Q & A

What's in the Box

These black polyurethane motor mounts for S/B and B/B Chevy are much stronger than OE rubber mounts but still reduce vibration.

  • Limits unwanted movement thereby putting more power to the wheels
  • Tough like solid metal mounts without the vibration and noise
  • Resistant to oil, chemicals and road contaminants that typically deteriorate rubber
