XClutch Stage 1 Organic Clutch & Flywheel (6-Bolt) – BMW 135i / 335i (N54)

OVERVIEW

XClutch sprung organic kits offer excellent dampening and the highest levels of driveability in the XClutch range, which makes them the natural choice for a performance street car that still has to behave in traffic.

This Stage 1 kit is a complete single-disc clutch and flywheel package for the 6-bolt crankshaft N54, rated by XClutch for up to 440 ft-lb of torque with a 70 percent increase in clamping force over stock. Everything needed for the job is in the box, including the flywheel, release bearing, pilot bushing and alignment tool.

TECH RESOURCES

Additional Parts Required

• None. XClutch supplies the flywheel, release bearing, pilot bushing, bolts, alignment tool and spline grease in the kit — no separate flywheel or bearing purchase is needed.
• Break-in is required. XClutch specifies driving the vehicle gently for the first 1,000 km (roughly 620 miles), avoiding aggressive launches; low-rpm engagements bed the friction material in properly.
• XClutch recommends inspecting the concentric slave cylinder while the transmission is out and replacing it if worn, since the labor is already committed.
• Professional installation; transmission removal is required.
