Monroe Reflex Shocks

Signs You Need Replacement

  • Excessive bounce

  • Rear sag under load

  • Instability during braking

  • Uneven tire wear

  • Clunking from rear suspension

If it feels unsettled, it’s time.


Installation Notes

  • Replace rear shocks in pairs

  • Inspect leaf springs and bushings

  • Verify mounting hardware condition

  • Torque to factory specifications

Because worn bushings cancel out new shocks fast.

MONROE REFLEX SHOCKS

Ideal for vehicles with a higher center of gravity, Monroe Reflex shock absorbers feature Acceleration Sensitive Damping (ASD) valving technology that automatically adjusts to absorb road impacts, helping to reduce vehicle roll and dive.

Monroe Reflex Shocks

Monroe Reflex shocks are designed to restore your vehicle’s original drivability and ride performance. Not just for ride comfort, shocks are necessary for the safe handling of your vehicle. By maintaining vertical loads placed up on the tires, shocks help ensure consistent tire-to-road contact. Shocks also help maintain a balanced ride by providing resistance to vehicle bounce, roll and sway as well as brake dive and acceleration squat.

CAUSES & CONSEQUENCES OF SHOCK FAILURE

Like many parts on your vehicle, shocks are subject to wear. Causes include damaged bushings, exposure to the elements, loss of oil viscosity and deteriorated components. Driving with worn shocks can result in problems ranging from reduced braking efficiency, tire wear, loss of stability and damage to other suspension parts.

DIAGNOSING NOISE WITH NEW SHOCKS

If noise is present with a replacement shock absorber, check that the mount is tightened securely and look for other worn suspension parts. Some shock absorbers utilize a “clevis” type mount, which must squeeze the sides of the shock’s “mounting sleeve” very securely in order to prevent noise. Using new hardware and mounting bolts help ensure its tightened securely. Check the brackets to make sure they didn’t get spread apart excessively when the original shock was removed.

Monroe Reflex Shocks

IMPORTANCE OF ALIGNMENT

Always perform an alignment whenever replacement shocks, struts or other ride control parts are installed. Camber, toe and caster settings can all be affected by installing new shocks. Failure to make sure the vehicle’s alignment is within factory specifications can lead to problems like premature tire wear.

HOW TO CONDUCT A SHOCK INSPECTION

Shocks may not show any visible signs of wear, make sure to request a ride control inspection every time your vehicle is brought in for service to ensure they’re in optimal operating condition. When inspecting a vehicle’s shocks: assess how the vehicle is used and perform ride and physical evaluations. Get an understanding of the vehicle’s repair history, the way the vehicle handles and its intended use for clues if the shocks might need changing. Next, take the vehicle for a test drive to determine whether the vehicle’s steering, stopping and stability are compromised. Wrap up the inspection with a physical examination for symptoms of wear which may indicate new shocks are required.

Final Verdict

The Monroe Reflex 911331 Shock Absorber for Ford F-150 offers improved handling and stability over standard OE-style replacements. Ideal for restoring control without sacrificing ride comfort.

Because trucks should feel confident—not floaty.

    Exact OEM factory replacement for my F150. Perfect fit and ride. Truck rides like new again, thanks Monroe! My grandfather worked for Monroe Auto Parts and always talked with pride about their products quality.

    The shocks were fine but I found that shocks were not my problem after I installed and tested them. My bad. Paid for something I didn’t need.

    The shocks were just what the doctor ordered. Softened the bumps and reduced the movement in the truck.

    The eyelets are made in the wrong size.These are supposed to have bushings with an inside diameter of 12mm, but they are much larger than 12mm. No additional bushings are provided. To install the proper size of bolts for these shocks would require me to drill out the mounting brackets on my vehicle; I opted not to hack up my vehicle just to solve Monroe’s manufacturing problem.
