Energy Suspension Auto Trans Mount Black for 1983-1991 GMC S15 Jimmy 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. By utilizing Hyper-Flex™ Polyurethane material, this mount provides a durable solution that resists under-vehicle fluids like oils and coolants while lasting 5 to 10 times longer than conventional rubber components. This Black transmission mount is soft enough to absorb vibrations for street use yet rugged enough for racing or off-road applications. It ensures enhanced drivetrain stability and better power transfer by maintaining proper drive shaft angles.

Features

• Patented Metal Safety Locking Feature: A unique interlocking design provides added confidence against drivetrain and chassis damage to ensure the mount effectively controls problematic torque forces.
• Zinc Plated Steel Bracket: Heavy-duty hardware provides superior strength to ensure long-lasting durability and resistance to road contaminants.
• Hyper-Flex™ Polyurethane Material: This special formula performance material provides a rugged mounting surface to ensure it outlasts OEM rubber and resists degradation from oils and coolants.
• Limited 7 Year or 750,000 Mile Warranty: Provides long-term peace of mind and quality assurance for your vehicle’s drivetrain.
