KYB SM5203 Front Strut Mount for Infiniti QX4 and Nissan Pathfinder

KYB Strut Mounts eliminate the vibration and noise caused by old, hardened vibration insulators. They optimize suspension performance by offering OE quality replacement components designed for each application. KYB Strut Mounts cushion the impacts from road bumps to reduce the jarring effect, noise and vibration that old mounts transmit into the vehicle. Front bearing plates are the steering pivots and support vehicle weight. They are critical to steering performance and wheel alignment. KYB Strut Mounts and bearing plates have a reputation for providing the highest quality in the industry.

• Matched grade studs and nuts

Restore smooth suspension operation and dependable steering response with the KYB SM5203 Front Strut Mount. Designed as an OE-quality replacement component, this strut mount helps eliminate the vibration, noise, and harshness commonly caused by worn or hardened original mounts. It cushions impacts from road bumps while helping maintain the suspension performance expected from a properly functioning strut assembly.

On applications equipped with a front bearing plate, the mount supports the vehicle’s weight and serves as a steering pivot during turning. Because these components influence steering performance and wheel alignment, replacing worn mounts can help improve ride quality, reduce unwanted suspension noise, and support consistent handling. KYB engineers each mount for application-specific fit and performance, making the SM5203 a practical replacement for the front suspension.
