Jeepers rejoice! Bring new life to your classic Jeep YJ with this new guide to off-road performance.

More than 685,000 YJs were built from 1986 to 1995. They featured heavier wider leaf springs, track bars, and sway bars for improved handling. A massive range of parts are offered for these vehicles, which include lift kits, wheels up to 37 inches, larger brake rotors, high-performance aluminum remote reservoir shocks, stronger driveshafts and U-joints, and Dana 60 conversions.

In Jeep Wrangler YJ 1987-1995: Performance Modifications, veteran author Don Alexander covers the 4.0 engine, transmissions (automatic and manual), transfer cases, axles, differentials, and driveshafts, steering boxes, brake upgrades, shocks, springs and lift kits, chassis strengthening, and interior upgrades.

Whether you want to do some simple upgrades, such as a lift and tire combination, or want to go all out with a rock crawler-style suspension and an engine swap, this book will guide you through the process.
