Energy Suspension Auto Trans Mount Black for 1979-1990 GMC G2500

Part Number: 3.1108G

Summary: The Energy Suspension Auto Trans Mount is engineered to replace short-lived and typically soft OEM rubber mounts that fail under stress. Built with Hyper-Flex™ Polyurethane, this Black performance mount provides the perfect balance of being soft enough for street use while remaining rugged enough for racing or off-road applications. By upgrading to Energy Suspension, you ensure a component that lasts 5 to 10 times longer than conventional rubber, effectively resisting under-vehicle fluids like oils and coolants. This mount is specifically designed to stabilize the drivetrain and maintain proper drive shaft angles for the 1979-1990 GMC G2500.

Features

• Patented Metal Safety Interlock: The unique interlocking design provides added confidence against drivetrain and chassis damage to ensure the mount can resist problematic torque forces.
• Zinc Plated Steel Bracket: The heavy-duty steel bracket with a zinc finish provides superior strength and corrosion resistance to ensure long-term structural integrity.
• Vibration Dampening: The specialized polyurethane formula provides enough flexibility to absorb vibrations to ensure a smooth street driving experience without the harshness of solid metal mounts.
• Hyper-Flex™ Polyurethane Material: This high-performance material is resistant to road contaminants and oils, ensuring it 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 manufacturer’s commitment to quality assurance.
