Competition Clutch 2-617-7STU Ultra Lightweight Steel Flywheel

The Competition Clutch Ultra Lightweight Steel Flywheel (STU suffix) is recommended for forced induction and/or track and rally racing applications. This flywheel is machined with less material to assist in quicker revving capabilities, making it ideal for performance-focused builds where throttle response and rev-matching are critical.

Key Features:

• Made of 4140 forged steel and are a one-piece design
• Helps significantly in reducing the chances of ring gear separation and friction surface warpage
• Well-suited for Stage 3 and up clutch applications
• All flywheels can be resurfaced
• All flywheels are SFI certified
• These flywheels will work with ALL performance and stock clutch assemblies

The ultra lightweight design significantly reduces drivetrain inertia, allowing your engine to rev up more quickly on throttle and lose revs faster when you lift off. This enhanced response is particularly beneficial for turbocharged engines, track driving, and rally racing where rapid gear changes and precise rev-matching are essential. The one-piece forged steel construction ensures maximum durability and heat resistance even under extreme racing conditions.
