Boundary 1999 - 2005 Ford Modular Motor 4V V8 Billet Crankshaft Timing Sprocket

MM-SP-4V

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
