Upgrade your fourth-generation Honda Accord with the Innovative Mounts Steel Replacement Engine Mount Kit (29355), specifically designed for 1990–1993 Honda Accord DX and LX models equipped with an F-Series engine and factory-style 1990–1993 manual transmission.

Engineered as a performance-oriented replacement for worn factory engine mounts, this three-piece mounting kit provides increased drivetrain stability, reduced engine movement, and improved durability for street-driven and modified Honda Accord applications.

The fourth-generation Honda Accord remains a popular platform among enthusiasts thanks to its reliable F-Series engine, lightweight performance potential, and extensive aftermarket support. However, as factory engine mounts age, their rubber components can crack, deteriorate, or separate, allowing excessive engine and transmission movement.

Worn mounts can contribute to noticeable engine rocking, clunking during acceleration or deceleration, inconsistent shifting feel, and additional stress on surrounding drivetrain components.

The Innovative Mounts 29355 addresses these concerns with heavy-duty steel mounting assemblies and specially engineered polyurethane bushings.

Unlike conventional factory rubber or hydraulic mounts, polyurethane bushings provide increased resistance to drivetrain movement. This helps maintain more consistent engine and transmission positioning during acceleration, deceleration, and gear changes.

The kit features Innovative Mounts' unique no-tear polyurethane bushing design, developed to control unwanted engine movement while providing vibration isolation appropriate to the selected bushing hardness.

Each mounting assembly is CAD/CAM designed and stress analyzed for strength, durability, and accurate fitment.

The 29355 includes the driver-side engine mount, passenger-side transmission mount, and rear engine mount, providing a coordinated replacement solution for the three primary drivetrain mounting positions.

Important Transmission Compatibility

The Innovative Mounts 29355 is specifically engineered for 1990–1993 Honda Accord DX/LX applications using the original-style 1990–1993 F-Series manual transmission.

It is not intended for later 1994–2001 F-Series manual transmissions or H-Series transmission conversions.

For those applications, Innovative Mounts offers the 29350 conversion engine mount kit.

Important Rear Engine Mount Configuration

The 29355 uses the shorter, three-bolt rear engine mounting arrangement associated with compatible DX/LX chassis configurations.

Vehicles equipped with the taller four-bolt rear mounting arrangement, commonly found on factory manual Accord EX models, require a different mounting kit.

For compatible EX manual-transmission applications, see Innovative Mounts 29356.

Required Engine Mounting Post

Installation requires the 1990–1993 Honda Accord F-Series timing belt-side engine post, Honda part number 11910-PT0-010.

This component must be installed on the engine or sourced separately before installation.

Available with 75A, 85A, or 95A polyurethane bushings, the Innovative Mounts 29355 allows enthusiasts to choose the appropriate level of drivetrain rigidity for street performance, track use, or competition applications.

Whether you're restoring a CB7 Accord, replacing worn factory mounts, or upgrading your F22-powered street car, the Innovative Mounts 29355 provides a durable mounting solution designed for your Honda.

Installation Notes

1. Verify Vehicle Compatibility: Confirm that the vehicle is a supported 1990–1993 Honda Accord DX/LX CB7/CB9 chassis.

2. Confirm Engine Configuration: Verify that the vehicle uses a compatible F-Series engine.

3. Identify the Manual Transmission: Confirm that the installed transmission is a compatible 1990–1993 F-Series manual transmission.

4. Check Later Transmission Applications: If using a 1994–2001 F-Series or compatible H-Series manual transmission, evaluate Innovative Mounts 29350 instead.

5. Inspect the Rear Engine Mount Configuration: Verify that the vehicle uses the required short, three-bolt rear mounting arrangement.

6. Check Accord EX Applications: Vehicles using the taller four-bolt rear mount may require Innovative Mounts 29356.

7. Confirm Required Engine Post: Installation requires Honda part number 11910-PT0-010.

8. Support the Engine and Transmission: Properly support the drivetrain before removing the original mounting components.

9. Remove Existing Engine Mounts: Follow the appropriate Honda service procedures when removing the original mounting assemblies.

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

11. Install the Driver-Side Engine Mount: Position the Innovative Mounts 29310 assembly according to the manufacturer's instructions.

12. Install the Passenger-Side Transmission Mount: Position the Innovative Mounts 29323 assembly at the designated transmission mounting location.

13. Install the Rear Engine Mount: Position the Innovative Mounts 29630 assembly at the short three-bolt rear mounting location.

14. Reuse Compatible OEM Hardware: Inspect original Honda mounting hardware and replace any damaged or worn fasteners.

15. Align the Drivetrain: Ensure the engine and transmission are correctly positioned before final tightening.

16. Avoid Bushing Preload: Confirm proper drivetrain alignment to prevent unnecessary stress on the polyurethane bushings.

17. Torque Mounting Hardware: Tighten all fasteners according to Innovative Mounts' installation instructions and applicable Honda service specifications.
