KYB SM5450 Suspension Strut Mount Kit - Front or Rear

KYB SM5450 Strut Mount Kit Overview

KYB SM5450 is a suspension strut mount kit built for front and rear applications on select Jaguar XF and Jaguar S-Type models. It replaces worn vibration insulators and bearing components that can add noise, harshness, and steering looseness to the suspension.

As part of KYB Mount Components, this kit focuses on OE-style replacement fit and suspension function for Jaguar XF and Jaguar S-Type service work.

Key Features

• OE-quality replacement strut mount for application-specific fitment
• Superior rubber helps reduce noise, vibration, and harshness
• Mount bearings support smoother steering response and front-end alignment retention
• Front bearing plates serve as steering pivots and support vehicle weight
• Matched-grade studs and nuts for proper component matching

Detailed Product Information

The KYB Mount Components line is focused on restoring suspension isolation and steering feel with replacement parts engineered for the vehicle application. The SM5450 strut mount kit is designed to replace hardened or worn mount insulators that can transmit road impact into the cabin and affect steering precision. On Jaguar XF and Jaguar S-Type platforms, the mount and bearing assembly plays an important role in ride control, alignment stability, and steering smoothness.

This part cross-references Gabriel 143242 for the same application. KYB SM5450 is a direct-fit suspension service part for 2000-2008 Jaguar S-Type, front and rear, and 2009-2015 Jaguar XF, front and rear, with insulator and boot mount components noted in the fitment data.

What It Helps Address

• Clunking or knocking from worn strut mount insulators
• Excess vibration and road noise entering the cabin
• Harsh suspension response over bumps and rough pavement
• Steering bind or reduced steering smoothness from worn mount bearings
• Front-end alignment drift related to mount wear

Installation Notes and Tips

Install the KYB SM5450 on the correct axle position listed for your vehicle: Fits 2000-2008 Jaguar S-Type, front and rear; Fits 2009-2015 Jaguar XF, front and rear. Verify the existing mount style, insulator, and boot configuration before service, and inspect the strut assembly, bearing plate, and surrounding suspension hardware for wear during replacement.

Because strut mounts affect steering pivot action and alignment, a professional alignment check after installation is recommended whenever suspension components are replaced.

Quality Assurance

KYB is known for OE-focused suspension replacement components, and the SM5450 follows that approach with application-specific design, rubber isolation, and bearing support intended to restore original suspension behavior on Jaguar XF and Jaguar S-Type models.
