Billet Crankshaft timing sprocket for the QR engine

The Billet Crank Sprockets from Boundary follow the same heritage as their oil pump gears, manufactured 100% in house with US sourced materials. These sprockets start with a chromoly steel that is 10 times stronger then the OEM powdered metal, hot quenched with a low temper for the highest strength and resistance to wear.

  • All sprockets heat treated to maximum hardness while maintaining toughness
  • Precision CNC machined and broached for accurate fit
  • Dimensions checked after machining and after heat treating for guaranteed fit.
  • 80% more cross section versus OEM at the keyway
  • Weighs 30% more then OEM
  • High finish reduces friction and chain vibration
  • New tooth geometry strengthens teeth and keyway
