$186.99
Settle a sagging rear end and quiet the clunks with the Monroe Quick-Strut Rear Suspension Strut and Coil Spring Assembly (MPN 172747), a fully preassembled complete strut and coil spring assembly. It installs as a direct-fit replacement for the 2004-2007 BMW 525I, 2008-2010 BMW 528I, 2004-2007 BMW 530I, 2008-2010 BMW 535I, and 2004-2005 BMW 545I — see the Buyer's Guide tab for engine-level details.
- Complete, ready-to-install unit: bundles the strut, coil spring, and upper mount in one assembled unit, so no spring compressor is required.
- Restores ride height: the application-specific coil spring is calibrated to the OE design to restore ride height and support the vehicle's weight.
- Vehicle-specific design: application-specific spring, mount, and strut designs are fit checked and ride tested for ride and handling matched to the vehicle.
- Rust resistance: a protective coating resists rust and corrosion.
The preassembled components carry an OE-style design for fit, form, and function, and the premium upper mount helps deliver smooth steering while reducing body sway, vibration, and road harshness before it reaches the cabin. Backed by Monroe's Limited Lifetime Warranty and Feel the Difference Guarantee.

Frequently Asked Questions
What comes in this assembly?
It's a fully preassembled rear unit that includes the strut, an application-specific coil spring, and the upper strut mount — everything needed for the strut replacement in a single unit, with no spring compressor required.
Does this strut assembly fit my BMW?
It's a direct-fit rear assembly for the 2004-2007 525I, 2008-2010 528I, 2004-2007 530I, 2008-2010 535I, and 2004-2005 545I. Check the Buyer's Guide tab to confirm your engine and configuration.
Is this a front or rear unit?
This is a rear suspension strut and coil spring assembly for the listed BMW applications.
Should I replace both rear struts at once?
Replacing the left and right rear struts together as a matched pair is recommended for balanced ride and handling. This listing covers one assembly, so order two for a complete rear replacement.
What are signs my rear struts may need replacing?
Excessive bouncing, body sway, a rough or sagging ride, or uneven tire wear can indicate worn struts. Diagnose the cause first; if the original struts are worn out, this assembly replaces them.
