What Is the Difference Between Aluminum and Steel Driveshaft Parts?

In order for a vehicle to go faster, it needs an engine that is capable of producing more horsepower. That is the basic mechanics that we all know.

However, what most people forget about is what happens when the extra power is transferred to the wheels? Will the driveshaft parts handle the extra power?

For any increase in power, the vehicle’s driveshafts need to be upgraded also! Driveshafts come in two basic materials: Aluminum and steel! Each has its own advantages for upgrading a standard driveshaft! Read on below to find out those advantages.

About Aluminum Driveshaft Parts

6061-T6 Aluminum driveshafts are the type of metal you will likely find for a vehicle with aftermarket upgrades. Aluminum driveshafts offer improvements on their steel counterparts but are not without their own disadvantages.

Advantages

• Weight reduction of 10 to 20 pounds
• Improves power to weight ratio
• More engine power as the driveshaft is less weight to rotate
• Improved longevity in your engine
• Resistant to rust
• Doesn’t wear at the same rate as rust

Disadvantages

• Weaker metal than steel
• Shears when breaks
• Doesn’t reduce vibration or noise
• The ride isn’t as comfortable 

About Steel Driveshafts

The most common type of driveshaft that you will find on vehicles straight from the factory is a steel driveshaft. Vehicle manufacturers use steel driveshafts for a few reasons but this metal can have a downside to it too.

Advantages

• Relatively inexpensive to purchase
• Effectively dampens noise and vibrations
• Durable against continuous punishment

Disadvantages

• Heavier than other metals
• Puts more strain on your vehicle’s engine
• Reduced power to weight ratio

Which Driveshaft to Use?

Picking the right metal for your driveshaft will depend on what you want to use it for and where the vehicle is driven. If your vehicle is driven continuously in harsh winter conditions then you will need a high performance driveshaft that is made out of aluminum and not steel.

An aluminum driveshaft will be also preferred if you are racing with the vehicle and want a vehicle that is as light as possible. For a standard everyday car, a steel driveshaft would be better because steel is relatively inexpensive, and spare parts can be sourced easily. 

If you do have a 4×4, for example, aluminum driveshafts would do you no good. Steel is a much stronger material and would be able to withstand the constant punishment of a 4×4 trail much longer than an aluminum one would. Taking all this into account will help you make a decision in no time.

Make the Right Choice for Your Vehicle

Having the right driveshaft parts in place can make or break the power transfer from the engine to your wheels. Getting the setup correct is vitally important for the longevity and overall riding experience of your car.
