{"product_id":"jeep-wrangler-jk-2007-present-performance-upgrades-performance-how-to","title":"Jeep Wrangler Jk 2007 - Present: Performance Upgrades (Performance How-To)","description":"Since its release in 2007, the JK has become wildly popular and nearly 1 \nmillion units have been sold in North America. With a wider track and \nlonger wheelbase, the Wrangler JK is roomier, more comfortable, and \ndelivers better on-road performance than its predecessor. However, it \nneeds serious chassis, suspension, and drivetrain upgrades to tackle \ndemanding off-road terrain and rock crawling.\n\nA full complement of heavy-duty suspension, chassis, steering, \ndrivetrain, and high-performance engine parts has been developed for \nthis platform. Co-authors Don Alexander and Quinn Thomas offer \ncomprehensive guidance for making key modifications and selecting the \nbest parts to transform your JK into a superior off-road performer. Lift \nkits from 1.75 to 5 inches are available, so you can fit off-road wheels \nand tires for exceptional traction. Suspension springs, specially \ncalibrated coil-over shocks, and sway bars must work in concert to \nprovide the correct suspension articulation and ride quality to scale \nobstacles and negotiate terrain. To increase durability and essential \nreliability, pitman arms, drop links, driveline parts, steering boxes, \nand skid plates are examined. Because the drivetrain must be ready for \noff-road service, the authors cover the most rugged and reliable axle \nassemblies available. Exhaust, intake, and electronic engine mapping \nupgrades make the Jeep 3.6- and 3.8-liter V-6 engines much more potent. \nIt also includes how to swap GM LS and new Hemi engines into the JK for \nvastly improved performance.\n\nIf you believe that paved roads are simply access-ways to the open \nrange, you and your JK need this book. It contains the vital information \nto convert any mild-mannered street vehicle into an all-conquering \noff-road rig. Whether it's lift kits, wheels, tires, drivetrain, or \nsuspension and engine parts, this volume provides detailed information, \ninsightful guidance, and installation instructions, so you build an \noff-road JK to handle the toughest terrain.\n\nAuthor BIO\n\nQuinn Thomas\n\nQuinn Thomas has been four-wheeling since the tender age of 17, and by \nage 20, he bought his first Jeep.
