KYB Suspension Strut Mount P/N:SM5133
Quiet the ride and steer with confidence using the KYB strut mount SM5428, a direct-fit front replacement for the 2003-2004 Mazda 6. It replaces old, hardened vibration insulators that transmit road noise and harshness into the cabin, cushioning impacts from bumps to reduce the jarring effect that worn mounts pass along.
KYB strut mounts and bearing plates have a reputation for high quality in the industry. If a failed or hardened original mount is the source of your front-end noise, vibration, or steering harshness, this is the KYB shock mount that replaces it. Because mounts wear together and share the front axle, replacing both sides at the same time is good practice for balanced steering and even wear.
