Product Details

The Monroe Magnum line is aimed at heavy-duty suspension service where consistent damping matters. Part number 66897 uses a gas-charged internal design to improve response and help maintain a more controlled ride under load. The metal dust shield helps protect the shock body, while the extended hydraulic lockout supports control at full extension. This makes the Monroe 66897 a practical choice for rear suspension service on Chevrolet G30, Ford E-350 Econoline, and Dodge B300/B350 platforms with the specified Neway tag axle setup.

This part cross-references Monroe Shocks & Struts 172286 and 182286 for the same application.

What This Shock Absorber Helps Address

• Excessive rear-end vibration
• Worn shock performance that reduces ride control
• Unstable handling on heavy-duty rear suspension setups
• Premature tire wear caused by poor damping
• Downtime tied to suspension wear in commercial use
