Redeye Stage 2 Kit w/ 3.17-Inch Hellephant Pulley

The Mopar Performance Direct Connection Redeye Stage 2 Kit is engineered as a comprehensive performance upgrade for the Hellcat Redeye. This kit unlocks the vehicle's potential by increasing engine performance to an impressive 885 horsepower and 787 lb-ft of torque, as measured per SAE J1349 correction factor. This significant power gain is achieved through a high-performance, factory-tuned calibration that enables high-octane functionality, particularly when utilized in conjunction with the required Redeye Pre-Stage Kit. Included in this kit is a 3.17-inch diameter Hellephant pulley, which contributes to a 2 lb increase in boost pressure over stock specifications. The calibration key code provided with the kit is essential for unlocking the Stage II calibration, fully realizing the performance enhancements. It is important to note that when the high octane mode is not engaged, the expected performance output is 837HP. Installation of this kit requires dealer expertise and is estimated to take between 2 to 3 hours. Please be aware that Direct Connection Calibrations are exclusively for U.S. vehicles. Furthermore, this Stage 2 Kit necessitates the separate purchase of the Redeye Pre-Stage Kit.
