Level out your Buick's front end with the Monroe Quick-Strut Strut and Coil Spring Assembly 171665, a fully preassembled front-corner unit that drops in as a direct-fit replacement for the 1998-2005 Buick Park Avenue and the 1998-1999 Buick Riviera. This all-in-one Quick-Strut arrives as a single, ready-to-bolt-in module, so there's no need for a spring compressor during installation.
- Complete, Ready-to-Install Unit: Bundles the strut, application-specific coil spring, and preassembled upper strut mount into one part, simplifying the front strut replacement.
- Restores Ride Height: The coil spring is calibrated to the OE design to help restore ride height and support the vehicle's weight.
- Vehicle-Specific Design: Fit checked and ride tested with application-specific spring, mount, and strut designs intended to deliver ride and handling suited to this vehicle.
- Corrosion Protection: A protective coating resists rust and corrosion and is salt-spray tested for the elements.
The premium upper strut mount is designed to help maintain smooth steering while reducing body sway, vibration, and road harshness before it reaches the cabin. For balanced ride and handling, it's best practice to replace the front struts as a matched pair. Backed by Monroe's Limited Lifetime Warranty and Feel the Difference Guarantee.

Frequently Asked Questions
What vehicles does the Monroe 171665 Quick-Strut fit?
It's a direct-fit front strut assembly for the 1998-2005 Buick Park Avenue and 1998-1999 Buick Riviera. See the "Vehicles it fits" section to confirm your exact vehicle.
Is this a complete strut and coil spring assembly?
Yes. It arrives as a fully preassembled unit with the strut, application-specific coil spring, and upper strut mount together, so no spring compressor is needed to install it.
Do I need to buy two?
This listing is for one front strut assembly. For balanced ride and handling, it's best practice to replace both front struts as a matched pair, though it isn't strictly required.
Will this restore my ride height?
The coil spring is calibrated to the OE design to help restore ride height and support the vehicle's weight. If worn front struts are the cause of sag, this unit replaces them.
Is the assembly protected against corrosion?
Yes. A protective coating resists rust and corrosion, and the unit is salt-spray tested to help it stand up to the elements.
