Manufacturer Part Number: RB105
The exact ACT release bearing and quantity identified by the product title and MPN. Bearings, alignment tools, flywheel bolts, pressure-plate bolts, hydraulic parts, and related hardware are included only when specifically stated.
ACT develops application-specific clutch kits, friction discs, pressure plates, flywheels, bearings, and supporting drivetrain components for street and motorsport use. Black Ops Auto Works organizes every ACT listing by exact MPN and verified vehicle application.
The RB105 should be selected as part of a complete matched ACT drivetrain system.
What is the RB105?
It is the ACT release bearing 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.
