The WJ, was the second generation Grand Cherokee offered by Jeep for model years 1999-2004, and continued to add-on new features and technology which increased fuel economy and safety, while also improving its off road capabilities and overall power. A unibody design stuffed with driver conveniences such as adjustable pedals and dual zone climate control, was still able to go off-road reasonably well. Six and Eight cylinder engines were the base of the many sub models like Laredo, Limited, Overland and Sport, all offering feature packages with better upholstery and soundsystems. Body panels and chassis parts are still available to keep the WJ on the road. Whether you need brake parts, from the wheel cylinder to the booster or hard to find suspension parts, Quadratec® has the Essentials® in organized, easy to follow diagrams showing the parts which are available and how they relate to each other.
