Overview

High-performance lightweight single mass flywheel designed for Alfa Romeo and Lancia vehicles equipped with the 1750 TBi turbocharged engine. Engineered to replace the heavy OEM dual-mass flywheel, providing sharper engine response and handles increased torque with ease.

Specifications

• Weight: 5.2 kg
• OEM dual-mass flywheel: ~11.5 kg
• Type: Single mass conversion, billet steel
• Balancing tolerance: ≤ 0.1 g
• Individually balanced (not batch processed)

Performance Characteristics

Replacing the heavy dual-mass flywheel results in:

• elimination of OEM dual-mass failure points under high torque
• sharper turbo spool-up and crisper throttle response
• more direct drivetrain connection and enhanced driver feedback
• Ideal for tuned street cars, track cars, and stage-optimized setups.

Construction

• Precision CNC machined from solid steel billet for superior strength
• Engineered to withstand increased torque from tuned turbocharged engines
• Integrated high-durability ring gear
• Individually dynamically balanced to extreme racing tolerances

Compatibility

• Engine: 1750 TBi / 1.75 Turbo Benzina
• Models: Alfa Romeo Giulietta QV, 159, Brera, Lancia Delta III.
• Compatible with upgraded performance clutch kits designed for single mass conversion.

Included

• Lightweight billet steel conversion flywheel
• Individual balancing certificate (≤ 0.1 g)

Important

• Converting from a dual-mass to a single-mass flywheel increases mechanical drivetrain feedback and may result in noticeable gearbox noise (chatter) at idle.
• Recommended for enthusiasts and performance-tuned vehicles.
