Energy Suspension GM Transmission Mount 3.1108G — Hyper-Flex Polyurethane Direct-Fit, Durable

Energy Suspension 3.1108G is a direct-fit GM transmission mount made from durable Hyper-Flex polyurethane to replace OEM rubber mounts and resist contaminants and permanent compression.

This transmission mount from Energy Suspension is designed to be a long-lasting replacement for worn factory mounts on supported GM vehicles. Built in the United States with the brand’s Hyper-Flex polyurethane, the part aims to maintain transmission alignment while resisting oil, coolant, and road chemicals that often degrade rubber. The result is steadier drivetrain support, reduced seasonal softening, and improved longevity compared with conventional mounts.

How does this mount compare to the original rubber GM transmission mount?

Compared with OEM rubber, the Hyper-Flex polyurethane compound resists breakdown from oils and road contaminants that accelerate rubber fatigue. It is formulated to retain shape and damping ability over time instead of compressing or crumbling.

• Polyurethane resists oils, fuels, and brake fluids better than rubber
• Engineered to limit permanent compression under repeated loads
• Maintains transmission position to reduce drivetrain movement
• Manufactured in the United States to Energy Suspension standards

Will this mount affect ride comfort or drivetrain vibration?

The mount is firmer than stock rubber, so you may notice a slightly firmer feel under acceleration or during gear changes, but it is designed to balance durability with vibration control. Energy Suspension’s Hyper-Flex aims to provide controlled support rather than a harsh, jarring transfer of vibration.

• Reduces excessive transmission movement that can cause clunks
• Offers predictable damping without rapid deterioration
• Designed to minimize added noise while improving stability

What are the installation and fitment considerations?

3.1108G is a direct replacement for the specified GM applications, so it installs in the same mounting points as the original part. Basic mechanical skills and standard hand tools are typically sufficient; if you are unsure, a professional install ensures correct torque and alignment.

• Direct-fit for compatible GM transmission mounting locations
• Bolts to existing brackets using OEM hardware or supplied fasteners
• Recommended to check vehicle-specific fitment before purchase
• Professional installation advised if access or torque specs are unfamiliar

How long can I expect this mount to last, and what maintenance is required?

The Hyper-Flex polyurethane is formulated for longer service life than rubber in the same conditions. There is no routine maintenance for the mount itself; periodic inspection for cracks, separation, or loose hardware is recommended as part of regular vehicle checks.

• Engineered for extended service life in harsh environments
• No scheduled maintenance beyond periodic visual inspection
• Inspect after severe impacts or extended exposure to chemicals
• Replace if visible wear, tears, or mounting hardware failure occur

Who this product is for: The Energy Suspension 3.1108G transmission mount is aimed at GM owners who want a more durable, longer-lasting replacement than OEM rubber—especially drivers exposed to harsh climates, road chemicals, or heavier driving loads. It suits DIY mechanics comfortable with basic installation and professional shops replacing worn drivetrain mounts that need dependable, contaminant-resistant performance.
