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. |
 |
 |
ACT 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). |
 |
 |
ACT gives extra effort to strategically slot XACT ProLite flywheels to lower inertia without sacrificing strength and heat dissipation. |
 |
 |
ACT heat treats the entire forging for strength and toughness, and induction hardens their ring gears for longest gear life. |
 |
 |
XACT Flywheels are certified as meeting SFI Specification 1.1. XACT Flywheels are legal for competition in all racing organizations where SFI certification is required. |
 |
 |
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. |
 |
 |
All flywheels are CNC machined and dynamically computer balanced for super smooth high RPM reliability. |
