The ROUSH Phase 2 supercharger upgrade kit makes the outstanding performance of our 2015-2017 F150 5.0L V8 Phase 1 supercharger system even better by adding proven core components and careful calibration. This kit provides an additional 50 horsepower and 28 lb-ft of torque when installed with our 600 hp/ 557 lb-ft Phase 1 supercharger system (PN 421983).
