Keep your Ford truck's front end planted and controlled with the Monroe OESpectrum Front Suspension Shock Absorber 37131. This front shock installs as a direct-fit replacement for the 1997-2002 Ford Expedition, 1997-2003 Ford F-150, 1997-1999 Ford F-250, 1997-2001 Ford F-100 Ranger, 1998-2002 Lincoln Navigator, and 2004 Ford F-150 Heritage. Monroe's OESpectrum light-truck damper is designed to restore original factory drivability while filtering out impact-related noise, vibration, and harshness. See the "Vehicles it fits" section for the full engine-level fitment.
- Exceptional handling: full-displaced valving tuned to the vehicle adjusts to road extremes, and a larger bore provides more efficient damping control for a smooth, consistent ride.
- Control and durability: a PTFE-banded piston seals consistently between the piston and pressure tube for better control and increased durability.
- Reduced NVH: the Twin Technology Active Control System helps isolate impact-related noise, vibration, and harshness under most driving conditions.
- Improved ride: a nitrogen gas charge helps maintain tire-to-road contact by reducing aeration and shock fade.
Signs a front shock may need replacing include excessive bouncing, front-end dive under braking, poor body control, and cupped or uneven tire wear. Backed by Monroe's Limited Lifetime Warranty and Feel the Difference Guarantee.
