Exedy HCK1008 OEM Replacement Clutch Kit 2003-2007 Honda Civic Hybrid

Vehicle Fitment

• 2003-2005 Honda Civic Hybrid (L4 1.3L, LDA1, Gas/Electric SOHC, IMA Hybrid)
• 2006-2007 Honda Civic Hybrid (L4 1.3L, LDA2, Gas/Electric SOHC, IMA Hybrid)

Fitment Notes

• This kit fits the seventh-generation Honda Civic Hybrid (2003-2005, LDA1) and eighth-generation Civic Hybrid (2006-2007, LDA2) only. It does not fit any non-Hybrid Civic, the Civic Si, or any Civic with automatic transmission.
• The Honda Civic Hybrid uses Honda's Integrated Motor Assist (IMA) system, in which the electric motor is mounted directly between the combustion engine and the manual transmission. This means the clutch disc and pressure plate interface with the IMA motor flywheel assembly - professional installation by a technician familiar with Hybrid IMA drivetrain systems is strongly recommended.
• This kit is sold as a complete unit only - individual components are not available separately under this part number.
• Flywheel must be inspected and resurfaced or replaced per Exedy's specifications before installation. Exedy's 12-month/20,000-mile warranty is void if the flywheel has not been properly serviced.
• Does not fit 2008 or later Honda Civic Hybrid models, which use different IMA system configurations and different clutch part numbers.

Features

• OEM-specification replacement clutch kit engineered to Honda Civic Hybrid factory standards - manufactured on the same Exedy production lines used to supply Honda's OEM clutch components, restoring original clutch feel, engagement character, and service life to the 2003-2007 Civic Hybrid platform.
• Exedy is a Tier 1 OEM supplier to all 11 Japanese vehicle manufacturers including Honda, meaning the clutch components in this kit meet the exact engineering and quality specifications Honda requires of its original equipment supplier for the LDA1 and LDA2 Hybrid applications.
• All clutch cover assemblies undergo a precise robotic testing process for clamp load and clutch lift separation before leaving the production line, ensuring consistent pedal feel and engagement characteristics across every unit produced.
• Diaphragm spring is heat-treated to reduce contact surface wear and extend release bearing service life compared to untreated alternatives.
• WAD (Wide Angle Damper) disc design enables the clutch disc to hold torque with less clamping force than conventional designs - specifically relevant to the Civic Hybrid's IMA-assisted drivetrain, where the electric motor contributes to torque transfer alongside the combustion engine.
• Asbestos-free friction facing provides reliable heat resistance and burst strength appropriate to the 1.3L SOHC engine's operating range in both combustion-only and combined IMA-assist modes.

Product Description

The Exedy HCK1008 is an OEM replacement clutch kit for the 2003-2007 Honda Civic Hybrid, covering both the seventh-generation LDA1 (2003-2005) and eighth-generation LDA2 (2006-2007) powertrain configurations. As a Tier 1 OEM supplier to Honda, Exedy manufactures this kit to the exact same engineering specification as the original factory clutch - the components in this kit are produced on the same production lines as Honda-branded OEM clutch assemblies, making this a direct factory-equivalent replacement rather than an aftermarket approximation.

The Civic Hybrid's clutch application is functionally distinct from a conventional internal-combustion-only manual transmission setup. Honda's Integrated Motor Assist (IMA) system places the electric motor between the 1.3L combustion engine and the manual transmission, and the clutch friction disc and pressure plate interface directly with the IMA motor's flywheel assembly. The WAD (Wide Angle Damper) disc design is particularly suited to this application - it allows the clutch to manage torque contributions from both the combustion engine and the IMA motor without requiring disproportionate clamping force, which helps maintain the light, natural pedal feel Honda engineered into the Civic Hybrid's manual transmission option. The diaphragm spring is heat-treated to minimize wear at the release bearing contact point, extending system service life in line with Honda's original design intent.

This kit is sold as a complete unit and fits 2003-2007 Honda Civic Hybrid models only - it does not fit the standard Civic, the Civic Si, or any Civic with an automatic or CVT transmission. It does not fit 2008 and later Civic Hybrid models. Professional installation by a technician with experience on Honda IMA hybrid drivetrains is strongly recommended, as the IMA motor/flywheel assembly requires specific handling procedures during clutch replacement that differ from a conventional clutch job. The IMA flywheel should be inspected and serviced per Honda's specifications before the new clutch is installed.
