68-84 Gm 4wd Trans Mount

The 68-84 GM 4WD Trans Mount from Energy Suspension is a critical chassis component engineered for truck builders and serious off-road enthusiasts who demand durability and precision from their powertrain support systems. This transmission mount isolates engine vibration while maintaining geometry that preserves driveline angles—essential when running heavy-duty 4WD applications, towing setups, or modified powerplants. Whether you're restoring a classic K5 Blazer, upgrading a C10 with modern horsepower, or maintaining factory specifications, this mount delivers the compliance and longevity that polyurethane compounds provide over deteriorated OEM rubber.

Energy Suspension's Hyper-Flex polyurethane formulation resists oil, UV, and ozone degradation that degrades rubber mounts within 5–7 years, ensuring this 68-84 GM 4WD Trans Mount maintains consistent bushing stiffness across thousands of miles and extreme temperature swings. The single-bolt attachment design simplifies installation while the polyurethane-steel composite construction distributes engine loads evenly, reducing transmission case stress and preventing the gear-whine amplification common in aged rubber isolators. Weighing 4.48 lbs with compact dimensions (5.2 x 3.8 x 9.9 inches), the mount integrates seamlessly into factory GM truck architecture without clearance conflicts on frame-mounted transmission crossmembers.

This transmission mount is ideal for owners of 1968–1984 GM full-size 4WD trucks—including K5 and K10 Blazers, Suburbans, and pickup platforms—where transmission mount wear accelerates durability concerns under load-carrying or off-road use. Installation requires only basic hand tools and knowledge of transmission crossmember access; the cadmium-plated steel fastener resists corrosion in underbody environments. Pair this mount with a complete drivetrain refresh for maximum effectiveness, or install as a standalone upgrade to eliminate clunking on takeoff and extend the service life of related driveline components. Backed by Energy Suspension's reputation for polyurethane durability, this 68-84 GM 4WD Trans Mount is the right choice for builders seeking OEM-compatible reliability with modern material science.
