Product Description

The Boundary MM-SP-GT500 Billet Crankshaft Timing Sprocket is engineered for the Ford Shelby GT500 (2007-2014) fitted with the 5.4L or 5.8L Ford Modular V8 engine. Manufactured in the USA from high-grade chromoly steel, this sprocket offers significantly enhanced strength over the factory powdered-metal unit--making it an excellent choice for high-boost, high-RPM, or motorsport engine builds.

With a larger cross-section at the keyway, heat-treated construction and precision machining, the MM-SP-GT500 supports the demands of serious performance applications while maintaining direct OEM fitment. Whether you're installing a built bottom end, a high-output supercharged system or prepping for drag or road-race use, this upgrade helps ensure timing chain and crank sprocket integrity under extreme loads.
