The Basics of Aluminum Driveshafts

The driveshaft is the link between power and torque from the transmission's output shaft to the differential's pinion yoke, where it transfers to the wheels and tires. It is an essential component of vehicle operation. Although it would be safe for the vehicle to go anywhere without one, that statement could also be made about many other components.

A driveshaft is subject to a lot of stress, especially in high-performance racing situations. They must be strong, straight, and durable. It's also important that the driveshaft is as light as possible in race cars.

Aluminum

Aluminum driveshafts have a primary advantage due to their lightweight characteristics. It is more about the ends than the tube that results in weight savings over similar steel shafts. The driveshaft's initial imbalance is improved by lighter material. However, the residual imbalance can affect the driveshaft critical speed. This is the RPM at which the driveshaft vibrates uncontrollably.

A long, thin driveshaft that resonates at high speeds will become apparent. Aluminum is lighter than steel, so it can be thickened to make it more stable, without sacrificing performance due to increased inertia.

While acceleration and speed are certain bonuses, the aluminum driveshaft's key benefits include reduced vibration damage.

Aluminum's weight is a benefit, but it is also less strong than steel. Driveshafts made of aluminum will wear faster than other materials. To make the shafts stronger, manufacturers perform work-hardening. Although some hardening can make the material more durable, it is not enough to prevent the shaft from failing.

Understanding the operating range of your driveshaft is a key factor to maintaining it in top condition.
