Motor Mounts

What Are Motor Mounts and Why Do They Matter?

Motor mounts — also called engine mounts — are the critical connection points between your engine and the vehicle's chassis. Their job is twofold: physically secure the engine so it can't shift or move under load, and absorb the vibration and noise the engine generates so it doesn't travel into the cabin or drivetrain. Motor mounts are among the hardest-working components in your engine bay, quietly enduring torque forces, heat cycles, road shock, and exposure to oil, coolant, and road grime every single mile.

Over time, the rubber or polyurethane bushing material inside a motor mount degrades, cracks, or collapses. A failed motor mount allows the engine to shift excessively during acceleration or braking — a symptom drivers often notice as a clunking noise, increased vibration through the floor or steering wheel, or a subtle but noticeable delay in throttle response. Left unaddressed, a bad motor mount can stress surrounding hoses, belts, and exhaust components, turning a relatively simple repair into a much more expensive one.

OEM Replacement vs. Performance Motor Mounts

When shopping for a replacement motor mount, you'll generally encounter two philosophies: OEM-style rubber mounts that prioritize ride comfort and NVH (noise, vibration, harshness) isolation, and stiffer polyurethane or billet performance mounts that prioritize drivetrain rigidity and response. The right choice depends on how you use your vehicle — daily commuter versus weekend track car — and your tolerance for cabin vibration.

• Rubber mounts closely replicate the factory feel and are ideal for stock or mildly modified daily drivers.
• Polyurethane mounts offer a middle ground — firmer than rubber for better drivetrain feedback, but not as harsh as solid metal racing mounts.
• Solid/billet mounts eliminate all flex for maximum power transfer, typically reserved for dedicated race applications.
• Hydraulic mounts use fluid-filled chambers to provide superior vibration damping, commonly found as OEM-spec components on many front-wheel-drive vehicles.

Top Motor Mount Brands

Innovative Mounts is a leading manufacturer of motor mounts, traction bars, shift linkages, and engine swap parts, with all products designed, cut, welded, and finished by their east coast team — ensuring strict quality control throughout production. Their mount kits are available in multiple durometer ratings (60A, 75A, 85A, 95A, and solid billet) to match everything from a street-driven Civic to a full competition build.

Anchor Industries has been a cornerstone of the motor mount market since 1933, earning recognition as one of the automotive aftermarket's most established suppliers of engine and transmission mounts. With an enormous catalog spanning domestic and import applications, Anchor designs all mounts to meet or exceed OEM specifications using CAD/CAM technology, making them a trusted choice for professional technicians and DIYers restoring or maintaining everything from vintage classics to modern daily drivers.

Energy Suspension brings a performance-oriented approach to motor mounts with their proprietary Hyper-Flex® polyurethane material. Their mounts sit between OEM rubber and rigid metal racing hardware — firmer than stock for improved throttle response and drivetrain stability, while still absorbing enough vibration for street use. Energy Suspension's polyurethane is also notably resistant to oil, coolant, road salt, and grime that accelerate rubber degradation.

DEA Products rounds out the OEM-replacement segment with a broad selection of engine and transmission mounts engineered for precise fit on a wide range of domestic and import vehicles. DEA is a practical choice for technicians and vehicle owners focused on restoring OEM-equivalent performance and noise isolation without an upcharge for performance features.
