ACT flywheels are lighter, stronger and safer than stock cast flywheels to meet
the needs of both enthusiast and hard core racer. Material is properly
distributed for maximum strength, lower inertia, good heat tolerance and
rigidity. One piece construction allows less opportunity for failure and
provides uniform efficient heat transfer from the clutch disc. No more warped
inserts or loose ring gears.
Integral ring gear permits more weight
reduction where it matters most and eliminates the chance of gear breakage or
separation from the flywheel. Precision machined threads will not easily strip
out or get damaged like those found on aluminum flywheels.
engineers XACT flywheels using the latest CAD and FEA (finite element analysis)
software to evaluate all design alternatives to get the best results possible.
By hot forging chrome-moly steel, each flywheel yields an ultra fine centralized
grain structure that is superior in strength to any other manufacturing method.
Timing marks are precisly located and clearly displayed (when applicable).
Ring gears are cut with
lead-in chamfers for better starter engagement and prevention against rounding
off gear teeth.
Engineers at ACT demand tight tolerances for fit,
concentricity and parallelism so that flywheels will have an exact fit onto the
crankshaft, and operate smoothly even at extremely high rpm.
flywheels are CNC machined and dynamically computer balanced for super smooth
high RPM reliability.
