Settle the ride and help keep your Ford truck's rear tires planted with the Monroe Reflex Suspension Shock Absorber 911132, a rear-position shock built for vehicles with a higher center of gravity. It's a direct-fit replacement for the 1997-2001 Ford F-100 Ranger, 1997-2003 Ford F-150, 2004 Ford F-150 Heritage, and 1997-2003 Ford Lobo — see the Buyer's Guide tab for the full engine-level list.
- ASD valving: Acceleration Sensitive Damping technology adjusts to impacts, designed to reduce roll and dive on higher-center-of-gravity vehicles.
- Exceptional handling: Full displaced valving tuned to the vehicle reacts to road extremes, while the larger bore provides more efficient damping control for a consistent, smooth ride.
- Consistent ride: OE all-weather fluid with special additives helps handle extreme temperatures and reduce oil breakdown, and a larger reserve tube holds more fluid to run cooler.
- Control and durability: A Fluon-banded piston keeps consistent sealing between the piston and pressure tube, and a nitrogen gas charge reduces aeration to help maintain tire-to-road contact.
A self-lubricating fluid seal retains gas and reduces friction against the piston rod. Backed by Monroe's Limited Lifetime Warranty and Feel the Difference Guarantee.

It's a direct-fit replacement for the 1997-2001 Ford F-100 Ranger, 1997-2003 Ford F-150, 2004 Ford F-150 Heritage, and 1997-2003 Ford Lobo. Check the Buyer's Guide tab to confirm your vehicle.
What is ASD valving?
Acceleration Sensitive Damping is valving technology that automatically adjusts to road impacts, designed to reduce roll and dive on vehicles with a higher center of gravity.
What are signs my rear shocks may need replacing?
Excessive bouncing after bumps, nose dive under braking, body roll in turns, uneven tire wear, or fluid leaking from the shock body can all indicate a worn shock. Diagnose the cause before replacing.
Is this shock covered by a warranty?
