The BLOX Racing EDEL 7.25" Twin Disc Clutch Kit (BXFL-10225) is a high-performance racing clutch and lightweight flywheel system engineered for Honda D-Series engines producing substantially more horsepower and torque than factory drivetrain components can handle.

Developed by EDEL for BLOX Racing, this competition-oriented clutch system combines a compact 7.25-inch (185mm) twin disc design, dual cerametallic friction discs, a vented aircraft-quality aluminum pressure plate cover, and a lightweight one-piece billet chromoly flywheel. The result is a purpose-built drivetrain upgrade designed to provide exceptional holding capacity, efficient power transfer, and responsive clutch operation under demanding performance conditions.

Rated to support applications producing up to 1100 horsepower and 700 lb-ft of torque, the BLOX Racing EDEL Twin Disc Clutch is designed for heavily modified naturally aspirated and turbocharged Honda D-Series engines. Its dual-disc configuration increases the available friction surface area compared to conventional single-disc clutch assemblies, allowing the system to manage substantially higher torque loads.

The compact 185mm clutch assembly features a low moment of inertia, helping reduce rotating mass and improve engine responsiveness during rapid acceleration, deceleration, and high-RPM shifting. Combined with the included billet chromoly flywheel, this design supports quicker engine speed changes and improved drivetrain response during competitive driving.

The pressure plate assembly features an aircraft-quality aluminum alloy cover with a vented design engineered to assist with heat management. Each pressure plate is load-tested for quality assurance, while the solid-center cerametallic friction discs provide direct engagement and reliable power transfer during aggressive launches and high-load operation.

Supplied with a lightweight flywheel, throw-out bearing, and clutch alignment tool, the BLOX Racing BXFL-10225 offers a comprehensive clutch upgrade for compatible Honda D-Series manual transmission applications.

Whether building a high-boost D16, preparing a dedicated drag racing Civic, or upgrading a high-horsepower D-Series race engine, the BLOX Racing EDEL Twin Disc Clutch Kit delivers the holding capacity, durability, and motorsport-focused engineering required for serious performance applications.

Important Fitment Information:

BLOX Racing officially lists this clutch kit for Honda D-Series applications but does not provide a complete model-year and transmission-specific fitment chart. Compatibility must be verified against the crankshaft, flywheel mounting configuration, transmission input shaft, and clutch release system before ordering.

Performance Capacity Note:

The advertised 1100 HP and 700 lb-ft ratings represent manufacturer-stated maximum capacities. Actual clutch performance depends on engine torque characteristics, vehicle weight, launch conditions, installation quality, and operating temperatures.

Important: Although some distributor listings describe this clutch as a sprung configuration, BLOX Racing's technical specifications identify solid-center friction discs. Customers should expect aggressive engagement and increased drivetrain noise, chatter, and vibration compared to a conventional sprung-hub street clutch.

3. Remove the Factory Clutch Assembly: Follow the applicable Honda service procedures when removing the transmission, clutch, and flywheel.

4. Inspect the Crankshaft Flange: Ensure the crankshaft mounting surface is clean, undamaged, and free of debris.

5. Install the Supplied Flywheel: Mount the one-piece billet chromoly flywheel using the correct hardware and manufacturer-specified torque procedure.

6. Inspect the Twin Disc Components: Verify the condition and orientation of both friction discs, the center floater, and the pressure plate assembly.

7. Follow the Correct Installation Sequence: Install the friction discs and center floater in the exact order specified by BLOX Racing or EDEL.

8. Use the Supplied Alignment Tool: Ensure both clutch discs are correctly aligned with the transmission input shaft.

9. Install the Pressure Plate Assembly: Tighten the mounting hardware evenly according to the manufacturer's specified sequence and torque values.

10. Verify Release Bearing Compatibility: Confirm that the throw-out bearing and release mechanism provide the required operating geometry.

11. Check Clutch Release Travel: Verify that the release system provides the specified 5mm travel without overextending the clutch assembly.

12. Reinstall the Transmission: Carefully align the transmission input shaft with both clutch discs without forcing the transmission into position.

13. Inspect Clutch Operation: Verify proper engagement and disengagement before operating the vehicle under load.

14. Check for Interference: Confirm adequate clearance between the clutch assembly, transmission bellhousing, and surrounding components.

15. Follow Manufacturer Break-In Instructions: Complete the break-in procedure specified by BLOX Racing or EDEL before aggressive driving.
