KYB SM5743 Suspension Control Arm Bushing

KYB SM5743 is a suspension control arm bushing from KYB Mount Components, built for front lower arm at the strut fork applications on select Ram and Dodge Ram trucks. It is made to replace worn vibration insulators that can add noise, harshness, and looseness to the front suspension.

For 2006-2010 Dodge Ram 1500 and 2011-2016 Ram 1500 applications, this KYB SM5743 bushing supports OE-style suspension restoration with the fit and material quality expected from KYB Mount Components.

Key Features

  • OE-quality replacement component designed for the specific application
  • Superior rubber construction reduces noise, vibration, and harshness
  • Mount bearing design supports smoother steering and front-end alignment retention
  • Matched-grade studs and nuts for proper component integration
  • Built to restore suspension performance at the front lower arm strut fork location

Product Details

KYB Mount Components focus on replacing worn suspension mounting parts with application-specific OE-quality components. The SM5743 is engineered for front lower arm at strut fork use on Ram 1500 and Dodge Ram 1500 trucks, where worn bushings can transmit road shock, vibration, and steering irregularity into the cabin. By restoring the mounting interface, this part helps return the front suspension to a more controlled and quieter operating condition. This part cross-references Chrysler part numbers 4877198AA and 55398376AA for the same application.

Common Issues This Part Addresses

  • Front suspension noise over bumps and rough pavement
  • Excess vibration transferred through the chassis
  • Harsh ride feel from hardened or deteriorated mounting rubber
  • Steering looseness related to worn front mount components
  • Alignment instability caused by degraded mount support

Installation Notes and Tips

Verify the vehicle year, make, model, and front lower arm at strut fork position before ordering. Inspect the surrounding suspension hardware and mounting points for wear, corrosion, or damage before installation. Because this component affects steering and alignment geometry, a professional alignment check after installation is recommended.

Quality Assurance

KYB has a long-standing reputation for OE-quality suspension replacement parts, and the SM5743 is part of the KYB Mount Components line focused on restoring original equipment-style performance for the front suspension.
