XACT Flywheel ACT 600640 Streetlite

XACT flywheels from ACT are considerably lighter than stock and are the most durable offering from ACT.

For maximum strength, lower inertia, good heat tolerance, and rigidity, materials are properly distributed.

Preferred for street or drag racing, ACT's Streetlite flywheels are designed for strength, affordability, and improved engine response.

Lighter, stronger, and safer than stock cast flywheels, XACT flywheels meet the needs of both the enthusiast and hardcore racer.

With one piece construction, there is less opportunity for failure and uniform efficient heat transfer from the clutch disc is achieved.

The entire forging is heat treated by ACT for toughness and strength, while the ring gear is induction hardened for the longest gear life.

Serviceable XACT flywheels can be resurfaced without needing to purchase additional parts.

Certified as meeting SFI Specification 1.1, XACT flywheels are legal for competition in all racing organizations where SFI certification is required.
