Upgrade your fourth-generation Honda Civic or second-generation Honda CRX with the Innovative Mounts Steel D-Series Replacement Engine Mount Kit (19151), designed for 1988–1991 Honda Civic and CRX applications equipped with compatible D-Series engines and cable-operated manual transmissions.

Engineered to improve drivetrain stability, reduce excessive engine movement, and provide increased durability compared with aging factory rubber mounts, this three-piece performance replacement kit is an excellent upgrade for daily-driven vehicles, modified street cars, autocross builds, and dedicated racing applications.

Factory Honda engine mounts are designed to isolate engine vibration and maintain passenger comfort. Over time, the original rubber mounting components can deteriorate, crack, or separate, allowing excessive engine and transmission movement during acceleration, deceleration, and shifting.

Excessive drivetrain movement can contribute to wheel hop, inconsistent shifting feel, and unnecessary stress on surrounding components. These problems can become more noticeable in modified D-Series applications where increased horsepower, torque, and traction place additional demands on the factory mounting system.

Innovative Mounts addresses these concerns with heavy-duty steel mounting assemblies and specially engineered polyurethane bushings. The upgraded design helps maintain more consistent drivetrain positioning under load while reducing unwanted engine movement.

The Innovative Mounts 19151 includes three primary replacement mounting assemblies: a driver-side engine mount, passenger-side transmission mount, and rear engine mount. Replacing all three locations together provides a coordinated mounting solution for improved drivetrain stability.

Unlike conventional factory rubber mounts, Innovative Mounts' performance-oriented polyurethane bushings provide increased resistance to drivetrain deflection. The company's unique no-tear bushing design is engineered to minimize binding while progressively absorbing engine movement and vibration.

Each mount is CAD/CAM designed and stress analyzed for strength, durability, and precise fitment. The kit is designed as a direct bolt-in replacement for compatible factory mounting locations, utilizing the original Honda mounting hardware.

The Innovative Mounts 19151 maintains the intended factory engine position, helping preserve proper drivetrain alignment without axle binding. No trimming or notching of the factory hood is required for the supported original engine configuration.

Available in multiple polyurethane bushing hardness options, the kit allows enthusiasts to choose the appropriate balance between street-driving comfort and competition-oriented drivetrain rigidity.

Whether you're restoring a D15-powered Civic, upgrading your CRX Si, or improving engine stability in a turbocharged D16 performance build, the Innovative Mounts 19151 provides the strength, durability, and drivetrain control needed for demanding applications.

Installation Notes

1. Verify Vehicle Compatibility: Confirm that the vehicle is a compatible 1988–1991 Honda Civic or CRX.

2. Confirm Engine Configuration: Innovative Mounts 19151 is designed for compatible D-Series engines using the supported pre-1992 mounting arrangement.

3. Verify Transmission Type: Confirm that the vehicle uses a compatible D-Series cable-operated manual transmission.

4. Inspect the Driver-Side Engine Bracket: Later 1992-and-newer D-Series engines may require a different driver-side mounting solution.

5. Support the Engine and Transmission: Properly support the drivetrain before removing the original mounting components to prevent unexpected movement or damage.

6. Remove the Factory Engine Mounts: Follow the appropriate Honda service procedures when removing the original driver-side, passenger-side, and rear mounting assemblies.

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

8. Install the Driver-Side Engine Mount: Position the Innovative Mounts 19111 assembly in the corresponding factory mounting location.

9. Install the Passenger-Side Transmission Mount: Position the Innovative Mounts 19121 assembly according to the manufacturer's instructions.

10. Install the Rear Engine Mount: Position the Innovative Mounts 19131 assembly in the factory rear mounting location.

11. Reuse Compatible OEM Hardware: The kit is designed to utilize factory mounting hardware. Inspect all original bolts and fasteners before reuse.

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

13. Verify Axle Alignment: Confirm that the drivetrain is correctly positioned and that the axles operate without binding.

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