Energy Suspension Auto Trans Mount Black for 1985-1986 GMC K3500

Part Number: 3.1129G

Summary: The Energy Suspension Auto Trans Mount is designed to replace short-lived and typically too-soft OEM rubber mounts that fail under torque stress. Engineered specifically for the 1985-1986 GMC K3500, this mount utilizes Hyper-Flex™ Polyurethane to provide a durable solution that is soft enough for street use yet rugged enough for racing or off-road applications. This Black polyurethane component is resistant to under-vehicle fluids like oils and coolants, ensuring it lasts 5 to 10 times longer than conventional rubber components while maintaining proper drivetrain stability.


Features

  • Patented Metal Safety Interlock: A unique interlocking design provides added confidence against drivetrain and chassis damage to ensure the mount effectively resists problematic torque forces.
  • Hyper-Flex™ Polyurethane Material: This high-performance material is resistant to road contaminants and provides superior durability, lasting 5 to 10 times longer than conventional rubber components.
  • Zinc Plated Steel Bracket: Heavy-duty steel construction with a zinc plated finish provides a rugged mounting solution to ensure long-lasting performance in harsh undercar environments.
  • Torque Control Engineering: High-strength design helps maintain proper drive shaft angles to ensure the prevention of early wear and unexpected power train damage.
  • 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 control torque and maintaining proper drive shaft angles, this mount reduces excessive transmission movement which can improve overall drivetrain stability.

Is this mount durable enough for off-road use?
Absolutely. The Hyper-Flex™ Polyurethane and heavy-duty zinc-plated steel hardware are designed to be rugged enough for racing and off-road environments while remaining soft enough for street use.

What is the benefit of the safety interlock?
The patented metal safety locking feature provides an extra layer of protection against drivetrain and frame damage by effectively managing high torque forces that often tear standard rubber mounts.
