The FAS Crank Pin Kit is a critical reliability upgrade for any Hellcat platform running increased boost, smaller upper pulleys, or aggressive tuning. The factory crank is prone to slip under load, which can throw off timing, damage the crankshaft, or cause catastrophic engine failure. This kit eliminates that risk by securely pinning the crankshaft and ensuring the balancer stays locked in place no matter how hard the car is pushed.
Precision-machined components, OEM-fit tooling, and a straightforward installation process make this kit ideal for both street and high-horsepower builds. Whether you’re running a mild pulley swap or a full race setup, this is the insurance your Hellcat needs to stay consistent, safe, and ready for more power.
