Description
The factory manual clutch in the BA and BF Falcon XR6 Turbo was never built to cope with the immense torque a modified 4.0L Barra engine can generate. If your clutch is slipping under acceleration or you are planning an upgrade path for more grunt, the Xtreme Performance HD Clutch Kit is the ultimate street friendly solution. This comprehensive Stage 1 266mm heavy duty kit features a premium sprung organic friction disc combined with an upgraded high clamp pressure plate, delivering a massive 25% increase in clamping force and a robust 630 Nm torque capacity while preserving smooth engagement and comfortable pedal effort for everyday driving.
Unlike harsh ceramic button options that chatter and bite aggressively in heavy traffic, the high performance sprung organic design dampens drivetrain vibrations and provides excellent modulation, making it perfect for daily driven street cars, weekend cruisers, and spirited highway driving. This 600 Series kit comes complete with a single mass replacement flywheel, ensuring a perfectly matched, fresh friction surface from day one. Say goodbye to clutch slip and confidently transfer every bit of your Barra engine power straight to the rear wheels.

Frequently Asked Questions
Will a heavy-duty Xtreme clutch make my pedal too stiff for daily traffic?
Not at all. Because this kit utilises a quality engineered diaphragm in the pressure plate and premium organic friction materials, the pedal feel remains remarkably close to the stock setup. It offers a clear, predictable bite point without the heavy, leg straining pedal effort often associated with extreme track-focused clutches.
Does this kit suit both the 5-speed and 6-speed manual transmissions?
No, this specific kit is strictly engineered to suit the 6-speed manual transmission (Tremec T56) found in the BA MKII and BF Falcon XR6 Turbo models. The input shaft spline count and flywheel dimensions differ from the earlier 5-speed gearboxes, so verifying your transmission type before ordering is essential.
Is it important to include a replacement flywheel with an Xtreme clutch kit?
When a clutch wears out or slips, it generates intense heat which can cause hot spots, glazing, and surface cracks on the old flywheel face. Installing a brand new single-mass flywheel guarantees a perfectly flat, clean surface for the new organic disc to bed into, preventing an annoying clutch shudder and ensuring maximum torque transfer, not to mention extending the lifespan of the entire assembly.
