Jeep Wrangler JK (2007 - Present) : Advanced Performance Modifications

Since its release in 2007, the JK has become wildly popular and nearly 1 million units have been sold in North America. The Wrangler JK is roomier, more comfortable, and delivers better on-road performance than its predecessor. However, it needs serious chassis, suspension, and drivetrain upgrades to tackle demanding off-road terrain and rock crawling.
A full complement of heavy-duty suspension, chassis, steering, drivetrain, and high-performance engine parts has been developed for this platform.

Co-authors Don Alexander and Quinn Thomas offer comprehensive guidance for making key modifications and selecting the best parts to transform your JK into a superior off-road performer.
Lift kits from 1.75 to 5 inches are available, so you can fit off-road wheels and tires for exceptional traction. Suspension springs, specially calibrated coil-over shocks, and sway bars must work in concert to provide the correct suspension articulation and ride quality to scale obstacles and negotiate terrain.

To increase durability and essential reliability, pitman arms, drop links, driveline parts, steering boxes, and skid plates are examined. Because the drivetrain must be ready for off-road service, the authors cover the most rugged and reliable axle assemblies available.
Exhaust, intake, and electronic engine mapping upgrades make the Jeep 3.6- and 3.8-liter V-6 engines much more potent. It also includes how to swap GM LS and new Hemi engines into the JK for vastly improved performance.

If you believe that paved roads are simply access-ways to the open range, you and your JK need this book. It contains the vital information to convert any mild-mannered street vehicle into an all-conquering off-road rig. Whether it's lift kits, wheels, tires, drivetrain, or suspension and engine parts, this volume provides detailed information, insightful guidance, and installation instructions, so you build an off-road JK to handle the toughest terrain.

Jeep Wrangler JL & Gladiator JT: Performance Modifications

The Wrangler version of the Jeep was transformed with the release of the JK for the 2007 model year. With a more practical 4-door version, this Wrangler became a popular vehicle for year-round use, which appealed to off-roaders as well as soccer moms.
For the 2017 model year, Jeep seriously upgraded the Wrangler, which is now dubbed the JL, and added an exciting new model, the Gladiator, or JT, which is essentially a pickup version of the Wrangler.

In this book, Jeep experts Don Alexander and Quinn Thomas introduce you to these new models and walk you through the capabilities and options for all of the trim levels. Then, they examine how to make these things better, system by system. Suspension, steering, and brakes are covered, as they are the heart of any off-road rig.
Also examined are modification options for axles, driveshafts, and differentials as well as bumpers, armor, and protection. Of course, off-roaders need a quality winch, recovery gear, and upgraded electrics, so options are explored here as well.
Wheels and tires are also very important for those leaving paved roads, and upgrade options for all of the trim levels and lift levels are covered thoroughly.

Whether you want to build a JL or JT to be a serious rock crawler or simply look like you are going off-road, all of your options are thoroughly explained in this book.
