101 – THE BASICS

The Jeep Grand Cherokee WK2 epitomizes the pinnacle of American SUV craftsmanship, blending iconic design with cutting-edge innovation and formidable performance. Forever seen an Australian roads as the “gangsta” SUV option, our focus at ECC is based around the renowned 392ci HEMI v8, symbolizing raw power and precision engineering.

Since its debut, the Jeep Grand Cherokee WK2 has offered enthusiasts the option to harness the relentless force of the HEMI v8 engine, distinguishing itself as a true performance-oriented SUV. This engine, known for its displacement and hemispherical combustion chambers, delivers uncompromising performance across various driving conditions. Whilst the earlier WK1 models are getting a bit long in the tooth, the WK2 and its 6.4litre Gen 2 Hemi v8 is a popular combination for aftermarket modification, and an awesome alternative for those seeking some american muscle and not travelling down the GM or Ford route.

Jeep has continuously refined the HEMI engine, incorporating advanced technologies like Multi-Displacement System (MDS) and Variable Valve Timing (VVT) to enhance efficiency without sacrificing power. This commitment to innovation ensures that each Grand Cherokee WK2 model delivers exhilarating performance and efficiency in equal measure, and responds well to upgrades from a company that is experienced in this platform.

Release of the WL platform with the new Gen 3 5.7L HEMI engine is also. supported, and once again, requires a niche approach and skillset to ensure success when modifying here.

At ECC, we offer a comprehensive range of tuning support, engine enhancements, and exhaust modifications tailored to enhance the capabilities of Grand Cherokee WK2 models equipped with both the Gen 2 6.4L HEMI engine (SRT) and the later model Gen 3 5.7L HEMI variants. When modifying this platform, it is crucial to choose a workshop that is experienced with the Dodge / Chrsyler / FCA network and infrastructure, as many workshops who think they can modifyand tune these things “just like an LS” have caused more problems than solutions for most. Luckily, ECC has been at the forefront of modifications on this platform for over a decade, tuning some of the first forced induction Jeeps in the country, and and regularly called upon to assist, fix, andtune vehicles all around the country from others that have tried and failed.

Whether you areseeking increased power, improved handling, reliability, enhanced exhaust note, or driveline and suspension upgrades, our expertise ensures your Grand Cherokee WK2 remains at the forefront of SUV performance.

In summary, the Jeep Grand Cherokee stands as a testament to American automotive excellence, combining rugged capability with sophisticated design and advanced technology. As ECC continues to support Jeep enthusiasts with bespoke solutions and upgrades, we invite you to explore the unrivaled performance and versatility of the Grand Cherokee WK2 with one of the few companies in Australia qualified to achieve the outcomes you desire.

EVERYTHING YOU NEED TO KNOW WHEN MODIFYING THIS PLATFORM

Whilst it seems to be a bit of an industry standard, to look at modification paths for a car based on bundles of modification, commonly referred to as “stages”. We have found at ECC that this isn’t always the case, with all builds being different in their own right, and comparing “stages” is generally not a great like for like comparison when there is no regulation between what a workshop will include in said stages.

For this reason, why have put together this basic modification and upgrade guide, which should walk you through the basics of what you need to know when modifying this platform. Specifically, the best ways to go about things and more importsntly, what NOT to do, toensure you dont make expensive or costly mistakes when commencing this journey.
