Item Description

With High-Performance Differentials, Axles and Drivelines, by Joseph Palazzolo, you get all the info you need to know as far as choosing the best gear ratio, how to rebuild your differential, and matching driveline components to engine power output.

In addition you will also learn how to set up a limited-slip differential, swap the diff gears and which products are the best for your vehicle's driveline.

High-Performance Differentials, Axles and Drivelines covers Chevy 12-bolt, Ford 8.8-inch, Dana units plus many other high-performance axles and rear ends.

Other coverage includes factory differentials, ring and pinion gears, axle housings, shafts and driveshafts, and U-joints.

A must-have book for anyone wanting to build a high-performance differential.

Book Excerpt: High-Performance Differentials, Axles and Drivelines


The main reason to have a limited-slip differential in your rear axle is to maximize traction on slippery surfaces, such as snow, ice, or mud, which can be exacerbated with an open differential.

Another important reason is to help distribute the torque to the wheels from a high-performance engine and transmission combination. The limited-slip differential transfers torque to both wheels even if one wheel is spinning.

This is a huge improvement over the traction-limited open differential. Limited-slip differentials also maximize acceleration of the vehicle.


To determine whether your vehicle has a limited-slip or an open differential is one of the easiest driveline checks. The first step is to place the vehicle on a flat and level surface, block the front wheels, and raise the rear wheels off the ground with a jack.

As always, practice safety first and place the vehicle on jack stands. Shift the transmission into neutral and make sure that the parking brake is released. Now just rotate one rear wheel in the forward direction and pay attention to the rotation direction of the other wheel.

If it rotates in the same direction (forward), the rear end has a limited-slip differential. If the other wheel rotates in the reverse direction, then the rear end has an open differential. It is that simple.

However, there is one exception: An extremely worn clutch-plate-style limited-slip differential may act like an open differential because the plates are so severely worn. So it's not a totally foolproof test. But this method works for most cases.

SA Design's High performance diffs.
I will always support a veteran owned and Texas based business before any others, because am also a veteran and a native Texan. As far as the books go, as we all know things today cost so much more due to inflation, so I'm the kind of guy that loves to challenge myself with doing projects on my own as to save the cost of labor and markups. I've probably got close to 10 books from SA Design already and they haven't let me down yet. The Motor Book Store is a surefire bet for anyone looking to DIY or just familiarize yourself with automotive knowledge. I already have plans to expand my automotive library for a new project upcoming and I will definitely be utilizing the Motor Book Store again.
