ACT XACT ProLite Flywheel 3SGTE 600390
KORacing Products » Toyota MR2 MK2 » Clutch & Transaxle

These flywheels are now machined to work on both 1st, and 2nd/3rd gen 3SGTEs as well as 5SFE based stroker engines!

Finally a chrome moly flywheel with the best fitment and finish for the 3SGTE engine! And it weighs just 9.7lbs! Quicker revving and better high RPM durability than stock cast flywheels.

  • ACT Flywheels are ligther, stronger and safer than stock cast flywheels to meet the needs of both the enthusiast and hard core racer.
  • Material is properly distributed for maximum strength, lower inertia, good heat tolerance and rigidity.
  • Once 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 our or get damaged like those found in aluminum flywheels.
  • ACT engineers XACT flywheels using the latest CAD and FEA (Finite Element Analysis) software to evaluate all design alternatives for the best possible results.
  • 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.
  • ACT give 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 chambers 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.
  • The XACT Flywheels can be machined for future serviceability.

*NOTE: This flywheel was designed to work on 2nd and 3rd (and 4th) generation 3SGTE Engines as well as 1st gen 3SGTEs and 5SFE cranks.

*NOTE: Use of this flywheel in street applications in combination with the 6 puck clutch will have a greater tendency than the stock flywheel to 'stall' the car when starting from a stop due to its lower inertial weight.
