Product Details

KYB Mount Components focuses on replacement suspension hardware that restores the function of worn upper strut mounts and bearing plates. On vehicles such as the Mazda CX-5 and Mazda 6, the front strut mount is a steering pivot point and a load-bearing component, so wear can affect ride quality, steering feel, and wheel alignment. KYB SM5884 addresses those service needs with a design matched to the original application.

This part cross-references OE-style numbers such as 48609WB001 and B45A3438XA for the same application. The KYB SM5884 part number is also useful when searching for a front suspension strut mount kit for Mazda CX-3, Mazda CX-5, Mazda 3, Mazda 6, Scion iA, or Toyota Yaris iA.

What It Helps Address

• Front suspension noise from hardened or worn mount insulators
• Steering vibration transmitted through the strut tower
• Harshness over bumps and road joints
• Loose or inconsistent steering feel at the front end
• Alignment concerns related to worn mount bearings
