What vehicles does the Monroe 37133 fit?
It's a front shock absorber for the 1997-2002 Ford Expedition, 1997-2003 Ford F-150, 1997-1999 Ford F-250, and 2004 Ford F-150 Heritage. Check the Buyer's Guide tab to confirm your vehicle.
Is this a front or rear shock?
This is a front suspension shock absorber, as cataloged for the listed applications.
What does the nitrogen gas charge do?
The nitrogen gas charge helps maintain tire-to-road contact by reducing aeration and shock fade, which supports improved ride and handling.
How many should I buy?
This listing is for one shock. Shocks wear together, so replacing both fronts as a matched pair is recommended for balanced, even ride control.
What are signs my front shocks may need replacing?
Excessive bouncing, nose dive under braking, poor handling, uneven tire wear, or a leaking shock body can indicate worn shocks. Diagnose the cause before replacing.
