ACT 1987 Mazda RX-7 XACT Flywheel Prolite | 600140
This product is a Prolite flywheel, which is ACT's lighter flywheel offering with lowest inertia. Prolite flywheels are designed for best throttle response and acceleration. Prolite flywheels are preferred for road racing or rally racing, and have reduced drivability. Materials are properly distributed for maximum strength, good heat tolerance and rigidity. ACT flywheels are serviceable and can be resurfaced with no need to purchase.
Use ACT manufacturer part number 600140 to confirm the exact drivetrain component and application.

Frequently Asked Questions
What is the 600140?
It is the ACT flywheel 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?
Use suitability depends on the specific disc, pressure plate, flywheel and clutch configuration shown in the listing.
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
- Confirm ACT part and the complete engine, transmission, flywheel, spline, and release-system application before disassembly.
- Inspect every component and compare the new part with the removed assembly before modifying or installing anything.
- Inspect the flywheel or friction surface, pilot support, release bearing, fork, pivot, hydraulic system, seals, and mounting hardware.
- Clean friction surfaces correctly and keep oil, grease, and fingerprints away from the clutch disc and mating faces.
- Use the vehicle service procedure and current ACT instructions for alignment, fasteners, torque sequence, release travel, and clearances.
- Verify smooth release, correct free play, clean gear engagement, and leak-free operation before road use.
- Complete the manufacturer-specified break-in procedure before launches, dyno pulls, racing, towing, or full-torque operation.
