Frequently Asked Questions

What is the MR1-HDG6?

It is the ACT single-disc clutch kit described in this listing for the stated application and use.

How do I confirm fitment?

Match the complete year, make, model, engine, transmission and every qualifier shown in the title and fitment section.

Is this intended for street use?

This listing contains a race-oriented or not-for-street-use designation. Follow ACTs stated use and drivability guidance.

Can I mix clutch components from different kits?

Do not assume components are interchangeable. Verify spline, diameter, step height, release system and the complete matched ACT assembly.

Does installation require break-in?

Follow the current ACT instructions for the exact clutch and disc type. Street friction systems commonly require a controlled break-in period; race products can differ.

Should the flywheel be inspected or resurfaced?

Yes. Inspect the mating surface and use only a compatible flywheel prepared to ACT specifications. Replace damaged or out-of-spec components.

Is professional installation recommended?

Yes. Clutch and flywheel work requires correct transmission removal, fastener torque, alignment, release-system setup and safety procedures.

Can Black Ops Auto Works help verify the application?

Yes. Provide the vehicle, engine, transmission, existing flywheel, power level and intended street or competition use before ordering.

Installation Instructions

1. Confirm ACT part and the complete engine, transmission, flywheel, spline, and release-system application before disassembly.
2. Inspect every component and compare the new part with the removed assembly before modifying or installing anything.
3. Inspect the flywheel or friction surface, pilot support, release bearing, fork, pivot, hydraulic system, seals, and mounting hardware.
4. Clean friction surfaces correctly and keep oil, grease, and fingerprints away from the clutch disc and mating faces.
