Energy Suspension Auto Trans Mount Black for 1979-1990 GMC G1500

Energy Suspension Auto Trans Mount Black for 1979-1990 GMC G1500

Part Number: 3.1108G

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. Constructed from proprietary 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 applications. By upgrading to Hyper-Flex™ material, this component lasts 5 to 10 times longer than conventional rubber and offers superior resistance to under-vehicle fluids like oil and coolant. This mount ensures enhanced drivetrain stability and better power transfer for your GMC G1500.

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.
• Hyper-Flex™ Polyurethane Material: This high-performance material is resistant to oils and road contaminants and lasts 5 to 10 times longer than conventional rubber components.
• Zinc Plated Steel Bracket: The heavy-duty steel bracket with a zinc finish provides maximum strength and corrosion resistance to ensure long-term durability.
• Torque Control Technology: Maintaining proper drive shaft angles provides protection against early wear to ensure the prevention of unexpected power train damage.
• Limited 7 Year or 750,000 Mile Warranty: Provides long-term peace of mind and stands as a testament to Energy Suspension’s manufacturing quality.

Why Choose This Product?

• Engineering Advantage: Unlike factory rubber mounts that lack a safety locking feature, this mount utilizes a patented metal safety interlock to effectively control torque and protect the chassis from damage. The use of Hyper-Flex™ Polyurethane offers a significant engineering leap over 1950s-era OEM rubber technology.
• Performance Benefit: Drivers will experience improved drivetrain stability and reduced movement without the harshness of a solid metal mount. It is soft enough to absorb vibrations for street use while remaining stiff enough for high-horsepower racing applications.
• Value Proposition: With a lifespan 5-10 times longer than rubber and a 750,000-mile warranty, this mount is a “fit-and-forget” solution that protects expensive drivetrain components from premature wear.

Frequently Asked Questions

Will this improve shift quality?
Yes, by helping to control torque and maintaining the proper drive shaft angle, this mount reduces excessive transmission movement which can lead to more consistent shifting.

Is this mount too harsh for a daily driver?
No, the Hyper-Flex™ Polyurethane is specifically formulated to be soft enough to absorb vibrations for street use while remaining rugged enough for competition.

What makes this better than the factory GMC mount?
The Energy Suspension mount features a patented safety interlock and Hyper-Flex™ material, whereas the factory rubber version typically lacks a locking feature and degrades much faster when exposed to oils and heat.
