65165 is a gas-charged, large-bore suspension shock absorber for Class 6-8 trucks. It is built for air spring and taper leaf suspensions, where fast response and consistent damping matter under heavy load and high mileage.

For heavy-duty truck suspension service, Monroe 65165 combines nitrogen gas charge response with an extra-large piston bore to help maintain control in demanding operating conditions. This Magnum Shock Absorber line is focused on commercial-duty suspension performance for vehicles that see frequent road use and severe service.

What It Helps Address

• Excessive bounce or oscillation in heavy truck suspension systems
• Reduced damping control from worn shock absorbers
• Harsh or inconsistent ride behavior under load
• Suspension instability in air spring and taper leaf applications
• Service replacement needs on Class 6-8 commercial vehicles

Installation Notes and Tips

Verify upper and lower mounting codes before installation: LS47 loop bushing and sleeve mount with 9/16 in. sleeve ID and 1.5/8 in. sleeve OAL. Confirm compressed length, extended length, and travel length against the existing shock to ensure proper suspension geometry. This Monroe Magnum Shock Absorber 65165 uses a metal dust shield and does not list a compressed bumper stop, extended bumper stop, or extended hydraulic lockout.

Compatible With heavy-duty truck suspension service where Monroe Magnum Shock Absorber 65165 dimensions and LS47 mounting match the original unit. For vehicle-specific applications, confirm the exact make, model, and suspension configuration before ordering.
