Product Description

The Boundary CM-SP-15-GRIP is a billet crankshaft timing sprocket built for 2015+ 5.0L Coyote-powered Mustangs and F-150s. Machined in-house from US-sourced Chromoly steel - ten times stronger than the factory powdered metal unit - it addresses a common failure point on forced-induction Coyote builds, where crankshaft keyway overload can lead to snout cracking and complete failure.

With 80% more cross-section at the keyway and a grip surface that limits harmonic balancer movement, it's designed to keep your crankshaft reliable under the added stress, heat, and RPM that come with superchargers, turbos, or centrifugal blowers. Precision CNC machined and broached for a guaranteed fit, and manufactured entirely in the USA.
