Product Details

This SPEC Stage 2 Clutch Kit for your 2004-2006 BMW 545i or 645i with the 4.4L engine includes the pressure plate, a high-performance clutch disc, and a new release bearing. This kit is designed to handle more power than the stock clutch, making it a solid choice if you've added modifications or simply want a more robust setup for spirited driving.

The Stage 2 clutch disc features a sprung hub design, which helps absorb drivetrain shock and provides a smoother engagement compared to unsprung discs, especially important when dealing with increased torque. The pressure plate is built to offer a firmer pedal feel and a stronger clamping force, ensuring the clutch can reliably transfer power without slipping under load. This combination is well-suited for vehicles that see regular street use but are also driven hard, or for those with mild performance upgrades.

When installing this clutch kit, it's important to have the flywheel resurfaced or replaced to ensure proper contact with the new clutch disc. Always refer to the manufacturer's installation instructions for specific torque specifications and procedures. This kit is a direct replacement for the factory clutch components, simplifying the installation process.
