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.
- 80% more cross-section versus OEM at the keyway
- Weighs 30% more than OEM
- High finish reduces friction and chain vibration
- New tooth geometry strengthens teeth and keyway
Includes 2 sprockets: one to drive the oil pump and one to drive the cam.
