Hellion Twin Turbo Kit for 2012-2022 Grand Cherokee SRT

Add serious boost potential to your HEMI platform with the Hellion Hidden Twin Turbo System. Engineered for both performance and fitment, this system delivers smooth, responsive power while maintaining a clean, factory-style appearance under the car. It’s designed for enthusiasts who want strong, consistent boost without sacrificing drivability or everyday function.

Key Features:

• Hidden design: The system mounts discreetly under the vehicle, keeping the engine bay uncluttered and maintaining a stock-like look.

• Twin turbochargers: Dual turbos provide fast spool and broad power delivery, offering excellent throttle response and strong mid- to top-end performance.

• Complete bolt-on system: Includes intercooler, piping, oil lines, clamps, and hardware — everything needed for a proper installation.

• High-quality construction: Stainless steel piping, TIG-welded connections, and precision-machined components ensure durability and consistent results.

Want it installed? Our technicians can install it at our shop in Marengo, IL, and we tune it on our in-house chassis dyno, by appointment. Street tuning dials in drivability.

Not local? Many Mopar and Ford combinations can be tuned remotely with HP Tuners.

Submit a work request and we'll confirm fitment, install and tuning for your car. Shop rates are listed on our Rates & Terms page.
