Product Details

The KYB Mount Components line focuses on restoring the function of worn suspension mounting parts with application-specific replacement design. SM5051 is used in rear-at-shock knuckle bushing locations and is built to help isolate road impact before it reaches the cabin. On vehicles such as the 1986-1997 Honda Accord, 1988 Honda Civic, 1986-1990 Acura Legend, and 1997-1999 Acura CL, this part supports a quieter, more controlled rear suspension feel.

This part cross-references Monroe Shocks & Struts 906915 for the same application.

Common Problems This Part Can Address

• Rear suspension noise from hardened or deteriorated bushings
• Excess vibration transmitted into the vehicle body
• Harsh impact feel over bumps and rough pavement
• Reduced steering precision caused by worn mount-related components
• Alignment instability related to worn front-end support parts on applicable systems

Installation Notes and Tips

Verify the rear-at-shock position and compare the original bushing dimensions before installation. For best results, inspect adjacent suspension hardware and mounting points for wear, corrosion, or damage that could affect the new component. Professional installation is recommended for accurate suspension service and proper fitment on the listed Acura and Honda applications.
