034Motorsport Lightweight Single Mass Flywheel for B7 Audi A4 | 034-503-1020

The 034Motorsport Lightweight Single Mass Flywheel is a high-performance upgrade for the B7 Audi A4. Precision-machined in-house from 6061 billet aluminum, this flywheel is engineered to replace the heavy, failure-prone factory dual-mass unit. Weighing only 12 lbs—nearly 50% lighter than the 23 lb stock equivalent—it significantly reduces rotational inertia, allowing for faster engine revving, crisper throttle response, and effortless rev-matching during downshifts.

Specifically designed to utilize the B7 RS4 pressure plate and clutch disc, this flywheel allows A4 owners to benefit from the increased clamping force of the RS4’s factory components. This setup is the ideal solution for enthusiast drivers seeking a more connected driving experience and a more robust drivetrain capable of handling increased power levels.

Key Features:

• Reduced Rotational Mass: At 12 lbs, it is 11 lbs lighter than stock, drastically improving engine response and acceleration.
• Billet Aluminum Construction: Machined from 6061 billet aluminum for superior strength and weight reduction.
• RS4 Clutch Compatibility: Engineered to pair with the B7 RS4 pressure plate for significantly increased torque capacity.
• Long-Term Durability: Features a replaceable steel friction surface and a steel ring gear, ensuring the flywheel can be serviced rather than replaced.
• Direct Replacement: Eliminates the common failure points of the factory dual-mass flywheel (DMF).
• Hardware Included: Comes complete with a set of new, high-strength flywheel bolts for a secure installation.

Technical Specifications:

Driving Note: Transitioning from a dual-mass to a lightweight single-mass flywheel will result in more engine noise/chatter at idle and a faster drop in RPM between shifts. This is normal and expected for high-performance drivetrain components.
