Clutch Masters FW-401-SF Lightweight Steel Flywheel

The Clutch Masters FW-401-SF is a precision-engineered lightweight steel flywheel designed to replace heavy factory dual mass flywheels with a high-performance single mass design. Machined from 1045 or 4140 billet steel sourced from US manufacturers, this flywheel delivers significant weight reduction for improved throttle response and acceleration without sacrificing durability.

Key Features:

• Precision machined on CNC machines to exact tolerances for perfect fitment
• Black oxide coating ensures rust-free protection for the life of the flywheel
• SFI certified for use in all sanctioned racing bodies
• Reduces turbo lag in turbocharged engines
• Increased supercharger efficiency due to less drag on the crank
• Compatible with OEM clutch kits or aftermarket clutches built to OEM specifications
• Designed and manufactured in the USA

Performance Benefits:

• Lightweight design for improved performance and quicker revs
• Improved mid-range torque in naturally aspirated engines
• Replaces factory performance-robbing dual mass flywheel
• Can be resurfaced for extended service life unlike dual mass flywheels
• Zero balanced to ensure even weight distribution and 100% true spinning

Every Clutch Masters steel flywheel undergoes rigorous quality control throughout the manufacturing process, with craftsmen continuously checking critical measurements to ensure specifications are met. After coating, flywheels are laser engraved with the Clutch Masters logo and part number for authenticity and traceability.
