Searching for the perfect performance tailshaft and feeling lost? You’re not alone. 

Whether you’re a car enthusiast chasing peak performance or need a reliable upgrade for your daily drive, knowing what to look for in a tailshaft is vital. 

Let’s simplify the process and help you make an informed choice

Introduction to Performance Tailshafts

On the hunt for a performance tailshaft? 

Maybe you’re aiming to boost your car’s power, enhance its durability, or replace an old part. 

Whatever the reason, picking the right tailshaft can transform your vehicle’s performance and longevity. 

At GJ Drivelines Keysborough, we’ve got the expertise to guide you. 

Here’s why tailshafts are so crucial…

What is a Tailshaft, and Why is it Important?

A tailshaft, or driveshaft, is a vital part of your vehicle’s driveline system. 

It transmits power from the transmission to the differential, driving the wheels. 

Simply put, without a functioning tailshaft, your car isn’t going anywhere.

Now, let’s find the perfect one for you.

Types of Tailshafts: Which is Best for Your Vehicle?

When it comes to performance tailshafts, you have several options. Here’s a quick overview:

Steel Tailshafts

Steel tailshafts are strong and reliable, perfect for heavy-duty use. They can handle a lot of torque but are heavier, which might affect your vehicle’s performance. If durability is your priority, steel is the way to go.

Alloy Tailshafts

Alloy tailshafts are lighter than steel, making them ideal for high-performance vehicles. The reduced weight can significantly enhance your car’s acceleration and handling. If speed and efficiency are your goals, alloy is your best bet.

Carbon Fibre Tailshafts

The premium option, carbon fibre tailshafts, are both lightweight and incredibly strong. They come with a higher price tag, but the performance benefits are worth every cent.

Key Considerations for Choosing a Tailshaft

Keep these factors in mind when selecting a performance tailshaft:

  1. Material: The material affects both weight and strength. Consider what you need based on your vehicle’s use—daily driving, racing, or hauling.
  2. Size: The length and diameter of the tailshaft must match your vehicle. Incorrect sizing can lead to poor performance or even damage other parts of your driveline.
  3. Power Capacity: Ensure the tailshaft can handle your engine’s horsepower and torque. A tailshaft that can’t keep up will wear out quickly and could fail when you need it most.

The Value of Custom Tailshafts

While off-the-shelf tailshafts might do the job, custom tailshafts are the best choice for those serious about performance. 

At GJ Drivelines Keysborough, we customise each tailshaft to meet your vehicle’s specific needs. 

This ensures optimal performance, durability, and a perfect fit every time.
