Monroe 911132 Shock Absorber - Rear

Monroe Reflex Light Truck Shock Absorber

The Monroe Reflex Light Truck Shock Absorber, part number 911132, is built for rear suspension service on select Ford trucks with a higher center of gravity. It uses ASD valving technology to react to changing road inputs and help control body roll and nose dive.

• ASD valving adjusts damping response to road impact changes
• Rear shock absorber for light truck suspension applications
• Metal dust shield included for added protection
• Upper stem mount with 3/8"-16 thread pitch
• Lower loop bushing and sleeve mount with 12 mm sleeve ID
• Extended length: 23.875 in; compressed length: 14.25 in
• Travel length: 9.625 in

Reflex Light Truck Series Details

Monroe Reflex Light Truck Shock Absorbers are tuned for trucks that sit higher and carry more dynamic load transfer during braking, cornering, and uneven-road driving. This Monroe 911132 shock absorber uses automatic damping adjustment to respond to impact changes, helping maintain more controlled rear suspension movement on Ford F-150 Heritage, Ford F-150, and Ford F-100 Ranger applications.

This part cross-references KYB 344374 for the same application.

Vehicle Fitment

• Fits 2004 Ford F-150 Heritage, rear. Except 7,700 GVW.

• Fits 1997-2001 Ford F-100 Ranger, rear. Except 7,700 GVW.

What It Helps Address

• Excessive rear suspension bounce after bumps
• Body roll during lane changes and cornering
• Nose dive during braking
• Loose or unsettled rear ride control
• Worn shock performance on higher-center-of-gravity trucks

Installation Notes

Verify rear fitment by year, model, and GVW before ordering. Confirm the upper stem mount and lower loop bushing and sleeve mount match the vehicle’s original shock configuration. Compare compressed length, extended length, and travel length to the existing shock absorber to ensure proper suspension travel and clearance.

Quality Assurance

Monroe engineers the Reflex Light Truck line for controlled damping response in truck suspension applications. Part number 911132 is built with a metal dust shield to help protect the shock body in normal service.
