Boundary Modular Motor 4V / 3V Billet Crank Sprocket Multi Keyway
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 are checked after machining and after heat treatment for a guaranteed fit.
- High finish reduces friction and chain vibration
- New tooth geometry strengthens teeth and keyway
The Multi-keyway allows cam centerline adjustment up to 4 degrees in either direction without integrated spacer
