Quiet a harsh, noisy front end with the KYB strut mount kit SM5427, a direct-fit front replacement for the 1999-2003 Mazda Protege. Old, hardened vibration insulators let road impacts, noise, and vibration pass straight into the vehicle; this suspension strut mount kit replaces them to cushion those impacts and restore proper isolation at the top of the front strut.
Fits the front position on the 1999-2003 Mazda Protege. See the Buyer's Guide tab for engine-level details.

What vehicles does the KYB strut mount kit SM5427 fit?
It is a front-position strut mount kit for the 1999-2003 Mazda Protege. Check the Buyer's Guide tab to confirm the exact application for your vehicle.
What does a suspension strut mount kit do?
It secures the top of the strut to the body, isolates road vibration and noise, and its bearing plate serves as the steering pivot while helping support vehicle weight.
What are the signs that my strut mounts may need replacing?
Signs include noise, vibration, or harshness from the front end, stiff or notchy steering, and hardened or deteriorated mount rubber. Diagnose the cause before replacing.
Does this kit include the mounting hardware?
Yes. KYB includes matched grade studs and nuts with the mount and bearing so it fits and torques correctly during installation.
Should I replace both front strut mounts at the same time?
Replacing both sides together is recommended so the front suspension wears and performs evenly. Confirm the quantity needed for your vehicle in the Buyer's Guide.
