About JP Magazine

Established in 1996, Jp Magazine has become the world's largest Jeep-only brand -- an entertaining, do-it-yourself manual of sorts aimed at Jeep owners looking for ideas and insight into modifying, restoring, maintaining their Jeep. Jp also unabashedly celebrates Jeeps and the Jeep lifestyle and does it all in an entertaining, fun, and sometimes controversial way.

Each issue of Jp contains features on the hottest and most outrageous Jeep builds, product information and shootout comparisons, how-to features, and performance testing. Jp also covers the biggest Jeep shows and 4X4 events across the U.S. and beyond – including trail rides, mud bogs, off-road competitions and Jeep-centric racing. From the latest Jeep concept to out-of-production models such as the legendary CJ and early Cherokee, from the enthusiast's driveway to the showroom floor, if it's Jeep related, Jp is there, with extensive coverage designed to inform, engage, and involve Jeep enthusiasts, wherever they are.

Jp Magazine also has inside access to Jeep designers and engineers, often relaying what Jp loyalists have to say about the latest Jeep and Mopar concept vehicles as well as their ideas and concerns around present and future production models. Few magazines have the ear of those in the position to give Jeep enthusiasts what they want and need like Jp Magazine does.

The Jp editorial staff of is comprised of real Jeep enthusiasts with extensive hands-on wrenching experience who communicate to readers in a lively and engaging manner. They live on the trails, help set the trends and are immersed in the Jeep lifestyle. Their project Jeeps take readers through the entire process, from buying to building to hitting the trail, with features ranging from “What if...?” to creating a powerful Jeep on a shoestring budget.

Bottom line, if you're into Jeeps in any way, shape or form, there is no better place to find what you're looking for -- in print or on the Web -- than Jp.
