Sachs DMF91179 Dual Mass Flywheel Stock Replacement

The Sachs DMF91179 is a stock replacement dual mass flywheel (DMF) engineered for passenger car and light commercial vehicle applications. Manufactured by Sachs — a ZF brand and globally recognized OE supplier — this flywheel delivers factory-level fit, function, and durability.

A dual mass flywheel transmits engine torque to the clutch pressure plate and clutch disc while absorbing torsional irregularities before they reach the drivetrain. Modern engines produce increasing rotational vibration due to higher torque output, elevated ignition pressures, and tightened emissions requirements. The Sachs DMF91179 addresses these demands with a precision-engineered compression spring assembly and rpm-adaptive damping that effectively decouples torsional vibration from the powertrain.

Key Features:

• OE-quality stock replacement dual mass flywheel
• Steel construction for long-term strength and thermal resistance
• Reduces driveline noise, vibration, and harshness (NVH)
• Provides smoother gear shifts and improved clutch engagement
• Non-resurfaceable design — direct replacement when worn
• Sold individually
• UPC: 708609337557

Dual mass flywheels cannot be resurfaced like single mass units and must be replaced when worn. Common symptoms of a failing flywheel include clutch slipping, chattering, or sticking. The Sachs DMF91179 restores OE drivability and protects the transmission from harmful vibration.
