Drivetrain setup continues to be a baffling and controversial subject. It's baffling because it's three-dimensional, and it's controversial because differing applications require differing solutions.

Building a hot rod means working all the angles, and there are plenty of angles to work. One of the more important angles is the angle between your transmission output shaft (which is the same as the ...

One of the most common causes of torsional vibrations has to do with driveline angles between the transmission and front and rear drive axles. Since your drive axles may be a long way from the engine ...

Why do we have to think about these angles at all? We wouldn't if the engine, transmission, driveshaft, and pinion all shared the same centerline. As it is, these components are never on the same ...
