What vehicles does the Monroe 171321 Quick-Strut fit?
It's a front suspension strut and coil spring assembly for the 2002-2003 Ford Explorer and 2002-2003 Mercury Mountaineer. See the Buyer's Guide tab to confirm fitment for your vehicle.
Do I need a spring compressor to install this?
No. The 171321 ships as a single, fully assembled unit with the upper strut mount, coil spring, and strut preassembled, so no spring compressor is required for the strut replacement.
Is this a complete strut and coil spring assembly?
Yes. It includes the preassembled upper strut mount, application-specific coil spring, and strut in one unit — an all-in-one solution that includes the required components for front strut replacement.
Will this restore my vehicle's ride height?
The coil spring is calibrated to the OE design to help restore ride height and support the vehicle's weight, so it's engineered to return the front end toward factory ride height when the worn strut is the cause.
What interchange numbers does the 171321 replace?
It cross-references LS5390271B and 33FD1113.
