Identifying the Jeep CJ series vehicles as the most popular off-road vehicles of all time may actually qualify as an understatement. They really are that popular. The CJ series arguably started after World War II with the CJ-2A being introduced to the masses, and while the early CJs have their share of enthusiasts, the largest group of enthusiasts began their love affair with the AMC-powered Jeep CJ-5s beginning in 1972. Joined by the longer-wheelbase CJ-7 models introduced in 1976, the CJ models were wildly popular through their discontinuation in 1986, when the Wrangler was introduced. These were the only models originally equipped with V-8 engines in any meaningful way. This era combined the ruggedness of the early Jeeps with some of the advancements and horsepower of a more modern era; it makes a platform that is both fun to own and to modify. In Jeep CJ 1972-1986: How to Build & Modify, Jeep guru Michael Hanssen covers all of the systems that can be upgraded to improve your Jeep's performance. Upgrades include suspension components such as springs, shocks, and steering modifications; driveline components including differentials, transmissions, transfer cases, and axles; engine upgrades including engine swaps; wheel and tire upgrades; aftermarket accessories; armor such as skid plates and bumpers; brake upgrades; and more. Whether you are looking to get into serious off-roading or just want to make your classic CJ a little more fun, this book will be a valuable tool in your shop or library.
