Hardrace Harden Engine Mount Set – Honda Civic FD (7385)

Product Overview

The 8th-generation Honda Civic chassis utilizes a transverse engine layout that subjects the factory motor mounts to significant rotational forces during acceleration and braking. Over time, the soft OEM rubber mounts tear, sag, and leak fluid, causing the engine to pitch excessively. This movement creates a delayed throttle response, vague shifter engagement, and traction-robbing wheel hop during hard launches.

The Hardrace Harden Engine Mount Set – Honda Civic FD (7385) is a 5-piece direct replacement upgrade designed to stabilize the powertrain. Available at JDMaster.net, this set utilizes structural steel housings filled with Hardrace’s proprietary high-durometer hardened rubber compound. By upgrading to these heavy-duty mounts, you restrict engine pitching under load, ensuring mechanical energy is delivered directly to the drivetrain rather than being absorbed by failing factory rubber.

Key Features & Benefits

• 5-Piece Complete Package: Replaces all primary engine and transmission torque mounts to secure the powertrain assembly completely.

• High-Durometer Hardened Rubber: Stiffer than factory rubber to limit engine movement without creating the harsh cabin vibrations associated with solid polyurethane or aluminum mounts.

• Improved Throttle Response: Minimizes engine deflection under acceleration, delivering more immediate torque transfer to the front wheels.

• Precise Shifter Engagement: Keeps the transmission casing properly aligned, reducing the risk of missed gears or binding gear linkages during hard shifting.

• Reduces Wheel Hop: Stabilizes the front axle geometry during hard launches to help maintain tire contact with the pavement.

• Bolt-On Installation: Precision-molded to original equipment specifications to fit directly into factory mounting points without modification.

Technical Specifications

Applications

This engine mount set is engineered to match the chassis layout and bracket configurations of the following models:

• Honda Civic / Civic Si Sedan 8th Gen (2006–2011 FD/FA Chassis excl. Type-R)

• Note: Please verify your specific subframe and mounting bracket style prior to purchase, as global chassis variations exist.

The Mechanical Advantage: Eliminating Powertrain Pitch

When you step on the accelerator in a front-wheel-drive car, the engine attempts to rotate in the opposite direction of the wheels. In the Civic FD chassis, this twisting force (torque reaction) is managed by the upper and lower torque mounts. Factory mounts contain large voids to isolate the cabin from engine harmonics, but this allows the engine to tilt back and forth by several inches under load.

Hardrace fills these voids with a solid, high-density rubber compound. When you apply power, the hardened rubber resists compression, stopping the engine from pitching. This stability protects the exhaust downpipe flex joints from cracking, prevents the shift cables from binding, and forces the tires to bite the tarmac immediately rather than waiting for the engine to settle.
