034Motorsport Single Mass Flywheel for B7 Audi RS4 | 034-503-1018

The 034Motorsport Single Mass Flywheel (034-503-1018) is a premium drivetrain upgrade for the B7 Audi RS4. Designed to replace the cumbersome and failure-prone factory dual-mass unit, this flywheel is precision-machined in-house from high-strength 6061 billet aluminum. Weighing in at just 13 lbs—a reduction of 13.5 lbs compared to the 26.5 lb OEM flywheel—it dramatically lowers rotational inertia, allowing the high-revving 4.2L FSI V8 to reach its 8,250 RPM redline with even greater urgency.

By significantly improving throttle response and simplifying rev-matching during downshifts, this lightweight flywheel enhances the visceral driving experience the RS4 is known for. It features a replaceable steel friction surface, ensuring that the main aluminum body can be reused during future clutch services, and comes complete with new high-strength flywheel bolts for a secure, worry-free installation.

Key Features:

• Significant Weight Reduction: At 13 lbs, it is over 50% lighter than the stock flywheel, offering a massive increase in engine response.
• 6061 Billet Aluminum Construction: Machined for superior strength-to-weight ratio and durability under high-RPM conditions.
• Improved Drivability: Reduces the delay in RPM drop between shifts and makes heel-toe downshifting much more precise.
• Replaceable Friction Surface: Includes a high-grade steel friction plate that is easily replaceable, prolonging the life of the flywheel.
• Direct Replacement: Engineered specifically for the B7 RS4 to replace the factory dual-mass flywheel (DMF) without complex modifications.
• Complete Hardware Kit: Includes fresh flywheel bolts to ensure a proper and safe installation.

Technical Specifications:

Driving Note: As with all lightweight single-mass flywheels, a slight increase in gear "chatter" or noise may be heard from the transmission at idle. This is a standard characteristic of performance drivetrain components and does not indicate a defect.
