Cushion road impacts and quiet the vibration that old, hardened insulators transmit into the vehicle with the KYB strut mount kit SM5123. This suspension strut mount kit drops in as a direct-fit replacement for many vehicles, among them the 1995-1999 Nissan Maxima, 1991-1996 Infiniti G20 and 1993-2001 Infiniti Q45 — see the "Vehicles it fits" section for the full list.
KYB strut mounts are engineered to OE quality for each application and address the noise, harshness, and jarring ride that worn mounts create. On front applications the bearing plate serves as the steering pivot and helps support vehicle weight, so it is critical to steering performance and wheel alignment.
- Superior rubber: reduces noise, vibration, and harshness from old, hardened mounts.
- Mount bearing: provides smoother steering and helps retain front-end alignment.
- Front bearing plate: acts as the steering pivot and helps support vehicle weight.
- Matched grade studs and nuts included for installation.
If a worn strut mount is the source of your ride noise or vibration, this kit replaces it. Replacing the mounts on both sides together is recommended for a balanced ride and handling.
