Upgrade your Honda or Acura K-Series drivetrain with the Innovative Mounts Rear Engine Mount (10731), designed for 2003–2007 Honda Accord 2.4L and 2004–2008 Acura TSX applications equipped with K-Series engines and compatible manual or automatic transmissions.

Engineered to improve drivetrain stability, reduce excessive engine movement, and provide increased durability compared with aging factory rubber or hydraulic mounts, this performance rear engine mount is an excellent upgrade for daily-driven vehicles, modified street cars, and dedicated performance builds.

Factory Honda and Acura engine mounts are designed primarily to isolate engine vibration and provide a comfortable driving experience. Over time, original rubber and hydraulic mounting components can deteriorate, crack, leak, or separate, allowing excessive engine movement during acceleration, deceleration, and gear changes.

This unwanted movement becomes particularly noticeable in modified K-Series applications where increased horsepower and torque place additional stress on factory mounting components. Excessive drivetrain movement can contribute to wheel hop, inconsistent shifting feel, and unnecessary stress on surrounding components.

Innovative Mounts addresses these limitations with a performance-oriented rear mounting assembly featuring specially engineered polyurethane bushings. By reducing the compliance associated with factory-style mounts, the Innovative Mounts 10731 helps maintain more consistent engine and transmission positioning under load, improving drivetrain response and reducing unwanted movement during spirited driving.

Unlike traditional fluid-filled factory mounts, the Innovative Mounts 10731 utilizes a durable polyurethane bushing system designed to provide increased resistance to drivetrain movement while retaining vibration isolation appropriate to the selected bushing hardness.

Each mount is CAD/CAM designed and stress analyzed for strength, durability, and precise fitment. Available in multiple polyurethane bushing hardness options, the Innovative Mounts 10731 allows enthusiasts to select the appropriate balance between everyday driving comfort and performance-oriented drivetrain rigidity.

Whether you're replacing a worn rear engine mount on your Honda Accord K24, improving drivetrain stability in your Acura TSX, or preparing your K-Series engine for additional horsepower, the Innovative Mounts 10731 provides the strength and durability needed for demanding applications.

Installation Notes

1. Verify Vehicle Compatibility: Confirm that the vehicle is a compatible 2003–2007 Honda Accord 2.4L or 2004–2008 Acura TSX equipped with a supported K-Series engine.

2. Confirm Mounting Position: Innovative Mounts 10731 replaces the rear engine mount. It is not intended for front or passenger-side mounting positions.

3. Verify OEM Mount Compatibility: Confirm that the original mounting configuration corresponds to the manufacturer's specified OEM references.

4. Support the Engine and Transmission: Properly support the drivetrain before removing the factory rear engine mount to prevent unexpected movement or damage.

5. Remove the Factory Rear Engine Mount: Follow the appropriate Honda or Acura service procedures when removing the original mounting assembly.

6. Inspect Factory Mounting Locations: Check the chassis mounting points, engine brackets, transmission brackets, and surrounding components for damage or excessive wear.

7. Install the Innovative Mounts Assembly: Position the replacement rear engine mount according to the manufacturer's instructions, ensuring correct orientation and alignment.

8. Inspect Factory Hardware: Examine original mounting bolts and fasteners before reuse. Replace damaged or excessively worn hardware.

9. Align the Drivetrain: Ensure the engine and transmission are properly positioned before final tightening to prevent unnecessary bushing preload.

10. Torque Mounting Hardware: Tighten all fasteners according to the applicable Honda/Acura and Innovative Mounts specifications.

11. Verify Component Clearance: Check clearance around the engine, transmission, exhaust system, steering components, and surrounding chassis structure before operating the vehicle.

12. Select the Appropriate Bushing Hardness: Choose the polyurethane durometer that best matches the vehicle's horsepower level, intended use, and acceptable vibration.

13. Expect Increased Engine Vibration: Performance polyurethane mounts generally transmit more engine vibration into the chassis than factory rubber or hydraulic mounts. Higher-durometer bushings typically increase vibration further.
