, and other LX-platform cars bring modern V-8 performance to unparalleled heights, and the new Challenger and Charger Hellcats are the most powerful American production cars today. The outrageous performance and audacious styling has earned a large and dedicated following. However, you can tune and modify the Chrysler 300, Dodge Magnum, Charger, and Challenger for more performance, and for many owners, fast is not fast enough. In the pursuit of a higher-performing LX-platform car, former Mopar Muscle editor Randy Bolig has created this book to show you how to extract ultimate performance from these cars.

Chrysler has built more than one million Chargers, Challengers, and other full-size-platform cars starting with the Dodge Magnum and Chrysler 300. These cars offer competent handling, braking, and suspension performance, but they can be made much better through a set of targeted upgrades using better aftermarket equipment. Bolig gives you a comprehensive guide to the cars and engines. He details the features, benefits, and drawbacks of each package or set of upgrades, so you select the best modification for your car, application, and budget. He also covers basic to extreme modifications for the R/T and SRT8 models with the 5.7-, 6.1-, and 6.4-liter Hemi engines. Guidance for installing heads, rotating assemblies, ignition upgrades, higher-performance injectors, and many other parts are provided. But, this book doesn't just discuss performance; it shows you how to do it with comprehensive, step-by-step product installs for a cat-back exhaust system, hand-held ignition tuner, cold-air intake, and supercharger.

If you have been searching for the best performance package to make your Charger, Challenger, or full-size Chrysler car stand out from the crowd, you need this book. It has the latest information, so you can learn how to install all the products and get your car back out on the road.
