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.
