ACT XACT Flywheel Kit:
ACT XACT flywheels provide significantly improved engine response, acceleration and a higher degree of safety than the original stock flywheels. All ACT XACT flywheels feature a super rigid, trouble free single piece design. This one piece design allows less opportunity for failure and provides for uniform and efficient heat transfer from the clutch, eliminating warped inserts and loose ring gears. ACT XACT flywheels are precisely made using chromoly forgings, also known as chromium-molybdenum steel, a metal which is three times more rigid than aluminum. The materials on ACT XACT flywheels are properly distributed for maximum strength, lower inertia and good heat tolerance. In addition, ACT heat-treats their flywheel forgings for strength and induction-hardens their ring gears for the longest gear life. ACT XACT flywheels are easily serviceable and can be resurfaced without the need to purchase additional parts. All ACT XACT flywheels are SFI certified to meet proper safety measures
