Why Upgrading to FG Falcon Diff Bushes Can Improve Handling and Reduce Noise

The Ford Falcon FG is known for its performance, comfort, and robust engineering. However, as with any vehicle, upgrading certain components can significantly improve both handling and driving experience. One such upgrade that can make a noticeable difference is the replacement of the differential (diff) bushes. These relatively simple components are often overlooked, but they play a crucial role in the car's suspension system. In this article, we will explore why upgrading to FG Falcon diff bushes can enhance handling, reduce unwanted noise, and improve overall driving dynamics. FG Falcon diff bushes

<h3>What Are Diff Bushes and Their Role?</h3>
Before diving into the benefits of upgrading, it&rsquo;s important to understand what diff bushes are and their role in the suspension system. The differential (diff) is a key part of a vehicle&rsquo;s drivetrain, transferring power from the engine to the wheels while allowing them to rotate at different speeds&mdash;crucial for smooth cornering. The diff is connected to the vehicle&rsquo;s body via diff bushes, which are rubber or polyurethane bushings that serve as mounts between the diff and the chassis.

These bushes help absorb vibrations and road noise, while also allowing for slight movement in the diff as it transfers power to the wheels. Over time, as the car is driven, the diff bushes can wear out due to the constant stress and heat they are subjected to. When this happens, the bushes can become soft, cracked, or deformed, causing a range of issues such as poor handling, excessive noise, and uncomfortable driving experiences.

<h3>The Benefits of Upgrading to FG Falcon Diff Bushes</h3>
Upgrading to performance-oriented FG Falcon diff bushes, particularly polyurethane ones, can provide several advantages over the standard rubber bushes. Below are the key reasons why this upgrade is worth considering.

<h4>1. Improved Handling and Stability</h4>
One of the most significant advantages of upgrading to FG Falcon diff bushes is the improvement in handling and stability. The factory rubber diff bushes, while sufficient for regular driving, tend to deteriorate over time. As they soften or crack, they allow for increased movement in the diff, leading to a less precise connection between the differential and the car&rsquo;s body. This can result in undesirable suspension movement, especially during hard acceleration, braking, or cornering.

Polyurethane diff bushes are stiffer and more durable than rubber, offering better resistance to wear and tear. When installed, they provide a firmer connection between the diff and the chassis. This reduces unwanted movement, allowing the differential to maintain a more consistent alignment during dynamic driving conditions. The result is improved cornering ability, reduced body roll, and better overall stability when driving aggressively or in high-performance scenarios.

In simple terms, upgrading to stiffer diff bushes helps to keep the rear end of the vehicle more planted, ensuring the tires maintain better contact with the road, even when the car is pushed to its limits.

<h4>2. Better Power Transfer</h4>
As mentioned, the differential is responsible for transferring power from the engine to the wheels. When the diff bushes wear out, this power transfer becomes less efficient, as the diff is not securely held in place. This can result in a loss of power delivery, leading to inefficient acceleration and handling.

Upgrading to high-performance FG Falcon diff bushes helps to ensure that the differential is securely mounted, reducing any excessive movement. This ensures that power is efficiently transferred to the wheels, improving acceleration and responsiveness. In a performance-oriented car like the FG Falcon, this means quicker launches, better acceleration through corners, and more responsive handling overall.

<h4>3. Reduction in Noise and Vibration</h4>
The diff bushes are also responsible for isolating vibrations and noise generated by the drivetrain. When the factory rubber bushes wear out, they lose their ability to absorb these vibrations effectively. This leads to an increase in noise and a more uncomfortable driving experience, especially at higher speeds or during hard cornering.

Upgrading to polyurethane diff bushes can greatly reduce this problem. Polyurethane is much stiffer and denser than rubber, meaning it is more effective at dampening vibrations. The result is a quieter, smoother ride with fewer annoying droning noises from the rear end of the car. Although some enthusiasts might notice a slightly firmer ride, the overall reduction in noise is often a welcome improvement for those who drive long distances or on rougher roads.

<h4>4. Longevity and Durability</h4>
One of the primary reasons why people upgrade to FG Falcon diff bushes is for the increased durability they offer. Factory rubber bushes degrade over time, especially in harsh driving conditions or with high-performance driving. Exposure to heat, UV light, and general wear causes rubber to soften, crack, and break down. As a result, they need to be replaced more frequently, leading to additional maintenance costs.

Polyurethane bushes, on the other hand, are highly durable and resistant to wear and tear. They can withstand higher temperatures, are more resistant to oil and solvents, and have a longer lifespan compared to rubber bushes. This means that once you upgrade to polyurethane diff bushes, you can expect them to last much longer, reducing the need for future replacements and ultimately saving you money in the long run.

<h4>5. Enhanced Driving Comfort</h4>
Although polyurethane bushes are stiffer than rubber, they still offer a level of comfort that many performance-oriented drivers find appealing. The increased stiffness enhances handling performance, but it also improves driving comfort by reducing the amount of unnecessary diff movement that can cause uncomfortable sensations when driving. Without the excessive play in the diff, the car feels more solid and planted on the road, improving both control and comfort.

Moreover, as polyurethane diff bushes are more efficient at isolating vibrations, you&rsquo;ll notice less &ldquo;bounciness&rdquo; or jarring from the rear end of the vehicle. For drivers who use their FG Falcon for both daily driving and performance purposes, this blend of improved handling and increased comfort is often a key selling point for the upgrade.

<h4>6. Improved Safety</h4>
A car that handles more predictably is a safer car. Worn-out diff bushes can cause the car to feel unstable or unpredictable, especially in dynamic driving situations such as high-speed cornering or rapid acceleration. This lack of control can potentially lead to dangerous situations, particularly in emergency maneuvers.

By upgrading to FG Falcon diff bushes, you ensure that the rear end of the vehicle remains stable, even under heavy load. This predictability and control can significantly improve driver confidence, making the vehicle safer to drive in all conditions, from daily commuting to spirited weekend drives.

<h3>What to Consider When Upgrading to FG Falcon Diff Bushes</h3>
While upgrading to performance diff bushes offers significant benefits, there are a few considerations to keep in mind before making the change. First, polyurethane diff bushes can result in a slightly firmer ride due to their increased stiffness. While this is generally beneficial for performance, it may not be ideal for those prioritizing a soft, comfort-oriented ride.

Additionally, it&rsquo;s important to choose high-quality diff bushes from a reputable brand. Not all polyurethane bushes are created equal, and subpar options can lead to premature wear, excessive noise, or other issues. Be sure to invest in a well-made set of bushes to get the full benefits of the upgrade.

<h3>Conclusion</h3>


Upgrading to FG Falcon diff bushes is an effective way to improve the vehicle&rsquo;s handling, reduce noise, and enhance overall driving dynamics. By replacing the factory rubber bushes with more durable and performance-oriented polyurethane bushes, you&rsquo;ll notice improvements in power transfer, stability, and overall ride quality. The added benefit of a quieter, smoother ride makes this upgrade a great choice for anyone looking to enhance their FG Falcon&rsquo;s performance and driving experience, whether on the track or the road. If you&rsquo;re looking to get the most out of your vehicle, upgrading to FG Falcon diff bushes is an investment that will pay off in terms of both performance and long-term durability.
