Millions of GM vehicles were built and sold in the 1970s, and the great majority of those were rear-wheel-drive models with differentials known as 10 Bolts or 12 Bolts. High-performance limited-slip versions of these differentials also have been installed in Firebirds, Formulas, or Trans Ams, and many other GM cars. If you have owned a GM performance car from the 1960s or 1970s, you have owned one of these sturdy, reliable, and versatile differentials.

Many of these differentials are now more than 40 years old and are due for an overhaul. In this book: How to Rebuild the 10 and 12 Bolt, author Jefferson Bryant walks you through the entire process of disassembling, evaluating, and rebuilding the perfect differential for your GM application. In this step-by-step guide, you learn how to completely disassemble the differential, evaluate components, and select replacement parts. You're also shown all of the up-to-date techniques for re-assembling the differential and axle. Informative sections on axle identification and replacement parts are also provided.

Maybe you have found a salvage-yard unit and want to rebuild it to upgrade your existing vehicle. Maybe you would like to install an aftermarket 12-bolt assembly for extreme performance or racing. This is the only book dedicated solely to rebuilding, setting up, and or modifying these axle assemblies for long service life and maximum performance. If you're going to rebuild a GM 10 or 12 Bolt axle, this book delivers the essential information to get the job done right. Order your copy today!
