Product Details

The Monroe Magnum line is focused on commercial-duty suspension control, with shock absorbers sized for the loads and road conditions common in medium- and heavy-duty trucks.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Excessive bounce after bumps or rough pavement
• Reduced damping control in high-mileage truck suspension systems
• Harsh ride behavior in air spring or taper leaf setups
• Suspension instability during repeated load changes
• Wear-related shock replacement on heavy-duty commercial vehicles

Installation Notes

Verify upper and lower mounting style before ordering: both ends use a loop bushing and sleeve mount, with a 5/8 in sleeve ID at the lower mount and a 5/8 in sleeve ID at the upper mount. Confirm compressed length, extended length, and travel length against the vehicle’s suspension geometry before installation. For fitment-based searches, use the exact vehicle application data supplied for your truck or chassis.
