Now in its third edition, Jeep 4x4 Performance Handbook eliminates the mystery of getting the most out of your Jeep vehicle, thanks to the thorough research and expertise of Jeep experts Jim Allen and James Weber—with updates to address a decade of new technologies, vehicles, and the exploding overland adventure hobby. The world of high-performance Jeep ownership can be challenging.

The authors explain the parts, swaps, modifications, and tech that will give you the most bang for your buck, whether you hit the trail in a CJ, Wrangler (TJ and YJ), Cherokee, Liberty, one of the many classic and vintage Jeeps available—heck, even the 2020 head-turning Gladiator pickup. Jeep 4x4 Performance Handbook is also completely updated to cover the latest advice and techniques for planning and negotiating overland routes and digital technologies that will help you get the most from your four-wheeling experience. Considerations such as trail etiquette and communications options ensure you are equipped to handle nearly any trip, no matter how far into the wilderness you choose to venture. The worlds of off-road driving and overland adventure have never been hotter.
