KYB Suspension Strut Mount P/N:SM5457

$39.99

Description

Quiet a harsh, noisy rear corner with the KYB strut mount SM5457, a direct-fit replacement for the 1999-2003 Mazda Protege. This rear right suspension strut mount cushions the impacts from road bumps to reduce the jarring, noise and vibration that old, hardened insulators transmit into the vehicle, helping restore a settled ride at the top of the strut.

Superior rubber: reduces noise, vibration and harshness at the mount.
OE-quality replacement: designed specifically for the application to optimize suspension performance.
Cushioned mounting: replaces old, hardened vibration insulators that let bumps ring through the body.
Matched grade studs and nuts: included for a secure connection at installation.

Fits the 1999-2003 Mazda Protege in the rear right position — see the Buyer's Guide tab for engine-level details. Sold individually; if you're addressing worn mounts, inspect the opposite side and replace in pairs for balanced ride quality. A KYB strut mount kit approach — servicing both sides at once — is common practice on this vintage of vehicle.

Frequently Asked Questions

What is the KYB strut mount SM5457?

It's a rear right suspension strut mount that replaces the old mount at the top of the strut. It uses superior rubber to reduce noise, vibration and harshness on the 1999-2003 Mazda Protege.

Where does this KYB shock mount install?

It installs in the rear right position on the 1999-2003 Mazda Protege, seating at the top of the strut where the assembly attaches to the body.

What are the signs this strut mount may need replacing?

Clunking or knocking from the strut top over bumps, added ride harshness, and noise or vibration transmitted into the body can be signs the rubber insulator has hardened. Diagnose the cause before replacing.

Does this KYB top mount include the hardware?

Yes. It comes with matched grade studs and nuts for securing the mount during installation.

Should I replace the KYB strut top mount in pairs?

This listing is for one mount, sold individually. Replacing both sides together is recommended for balanced ride quality, though it isn't strictly required.
