Features

  • Performance polyurethane (Hyper-Flex™) engine mount set - sturdier and longer-lasting than stock rubber mounts
  • Balanced design: soft enough to dampen vibrations for street use, yet strong enough for hot-rod, racing or heavy-duty applications
  • Resists degradation from oils, coolants, road contaminants - ideal for older GM trucks and restorations
  • Torque-resistant interlock design - handles high engine/transmission torque loads without excessive flex
  • Improves throttle response and power delivery by reducing engine movement under load or acceleration
  • Reduces engine vibration transmission and improves NVH (noise, vibration, harshness) compared to worn-out rubber mounts
  • Direct-fit replacement for OEM early-generation GM engine mounts - no frame or mount modification required for listed vehicles

Product Description

The Energy Suspension 3.1156G Engine Mount Set is engineered to upgrade classic GM full-size trucks, pickups, vans and SUVs of the 1963-1972 era - including Chevrolet C/K series, Blazer, Suburban, and GMC equivalents. By replacing the original rubber engine mounts with durable Hyper-Flex polyurethane, this kit improves engine stability under load, reduces unwanted movement, and extends mount life significantly over standard rubber. It is well suited for street restorations, hot-rod builds and classic truck projects where longevity and performance matter.

With its torque-resistant interlock design, 3.1156G ensures reliable power transfer even under increased engine torque, while still absorbing engine vibration for everyday drivability. Because the mount set is a direct bolt-on upgrade for compatible early-generation GM chassis, installation is straightforward - no frame modifications are required. This makes 3.1156G a practical, performance-oriented solution for owners looking to preserve classic drivability, restore vintage vehicles, or build strong foundation for modified engines or heavy-duty use.

Whether you're restoring a 1965 Chevrolet C10, building a 1970 GMC Jimmy, or maintaining a '68 Suburban, Energy Suspension 3.1156G offers a reliable upgrade over aging rubber mounts, combining durability, performance, and daily-drive comfort in a single kit.
