Spec 85-88 BMW 535 3.5L / 78-84 733 3.3L Stage 3 Clutch Kit

This SPEC Stage 3 clutch kit, part number SB153, is built with a sprung, multi-plate design, featuring a high-performance friction material that can handle significantly more torque than the factory setup. This makes it a solid choice for your 1978-1984 BMW 733i or your 1985-1988 BMW 535i and 535is, especially if you've modified your engine or plan on more aggressive driving. The sprung hub design helps to absorb some of the shock and vibration that can come with a higher-engagement clutch, offering a more comfortable experience than a solid hub would.

The Stage 3 designation means this kit is engineered for applications that demand more holding power. The multi-plate configuration increases the surface area for engagement, allowing it to transfer more power without slipping. This is crucial if you're pushing your BMW beyond its original specifications, whether through engine tuning or simply wanting a clutch that won't let you down during spirited driving sessions. SPEC has a well-known reputation for producing robust drivetrain components, and this clutch kit is no exception, offering a well-built solution for increased performance demands.

When installing this clutch kit, remember that it's designed to work with your vehicle's existing flywheel, though it's always a good idea to inspect your flywheel for wear or damage during the clutch replacement process. This kit includes the clutch disc and pressure plate, providing the core components needed for a clutch upgrade. Ensure you follow the manufacturer's installation instructions carefully for proper engagement and break-in procedures to get the most out of this performance clutch.
