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, though they have reduced drivability.
Lighter, stronger, and safer than stock cast flywheels, XACT flywheels meet the needs of both enthusiasts and hardcore racers.
The one-piece construction allows less opportunity for failure and ensures uniform efficient heat transfer from the clutch disc.
ACT heat treats the entire forging 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 needing 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.
