All XACT flywheels are certified as meeting SFI® Spec. 1.1 and are legal for competition in all racing organizations where SFI® Certification is required.
ONE PIECE CHROME-MOLY FORGING
One-piece chrome-moly forging allows fewer opportunities for failure and promotes uniform, efficient heat transfer from the clutch disc. This is to prevent warped friction inserts or loose ring gears.
LIGHTER, STRONGER, SAFER
All applications in the XACT Flywheel line are lighter, stronger and safer than OE cast flywheels, meeting the needs of both the enthusiast and hardcore racer.
OPTIMAL MASS DISTRIBUTION
Flywheel mass is distributed optimally for maximum strength, lower rotational inertia, high thermal tolerance and rigidity.
XACT Flywheels have excellent thermal capacity by optimized material support behind the friction surface.
DYNAMICALLY COMPUTER BALANCED
Dynamic computer-spin balancing ensure smooth and predictable performance.
CAD ENGINEERED & FINITE ANALYZED
XACT Flywheels are engineered using the latest CAD and Finite Element Analysis (FEA) software to explore various design alternatives for optimal results.
SMOOTH OPERATION AT ALL RPMS
ACT demands tight tolerances for fit, concentricity and parallelism so flywheels register precisely to crankshaft centerline, allowing smooth operation at all RPM.
MORE WEIGHT REDUCTION, ELIMINATED BREAKAGE
Integral, starter ring gear permits more weight reduction where it matters most and eliminates the chance of gear breakage or separation.
Prolite flywheels are strategically lightened even further, reducing inertia without sacrificing strength or thermal integrity.
Ring gear teeth are cut with lead-in chamfers for first-time starter engagement and to prevent rounded off gear teeth.
HEAT TREATED & TEMPERED
The entire forging is heat-treated and tempered for strength and toughness.
