Magnus McLaren Friction Washer



Grip Sticker Make You Quicker


When hp and tq is increased, it can cause the M840T flywheel to be damaged from fretting.  This movement of the crankshaft flange against the flywheel surface will destroy your crankshaft and flywheel very quickly.  We developed a friction washer to combat this, and increase the friction between the two surfaces.  Magnus washers increase friction between the flywheel and crankshaft. The friction washers increase the coefficient of friction between two fastened surfaces and can allow as much as 4x higher torque to be transmitted. This allows the components to withstand increased shear forces associated with making more torque.


  • Not affected by oil films
  • Increases maximum load and peak torque of bolted joints.
