• High friction diamond-infused shims now available for crankshaft damper and fit 6-bolt and 7-bolt 4g63 engines. 
  • This newly available technology increases grip of the joint by a factor of 3-4x bare metal surfaces. 
  • This joint can experience slip during high rpm usage, if high shock loads occur, or when not enough crankshaft bolt clamp load is transmitted through the trigger wheel and damper. 
  • The loads the damper sees increase with both engine torque and rpm. 
  • Recommended in applications above 500ft-lbs torque or above 9000rpm.
  • Two friction shims are needed for maximum grip. 
  • Sold in pairs
