KYB SM5404 Rear Lower Strut Mount Bushing

KYB SM5404 is a suspension shock absorber / strut mount bushing built for rear lower applications on select Honda and Acura models. It replaces worn vibration insulators that can transmit road harshness, noise, and looseness into the cabin.

For drivers searching for a KYB strut mount bushing for 2001-2011 Honda Civic or 2006-2011 Acura CSX rear lower suspension service, this part is built to restore a tighter, quieter feel at the mount point.

Key Features

• OE-quality replacement strut mount component for application-specific fitment
• Superior rubber construction helps reduce noise, vibration, and harshness
• Mount bearing design supports smoother steering response and front-end alignment retention where applicable
• Matched-grade studs and nuts for proper service replacement

Product Details

KYB Mount Components are built around the needs of the original suspension layout, and SM5404 follows that approach for rear lower mounting service. On worn vehicles, hardened or deteriorated mount bushings can create clunks, excess vibration, and a less controlled ride. This KYB replacement helps restore the isolation and support expected from the suspension mount point. It is a practical choice for Honda Civic and Acura CSX owners addressing rear lower mount wear during suspension repair.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
