KYB Front Strut Mount Kit for Mitsubishi

KYB SM5988 is a front suspension strut mount kit for select Mitsubishi Eclipse Cross, Outlander PHEV, and Outlander applications. It replaces worn vibration insulators and bearing components that can transmit noise, harshness, and steering looseness into the cabin.

• OE-quality replacement for front strut mount and bearing service
• Helps reduce suspension vibration, road noise, and impact harshness
• Front bearing plate supports steering pivot action and wheel alignment stability
• Built for Mitsubishi Eclipse Cross, Outlander PHEV, and Outlander front suspension applications
• Part number SM5988 for direct catalog lookup

Product Details

KYB Mount Components are engineered as application-specific replacement parts for the front suspension. On vehicles such as the Mitsubishi Eclipse Cross and Mitsubishi Outlander, the strut mount and bearing assembly plays a key role in isolating road shock while allowing smooth steering movement. When the original mount hardens or wears, the result can be clunks, vibration, and reduced steering precision. KYB SM5988 addresses those issues with a replacement mount and bearing assembly built for the listed front applications. This part cross-references Monroe Shocks & Struts 172286 for the same application.

• Alignment instability caused by deteriorated mount components

Installation Notes and Tips

Install SM5988 on the front suspension only for the listed Mitsubishi applications. Inspect the strut assembly, spring seat, and related hardware condition before reassembly, and verify alignment after replacement. Because the front bearing plate affects steering pivot movement, proper seating and torque are important for consistent handling.
