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

Part Number: 3.1132G

Summary: The Energy Suspension Auto Trans Mount is engineered to replace short-lived OEM rubber mounts that are prone to failure under torque stress. Featuring Hyper-Flex™ Polyurethane, this mount provides a Black performance finish while ensuring the component lasts 5 to 10 times longer than conventional rubber. By utilizing a patented metal safety locking feature, it effectively controls torque and prevents drivetrain movement, offering the perfect balance of street-friendly vibration absorption and racing-grade durability.

Features

• Patented Metal Safety Interlock: Unique interlocking design provides added confidence against drivetrain and chassis damage to ensure the mount resists problematic torque forces.
• Hyper-Flex™ Polyurethane: High-performance material provides resistance to under-vehicle fluids like oils and coolants to ensure long-lasting performance and durability.
• Chrome Plated Steel Bracket: Heavy-duty steel construction provides a rugged mounting point to ensure proper driveshaft angle and prevent unexpected powertrain damage.
• Vibration Absorption: Specialized polyurethane formula provides a soft enough feel for street use to ensure vibrations are absorbed while remaining rugged enough for competition.
