Energy Suspension Auto Trans Mount Black for 1983-1990 GMC S15 4WD

Part Number: 3.1129G

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 is resistant to under-vehicle fluids like oils and coolants. This mount ensures enhanced drivetrain stability and better power transfer for your GMC S15.

Features

• Patented Metal Safety Locking Feature: 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 formula provides superior durability and performance benefits and lasts 5 to 10 times longer than conventional rubber components.
• Zinc Plated Steel Bracket: The heavy-duty steel construction with a zinc finish provides maximum strength and corrosion resistance to ensure long-lasting service life.
• Torque Control Engineering: 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 quality assurance for your vehicle investment.
