73-98 GM V8 Motor Mount Black - Each

The Energy Suspension 73–98 GM V8 Motor Mount Black is a precision polyurethane and steel motor mount insert engineered to replace worn OEM clamshell mounts on fourth-generation GM V8 engines. Built for the 4-bolt GM clamshell configuration, this Hyper-Flex insert isolates powertrain vibration while maintaining structural integrity under sustained high-load conditions—critical for both street performance and extended duty cycles where engine movement translates directly to chassis feedback and component wear.

Energy Suspension's polyurethane formulation delivers significantly lower compliance than rubber without the brittleness or temperature sensitivity of early elastomer compounds. The hybrid steel-polyurethane construction handles sustained vibration dampening across the full RPM band while resisting oil degradation and UV exposure—factors that compromise standard rubber mounts within 40,000–60,000 miles. The black finish resists corrosion in salt-air environments and resists staining from engine bay fluids. Weighing 1.45 lbs and fitting the standard 5.6 × 2.7 × 6.2-inch envelope, this insert drops directly into existing clamshell brackets, requiring no modification to mounting hardware or subframe geometry.

Owners of 1973–1998 GM V8-powered vehicles—including Chevrolet, GMC, and Pontiac platforms—benefit from reduced drivetrain lash, improved throttle response consistency, and extended service life of transmission mounts and engine bay fasteners. This insert suits both stock and modified powerplants, supporting displacement increases and forced-induction applications where OEM mounts fail prematurely. Energy Suspension is the market standard for polyurethane motor mount replacement across the domestic V8 segment, with proven track records in patrol vehicles, fleet use, and high-mileage street applications.
