Billet Crankshaft Timing Sprocket Ford Mod Motor V8 4V Integrated Spacer Boundary Pumps

This product is for the Ford OEM with an integrated spacer. This product is needed for a OEM timing system (tone wheel) as the spacer is not built into the tone wheel.

Billet Crank Sprockets from Boundary follows the same heritage as our oil pump gears, manufactured 100 percent 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 a guaranteed fit.
• High finish reduces friction and chain vibration
• New tooth geometry strengthens teeth and keyway
