Boundary Coyote Crankshaft Timing Sprocket

Billet Crank Sprockets from Boundary follows the same heritage as our oil pump gears, manufactured 100% in-house with US-sourced materials. These sprockets start with a chromoly steel that is ten times stronger than 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 snug accurate fit
  • Dimensions checked after machining and after heat treatment for guaranteed fit.
  • 80% more cross-section versus OEM at the keyway
  • Weighs 30% more than OEM at 170 grams vs 130 grams giving it the highest-strength sprocket on the market.
  • High finish reduces friction and chain vibration
  • New tooth geometry strengthens teeth and keyway
