KYB Suspension Strut Mount Kit P/N:SM5250

$48.99

Description

Smooth out a harsh, noisy rear ride with the KYB strut mount kit (SM5250), a direct-fit replacement for the listed BMW applications. As the original vibration insulators harden with age, they transmit road impacts, noise and vibration into the vehicle; this rear strut mount kit's fresh rubber cushions those impacts to help quiet and settle the ride while helping locate the strut at its mounting point.

It fits many vehicles, among them the 1997-2001 BMW 740i, 1997-2003 BMW 540i and 2000-2003 BMW M5. See the "Vehicles it fits" section for the full list and engine-level fitment details.

Superior rubber: reduces noise, vibration and harshness compared with old, hardened insulators.
OE-quality components: replacement parts designed for each application to help optimize suspension performance.
Matched-grade studs and nuts: included for installation.

Frequently Asked Questions

What is the KYB suspension strut mount kit SM5250?

It is a rear strut mount kit that replaces worn, hardened strut mounts. Its rubber cushions road impacts to reduce the noise, vibration and harshness that tired mounts pass into the vehicle.

Which vehicles does the SM5250 fit?

It fits many vehicles, among them the 1997-2001 BMW 740i, 1997-2003 BMW 540i and 2000-2003 BMW M5. See the "Vehicles it fits" section for the full list and engine details.

What is included in this kit?

The kit uses superior rubber for reduced noise and vibration, and includes matched-grade studs and nuts for installation.

What are signs a rear strut mount may need replacing?

Added noise, vibration or harshness felt in the cabin, or cracked/hardened mount rubber. Have the cause diagnosed first, since these signs can have other sources.

Should I replace the mounts on both sides?

Replacing the mounts on the same axle together is recommended for a balanced, even ride, since both sides typically wear at a similar rate.
