New Products
At Polybush, we strive to deliver high-quality products that offer tangible benefits to both the driving experience and vehicle longevity. That’s why we’re excited to introduce two new items to our lineup: the 44GD Rear Differential Mounting Bush and the 44GE Rear Gearbox Support Bush, specifically designed for the Leon Mk1 Cupra 4, Octavia Mk1 4×4, S3 Mk1 Quattro, and TT Mk1 Quattro.
These vehicles have a strong reputation for being capable and exciting to drive. Still, we noticed a gap in the market for a comprehensive bushing solution to support their suspension systems.
So, we developed these bushings to provide noticeable performance gains, while ensuring they remain suitable for everyday use.
When developing parts for these vehicles, we focused on enhancing the drivability without compromising comfort. These cars are known for their all-wheel-drive systems and dynamic handling, but their standard OEM rubber bushes tend to wear out over time, affecting the precision and performance of the suspension. By adding the 44GD and 44GE bushes to our product range, we aim to help drivers of these models achieve the full potential of their cars.
Our goal was to make these vehicles more enjoyable and reliable for daily use and spirited driving.
Whether you’re tackling tight corners or cruising on the motorway, these bushes will offer the perfect balance between durability, performance, and comfort.
1. Enhanced Suspension Stability
The 44GD Rear Differential Mounting Bush and 44GE Rear Gearbox Support Bush ensure improved stiffness over traditional rubber components. This increase in stiffness leads to more precise handling and greater control, especially under heavy acceleration or cornering, making the car feel more planted and responsive.
2. Extended Durability
Unlike rubber bushes, which degrade over time and with exposure to elements like oil and weather, our polyurethane bushes are designed to withstand harsh conditions and resist wear. The longevity of these components ensures they will last much longer, reducing the need for frequent replacements.
3. Daily Driving Comfort
Though these bushings are performance-focused, they have been engineered to provide a comfortable ride. Polyurethane, while stiffer than rubber, absorbs vibrations effectively without transferring excessive harshness to the cabin. This ensures that your vehicle remains drivable for day-to-day commuting, but with a sharper, more direct feel.
4. Reduced Drivetrain Movement
Both the rear diff and gearbox support bushes play key roles in minimising drivetrain movement. By upgrading to Polybush, you’ll experience less shifting of components during acceleration or deceleration, improving power delivery and reducing wear on other drivetrain components.
5. Increased Vehicle Longevity
Installing these Polybush products can prolong the lifespan of your vehicle’s suspension and drivetrain systems. By reducing flex and movement, there is less strain on the surrounding components, which results in fewer issues and costly repairs down the line.
The choice between polyurethane and rubber bushings is one many drivers face when looking to upgrade their suspension. Here’s why Polybush’s polyurethane bushes come out on top:
1. Durability
Rubber bushes are prone to wear and tear, cracking, and deterioration over time due to exposure to oils, chemicals, and environmental factors. Polyurethane, on the other hand, is highly resistant to these elements, making it a more durable option.
2. Consistent Performance
Rubber tends to soften and lose its shape with time, which negatively affects handling. Polyurethane retains its structural integrity, offering consistent performance even after thousands of miles.
3. Precision and Handling
Polyurethane is stiffer than rubber, which leads to better control and sharper handling. This is especially important in performance cars, where suspension precision can make a big difference to the driving experience.
4. Long-Term Cost Efficiency
While polyurethane bushes may initially cost more than rubber counterparts, their extended lifespan and superior performance make them a cost-effective solution in the long run. Less frequent replacements mean fewer disruptions and lower maintenance costs.
With the introduction of the 44GD Rear Differential Mounting Bush and 44GE Rear Gearbox Support Bush, we’re proud to offer a comprehensive solution that balances both performance and practicality. Whether you’re restoring a Leon Mk1 Cupra 4, modifying an Octavia Mk1 4×4, or enhancing an S3 Mk1 Quattro or TT Mk1 Quattro, Polybush is here to provide you with the reliability, performance, and comfort that these cars deserve.
