Dusterhoff Racing DT877 Trackhawk Power Package

The Dusterhoff Racing DT877 Trackhawk Power Package is a complete, engineered performance solution designed specifically for the 2018-2021 Jeep Grand Cherokee Trackhawk equipped with the 6.2L Supercharged Gen 3 HEMI engine. This package is built for enthusiasts who want a proven, reliable, and fully integrated upgrade path that delivers real-world performance gains without the guesswork of piecing together individual parts. With carefully matched components and Dusterhoff Racing’s custom calibration, the DT877 transforms the Trackhawk into a significantly more aggressive, responsive, and powerful SUV while maintaining excellent drivability for daily use.

At the core of this package is a combination of airflow, fueling, and boost-enhancing upgrades that work together seamlessly. The Dusterhoff Tuning Upper Pulley Kit increases supercharger speed to generate additional boost, while the included fuel injectors ensure the engine receives the proper fuel delivery to support the added airflow and power demand. A heavy-duty belt is included to maintain reliable pulley operation under increased load, and the 180-degree thermostat helps reduce engine operating temperatures for improved consistency during spirited driving or track use. These hardware upgrades are paired with a PCM Unlock Service, HP Tuners RTD with credits, and a Smart Access Cable, giving Dusterhoff Racing full control over the factory ECU for precise calibration.
