Product Description

The **Boundary CM-SP-15** is a high-strength billet crankshaft timing sprocket built for Ford's 5.0 L Coyote V8 that debuted in 2015 and beyond. This sprocket replaces the OEM powdered-metal unit with one made from chromoly steel - significantly stronger and more durable, especially under high-stress or high-RPM conditions.

With a thick, heat-treated cross-section and a precisely broached keyway, the CM-SP-15 is engineered to resist wear and deformation, even when paired with upgraded oil pump gears or high-performance build components. Its mirror-polished surface reduces friction and improves stability, making it a go-to upgrade for performance-focused Coyote builds.
