The SPEC Stage 3+ clutch kit for select BMW six-cylinder models replaces the clutch assembly for heavy-duty street and track use. It is specified for 1984 BMW 533/633/733, 1985–1989 BMW 635 3.5L and 1985–1987 BMW 735 applications. The Stage 3+ label indicates a higher-capacity clutch option intended to handle upgraded drivetrains where a stronger clutch is required.
