Hellion Twin Turbo System - 2018–2021 Jeep Grand Cherokee Trackhawk 6.2L

The Hellion Twin Turbo System for the Jeep Grand Cherokee Trackhawk (WK2) delivers an entirely new level of performance for one of the most aggressive factory SUVs ever built. Designed specifically for the supercharged 6.2L Trackhawk platform, this system replaces traditional power adders with a true bolt-on twin turbo solution capable of rewriting horsepower and ET records.

Hellion was the first company to introduce turbo systems for modern Mopar platforms, and that experience is on full display in this Trackhawk-specific kit. While superchargers offer immediate response, they place constant parasitic load on the engine. Hellion’s twin turbo design instead uses spent exhaust energy to generate boost, delivering increased efficiency, stronger top-end power, and improved drivability—without overworking the engine.

The twin turbochargers are positioned close to the engine for ultra-fast spool and massive torque production across the entire RPM range. With AWD traction and adjustable boost, this setup transforms the Trackhawk into a street-dominating, track-ready SUV that accelerates harder and pulls longer than any supercharger-only configuration.

This complete bolt-on tuner kit installs using common hand tools and requires no cutting or permanent vehicle modification. Large-diameter 3-inch piping, a high-efficiency air-to-air intercooler, and Hellion’s proven oiling system ensure consistent performance whether cruising on the street or making full-power passes at the track.

Boost control is fully adjustable from inside the vehicle using the included Turbosmart e-Boost3 controller. Dial the system down for conservative street driving or turn it up when conditions allow—no pulley swaps, belt changes, or mechanical downtime required. With proper supporting modifications, this system is capable of producing extreme horsepower levels while remaining reliable and daily drivable.

Each system is sold as a tuner kit and does not include programming or fuel system components. Our team can assist with tuning and fuel recommendations to match your performance goals.
