XACT Prolite flywheels are the lightest offering from ACT with the lowest inertia.
Designed for best throttle response and acceleration, Prolite flywheels are preferred for road racing or rally racing and have reduced drivability.
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.
The entire forging is heat treated by ACT for strength and toughness, while the ring gear is induction hardened for the longest gear life.
XACT flywheels are serviceable and can be resurfaced without the need to purchase additional parts.
Certified as meeting SFI Specification 1.1, ACT's XACT flywheels are legal for competition in all racing organizations where SFI certification is required.
