Jeep's petrol range comprises the Pentastar V6, the Hemi V8 and turbo four-cylinders. The Trackhawk and SRT have significant potential with supporting hardware. Jeep shares engines with Dodge and Chrysler.
With supporting hardware, the Trackhawk confidently reaches Stage 2. The Jeep community in the US offers a large pool of ready-made Stage files for off-road use.
