Engineered to improve drivetrain stability, reduce excessive engine movement, and provide increased durability compared with aging factory rubber and hydraulic engine mounts, this performance-oriented mounting kit is an excellent upgrade for daily-driven Accords, modified street cars, and high-performance builds.

The factory engine mounting system is designed to isolate vibration and maintain passenger comfort. However, as original rubber and hydraulic mounts age, they can crack, deteriorate, or leak, allowing excessive engine and transmission movement during acceleration, deceleration, and gear changes.

Excessive drivetrain movement can contribute to inconsistent throttle response, unwanted engine rocking, wheel hop, and additional stress on surrounding components. These problems may become more noticeable in modified vehicles producing increased horsepower and torque.

Innovative Mounts addresses these concerns with heavy-duty steel mounting assemblies and specially engineered polyurethane bushings. Unlike conventional fluid-filled hydraulic mounts, the polyurethane design provides increased resistance to drivetrain movement while maintaining vibration isolation appropriate to the selected bushing hardness.

The Innovative Mounts 20251 includes three primary mounting assemblies and a driver-side mounting bracket. Together, these components provide a coordinated mounting solution for compatible automatic-transmission Accord applications.

Each mount features Innovative Mounts' unique no-tear polyurethane bushing design, engineered to control excessive drivetrain movement while minimizing unnecessary binding. This construction helps maintain more consistent engine positioning under load and can improve overall drivetrain response.

The kit is CAD/CAM designed, stress analyzed, and engineered for bolt-on installation using compatible factory mounting locations and original Honda mounting hardware.

Important: Installation requires the appropriate F-Series timing belt-side engine post mount, Honda part number 11910-P0A-010, used in specified 1995–1998 Honda Odyssey and 1994–2002 Honda Accord applications.

The Innovative Mounts 20251 also supports compatible 1998-and-newer H-Series engine configurations using the specified mounting arrangement. For earlier H-Series engines requiring the Prelude-style timing belt-side mounting post, Innovative Mounts offers the alternative 20253 automatic-transmission conversion kit.

Available in 75A, 85A, and 95A polyurethane bushing hardness options, this kit allows enthusiasts to select the appropriate level of drivetrain rigidity for their intended use.

Whether you're replacing worn factory mounts on your Accord, upgrading a naturally aspirated F23 engine, or completing a compatible automatic H-Series conversion, the Innovative Mounts 20251 provides a durable foundation for improved drivetrain stability and performance.
