Monroe Reflex Light Truck Shock Absorber 911334

The Monroe Reflex Light Truck Shock Absorber 911334 is built for rear suspension service on Ford F-150 models with a higher center of gravity. It uses ASD valving technology that responds to changing road inputs to help control body motion and maintain a steadier ride.

Key Features

• ASD valving automatically adjusts damping response to road conditions
• Rear shock absorber for Ford F-150 applications
• Dust shield included for added protection
• Extended bumper stop included
• Loop bushing and sleeve upper and lower mounts
• Reserve tube diameter: 2.251 in.
• Compressed length: 17.28 in.; extended length: 28.78 in.; travel length: 11.5 in.

Product Line Details

Monroe Reflex Light Truck Shock Absorbers are tuned for light truck use, where suspension control matters under load and during everyday driving. This line focuses on reducing roll and dive by adjusting damping response as the suspension moves, which is especially relevant for rear shock replacement on the Ford F-150.

Detailed Description

This Monroe 911334 rear shock absorber is a direct-fit suspension component for 2015-2025 Ford F-150 models listed below. It is engineered for vehicles without electronic adjustable suspension on 2021-2022 applications and is also listed for 2023-2025 rear fitment. The loop bushing and sleeve mount design uses LS39 upper and lower mounting codes, and the unit includes a dust shield and extended bumper stop for added protection in service.

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

What It Helps Address

• Rear suspension bounce after bumps and dips
• Excessive body roll during lane changes or cornering
• Nose dive and rear-end instability under braking and load transfer
• Worn shock performance on high-center-of-gravity light trucks
• Ride control loss on Ford F-150 rear suspension systems

Installation Notes and Tips

Verify rear fitment by model year before ordering: Fits 2015-2020 Ford F-150, rear; Fits 2021-2022 Ford F-150, rear, without electronic adjustable suspension; Fits 2023-2025 Ford F-150, rear. Confirm mount style, compressed length, and extended length against the original shock before installation. Inspect surrounding suspension bushings and hardware condition during replacement to ensure proper operation.

Quality Assurance

Monroe Reflex shock absorbers are built around ASD valving technology to provide responsive damping for light truck applications. Monroe 911334 is backed by a limited lifetime warranty on the listed Ford F-150 applications.
