Boundary Coyote Crankshaft Timing Sprocket with Grip Surface

The Coyote crankshaft timing sprocket with grip surface improves the durability of the crankshaft snout and keyway by limiting the movement of the harmonic balancer.

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 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 are checked after machining and after heat treatment for a 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
