Energy Suspension Hyper-Flex polyurethane motor mount inserts are engineered to replace soft, short-lived factory rubber mounts. These inserts provide the durability needed for high-torque racing and competition use while remaining compliant enough for street driven vehicles. Designed as a performance application, they effectively eliminate excessive engine movement to ensure more power reaches the drivetrain.

Many applications feature a torque-resistant safety interlock design, providing strength comparable to solid metal mounts without the harsh vibration transfer. The polyurethane material is chemically resistant to common automotive fluids including oil and coolant, ensuring they won't degrade over time like OE rubber.

  • Manufacturer Part Number: 3.1156G
  • Material: Hyper-Flex Polyurethane
  • Design: Safety interlock for high-torque stability
  • Durability: Resistant to road contaminants, oils, and coolants
  • Application: Performance upgrade for street or track
