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
