Energy Suspension Auto Trans Mount Red for 1977-1978 GMC K25 Suburban

Part Number: 3.1106R

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. Utilizing Hyper-Flex™ Polyurethane material, this mount provides a Red performance aesthetic while ensuring a lifespan 5 to 10 times longer than conventional rubber components. Designed for the 1977-1978 GMC K25 Suburban, it offers the perfect balance of being soft enough for street use to absorb vibrations while remaining rugged enough for racing or off-road applications. This mount significantly improves drivetrain stability by controlling torque and maintaining proper drive shaft angles.

Features

• Patented Metal Safety Interlock: A unique interlocking design provides added confidence against drivetrain and chassis damage to ensure the mount resists problematic torque forces.
• Zinc Plated Steel Bracket: Heavy-duty steel construction with a zinc finish provides corrosion resistance to ensure long-term structural integrity under the vehicle.
• Hyper-Flex™ Polyurethane Material: This special formula performance material provides superior resistance to oils and coolants to ensure it lasts 5 to 10 times longer than conventional rubber components.
• Torque Control Engineering: High-strength polyurethane provides the rigidity needed to maintain proper drive shaft angles to ensure protection against unexpected power train damage.
• Limited 7 Year or 750,000 Mile Warranty: Provides long-term peace of mind and quality assurance for your GMC K25 Suburban.
