ACT 601510 XACT Streetlite Chromoly Steel Flywheel SFI 1.1

The ACT 601510 XACT Streetlite Flywheel is a high-performance, lightweight replacement flywheel engineered for enthusiasts who demand improved throttle response and acceleration. Considerably lighter than a stock flywheel, the Streetlite is ACT's most durable flywheel offering and is preferred for both street driving and drag racing applications.

Key Features:

• Forged Chromoly Steel Construction: Hot-forged chrome-moly steel provides extreme strength and long-term durability under hard use
• Lightweight Design: Significantly reduced rotational mass lowers inertia for noticeably quicker engine response and faster revs
• CNC Machined & Dynamically Balanced: Precision CNC machining and computer dynamic balancing ensure smooth, reliable operation at high RPM
• Induction-Hardened Ring Gear: Induction-hardened ring gear teeth maximize service life and resist wear from repeated hard starts
• One-Piece Construction: Single-piece design eliminates common failure points such as warped inserts and loose ring gears, while allowing efficient and uniform heat transfer away from the clutch disc
• Serviceable & Resurfaceable: ACT flywheels can be resurfaced when worn, eliminating the need to purchase additional parts
• SFI 1.1 Certified: Meets SFI Spec 1.1, making this flywheel legal for use at sanctioned drag racing events where SFI certification is required; includes official SFI sticker and serial number
• 12-Month Warranty: Backed by ACT's 12-month limited warranty

ACT XACT Streetlite flywheels are engineered using the latest CAD and Finite Element Analysis (FEA) software to ensure optimal material distribution for maximum strength, lower inertia, superior heat tolerance, and rigidity. Note: Some applications may require use with an ACT pressure plate and disc. Flywheel bolts may be included depending on application — refer to ACT's fitment guide for full details.
