Designed for supported 1992–1995 Honda Civic, 1993–1997 Honda del Sol, and 1994–2001 Acura Integra applications, the Innovative Mounts 40156 replaces worn factory engine mounts with durable steel mounting components and performance polyurethane bushings.

Unlike automatic-to-manual conversion mount kits, the 40156 is specifically designed to retain the factory automatic hydraulic transmission configuration.

Featuring Innovative Mounts' no-tear polyurethane bushings, CAD/CAM-engineered construction, and stress-analyzed design, this replacement mounting system helps reduce excessive engine movement, improve drivetrain stability, and deliver more consistent powertrain positioning during acceleration and shifting.

Whether you're replacing deteriorated factory mounts, restoring a daily-driven Integra, or upgrading a modified B-Series or D-Series automatic Honda, the Innovative Mounts 40156 provides a dependable performance-oriented mounting solution.

Designed for Factory Automatic Transmission Applications

The Innovative Mounts 40156 is engineered for Honda and Acura chassis using compatible B-Series or D-Series engines with automatic hydraulic transmissions.

Unlike manual conversion kits, this system retains the original automatic transmission mounting arrangement while replacing the factory rubber mounting components with performance polyurethane bushings.

Key benefits include:

• Direct replacement design for supported automatic transmission applications.

• Compatibility with supported Honda B-Series and D-Series engines.

• Designed for a 2-bolt driver-side engine post mount.

• Durable steel mounting construction.

• Performance polyurethane bushings.

• Reduced excessive engine and transmission movement.

• Improved drivetrain stability during acceleration.

• More consistent engine positioning.

• Bolt-on installation using factory OEM hardware.

• Multiple bushing hardness options.

Performance Polyurethane Bushings

Factory engine mounts use rubber and, in certain positions, fluid-filled damping components to isolate engine vibration from the chassis.

Over time, these mounts can deteriorate, crack, leak, or lose their ability to properly support the drivetrain.

Innovative Mounts replaces the factory-style damping arrangement with its performance-oriented no-tear polyurethane bushing design.

Polyurethane bushings provide increased resistance to engine movement, helping maintain drivetrain alignment during acceleration, deceleration, and transmission engagement.

Benefits include:

• Reduced engine rocking.

• Improved throttle response.

• Reduced excessive drivetrain movement.

• More consistent engine and transmission positioning.

• Potential reduction in wheel hop.

• Improved durability for performance applications.

• Multiple stiffness options to suit different driving requirements.

Durable Steel Construction

The Innovative Mounts 40156 uses steel mounting components engineered for strength and long-term drivetrain support.

Each mounting component is developed using CAD/CAM engineering and stress analysis to help provide consistent fitment and dependable performance.

The kit is designed to position the drivetrain correctly without introducing axle bind when installed in a supported application.

Required 2-Bolt Driver-Side Post Mount

The Innovative Mounts 40156 requires a 2-bolt driver-side engine post mount, located on the timing belt side of the engine.

This is an essential fitment requirement.

Applications using a 3-bolt driver-side engine post mount require a different mounting configuration.

For supported applications requiring a replacement 2-bolt engine-side post mount, Innovative Mounts offers:
