Mantic ER² Clutch and Flywheel Kit is a single disc clutch kit specifically designed for the performance GM LS1 and LS2 vehicles. It features the patented groove design we call ER2, which is CNC machined on the friction face of the pressure plate. Capable of transmitting greater than 60% more torque than a standard clutch kit. Mantic Single Disc Street Clutch with ER2 is suitable for high performance vehicles. Perfect upgrade for any vehicle that wants more holding power than the stock clutch but isn't ready for a dual disc setup.

  • Performance single disc clutch & flywheel combo
  • Capacity: 525 TQ at the Wheels, 607 TQ at the Crank
  • Unique ER2 groove pattern on the friction face of the clutch pressure plate
  • Increase the Mean Effective Radius of the pressure plate 
  • Assist in heat removal for more repetitive abuse
  • Increase in torque capacity
  • Dual friction organic/cerametallic disc
  • ER2 is the best replacement for a stock clutch
  • Mantic ER2 clutch assembly kit includes a lightened steel flywheel, flywheel mounting bolts, pressure plate, sprung dual friction disc, throw-out bearing and alignment tool

Mantic ER2 Advantage

The clutch disc features an organic facing ring in contact with the pressure plate and a segmented ceremetallic facing on the flywheel side. The cover assemble also features a decorative and corrosion resistant finish.

This overall torque capacity increase has been achieved by higher clamp loads, increased Mean Effective Radius of the friction area, better cooling of the pressure plate and higher coefficient of friction materials on the clutch disc. These design innovations directly equate to higher torque capacity.
