Energy Suspension Auto Trans Mount Red for 1979-1990 GMC G3500

Part Number: 3.1108R

Summary: The Energy Suspension Auto Trans Mount Red is engineered to replace short-lived OEM rubber mounts that often fail under torque stress. Utilizing proprietary Hyper-Flex™ Polyurethane, this mount provides a performance-oriented solution that is soft enough for street use while remaining rugged enough for racing or off-road applications. This Red performance-styled mount is designed to last 5 to 10 times longer than conventional rubber components, ensuring long-term drivetrain stability and protection against vehicle fluids. By maintaining the proper drive shaft angle, it helps prevent premature wear and unexpected power train damage for your GMC G3500.

Features

• Patented Metal Safety Interlock: A unique interlocking design provides added confidence against drivetrain and chassis damage to ensure the mount effectively controls problematic torque forces.
• Zinc Plated Steel Bracket: Heavy-duty steel construction with a zinc finish provides superior strength and corrosion resistance to ensure maximum durability under the vehicle.
• Hyper-Flex™ Polyurethane Material: This high-performance material absorbs vibrations for street use while remaining rigid enough for competition to ensure it lasts 5 to 10 times longer than conventional rubber components.
• Fluid Resistance: The specialized polyurethane formula is resistant to oils, coolants, and road contaminants to ensure the mount does not rot or deteriorate like factory rubber.
• Limited 7 Year or 750,000 Mile Warranty: Provides long-term peace of mind and reflects Energy Suspension’s commitment to quality assurance and component longevity.
