GM LARGE 7.5 C-C TRANS M NT

The GM LARGE 7.5 C-C TRANS M NT from Energy Suspension is a heavy-duty transmission mount engineered for GM truck platforms that demand superior vibration isolation and durability. This hyperflexible polyurethane and steel assembly replaces worn OEM mounts that fail under load, restoring smooth power delivery and reducing drivetrain noise transmitted through the chassis. Mechanics and truck owners rely on this mount to eliminate transmission clunk, improve shift feel, and extend the service life of transmission internals by absorbing shock loads that stock rubber bushings cannot withstand.

Energy Suspension's Hyper-Flex polyurethane compound offers significantly higher durability than factory rubber while maintaining controlled compliance—essential for trucks running modified engines or heavy towing. The interlocking steel reinforcement prevents lateral deflection during acceleration and deceleration, keeping the transmission precisely centered in the engine bay. With a 7.5-inch transmission bolt span, this mount accommodates the mounting geometry of large-displacement GM truck transmissions. The cadmium-plated steel hardware resists corrosion in harsh underbody environments, while the red polyurethane formulation is visibly robust and designed to withstand extreme temperature swings and repeated load cycling.

This transmission mount is ideal for truck owners who've experienced transmission mount failure—a common issue in high-mileage or modified GM trucks where engine torque exceeds OEM component limits. Installation is straightforward for any mechanic with basic hand tools and a jack; the kit design ensures correct alignment without custom fabrication. Compatibility is confirmed for GM truck applications with the specified 7.5-inch center-to-center bolt span; verify your vehicle's transmission mount configuration before ordering to ensure proper fitment. Whether you're addressing a clunking transmission mount or upgrading for increased reliability under heavier loads, this Energy Suspension mount delivers the performance and longevity serious truck builders expect.
