Energy Suspension Auto Trans Mount Black for 1977-1978 GMC G15

Energy Suspension Auto Trans Mount Black for 1977-1978 GMC G15

Part Number: 3.1108G

Summary: The Energy Suspension Auto Trans Mount is engineered to replace original, short-lived rubber mounts that are often too soft for high-performance demands. By utilizing Hyper-Flex™ Polyurethane material, this mount provides a durable solution that lasts 5 to 10 times longer than conventional rubber components. Finished in Black, this mount is designed to absorb vibrations for street use while remaining rugged enough for racing or off-road applications. It ensures enhanced drivetrain stability and better power transfer by effectively controlling torque forces.

Features

• Patented Metal Safety Interlock: A unique interlocking feature provides added confidence against drivetrain and chassis damage by resisting problematic torque forces.
• Zinc Plated Steel Bracket: Heavy-duty steel construction with a zinc plated finish provides superior strength and corrosion resistance for added durability.
• Hyper-Flex™ Polyurethane Material: This special formula material is resistant to under-vehicle fluids such as oils and coolants and lasts 5 to 10 times longer than conventional rubber components.
• Limited 7 Year or 750,000 Mile Warranty: Provides long-term peace of mind and reflects the high-quality engineering of Energy Suspension components.
