Billet Crank Sprockets from Boundary follow 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 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 snug 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 at 170 grams vs 130 grams giving the highest strength sprocket on the market.
- High finish reduces friction and chain vibration
- New tooth geometry strengthens teeth and keyway
