Monroe 911335 Shock Absorber - Rear

Monroe Reflex Light Truck Shock Absorber 911335

The Monroe Reflex Light Truck Shock Absorber 911335 is built for rear suspension control on higher-center-of-gravity trucks. It uses ASD valving technology that responds to changing road inputs to help manage body motion and keep the ride composed.

Compatible with 2015-2020 Ford F-150 rear applications, this Monroe shock absorber supports stable handling on a full-size pickup platform. The Reflex Light Truck line is focused on controlling roll and dive while maintaining predictable damping for everyday driving and load-carrying use.

Detailed Description

Monroe 911335 is a Reflex Light Truck Shock Absorber engineered for rear use on the 2015-2020 Ford F-150. The Reflex Light Truck product line is aimed at trucks with a higher center of gravity, using valving that reacts to suspension movement to help control pitch and body roll. Mounting is specified as LS39 at both ends with loop bushing and sleeve construction, making it a direct-fit suspension shock absorber for the listed application. This part cross-references Rancho RS55316 for the same application.

What It Helps Address

• Excessive rear-end bounce over uneven pavement
• Body roll during cornering or lane changes
• Nose dive and rear suspension instability under braking and load transfer
• Reduced damping control from worn rear shocks
• Ride inconsistency on a Ford F-150 rear suspension

Installation Notes and Tips

Verify rear fitment against the vehicle’s year, trim, and suspension configuration before installation. Match the upper and lower LS39 loop bushing and sleeve mounts to the existing hardware layout, and confirm compressed and extended lengths against the original shock absorber. For best results, inspect surrounding suspension components for wear before replacing the shock.

Quality Assurance

Monroe backs this shock absorber with a limited lifetime warranty on the listed Ford F-150 application.
