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

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

Part Number: 3.1108G

Summary: The Energy Suspension Auto Trans Mount is designed to replace original, short-lived rubber mounts that are often too soft for high-performance demands. Engineered with Hyper-Flex™ Polyurethane, this Black transmission mount provides the perfect balance of being soft enough for street use while remaining rugged enough for racing or off-road environments. By upgrading to this polyurethane component, you ensure a mount that lasts 5 to 10 times longer than conventional rubber components while effectively controlling torque. This mount is specifically designed to maintain proper drive shaft angles and protect your drivetrain from unexpected damage.

Features

• Patented Metal Safety Interlock: A unique interlocking design provides added confidence against drivetrain and chassis damage to ensure the mount can resist problematic torque forces.
• Hyper-Flex™ Polyurethane: High-performance material provides superior resistance to under-vehicle fluids like oils and coolants to ensure long-lasting performance and durability.
• Zinc Plated Steel Bracket: Heavy-duty steel construction with a zinc finish provides corrosion resistance to ensure structural integrity in harsh environments.
• Vibration Absorption: The specialized polyurethane formula provides enough dampening to absorb vibrations for street use to ensure a smooth driving experience without the harshness of solid metal mounts.
• Hyper-Flex™ Polyurethane Material: This proprietary material is engineered for performance 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 Energy Suspension’s commitment to quality assurance.

Frequently Asked Questions

Will this improve shift quality?
Yes, by helping to control torque and preventing excessive movement, this mount helps maintain proper drivetrain alignment which can improve overall stability.

Is this mount too harsh for a daily driver?
No, it is engineered to be soft enough to absorb vibrations for street use while remaining rugged enough for racing or competition applications.

What makes this better than the factory GMC mount?
The Energy Suspension mount features a patented safety interlock and Hyper-Flex™ polyurethane, whereas the factory rubber version lacks a locking feature and is prone to faster degradation from fluids and torque.
