The benefits of polyurethane suspension bushes
In part two of Polybush’s article, following on from Ellis Blackman’s explanation about why polyurethane is the company’s solution to premature bush failures, he dives into the strengths of the material and shares some stock recommendations.
Polyurethane suspension bushes offer many advantages, making them a suitable choice for performance, durability and cost effectiveness.
Polyurethane has longevity and durability; it is resistant to oil, road salt and UV radiation. Its high tensile strength also prevents tearing, making it particularly suitable for performance and off-road applications where durability is paramount.
Another advantage of polyurethane bushes is their ability to improve handling and stability. By reducing unwanted movement in the suspension, they provide a sharp steering response and more predictable handling. This is especially beneficial for performance vehicles, 4x4s, and towing applications, where precise control is crucial.
Temperature stability is another factor that gives credence to polyurethane; it maintains its properties across a wide temperature range, ensuring consistent performance in all weather conditions.
Polyurethane bushes are also available in multiple hardness options, allowing for customisation based on specific vehicle needs:
• Comfort (OEM equivalent): Suitable for daily-driven vehicles, maintaining ride quality while offering improved longevity.
• Dynamic (OEM and upgrade): Balances performance and comfort, reducing suspension deflection for sharper handling.
• Performance: Designed for motorsport and high-performance road cars, providing minimal flex for maximum precision.
However, for some applications, only one grade of material is offered to ensure proper vehicle operation. Due to tight suspension tolerances, this is usually a harder material to meet performance demands.
Cost-effectiveness is another significant benefit of polyurethane bushes. While they have a higher initial cost than rubber, their lifespan means fewer replacements over time. Additionally, the improved suspension control helps prevent premature tyre wear and component failure, ultimately saving money in the long run.
Stock recommendations
You can enhance both profits and customer satisfaction by stocking the right selection of replacement bushes. Prioritising high demand applications ensures workshops and customers have access to essential parts when needed. The applications and parts below are in high demand:
• Ford Transit (V362): Front lower arm and rear spring bushes.
• Nissan Juke, Qashqai, Leaf: Front lower wishbone rear bushes.
• Mazda MX-5 ND: Rear hub bushes. Unlike the OEM, which requires replacing the entire hub, Polybush provides bush replacements, saving customers a lot of money.
• VW, Audi, Seat and Škoda: Front lower wishbone bushes, a common failure across all models.
• Ford Fiesta Mk7: Rear axle bushes.
• Classic car applications, like the MGBGT and Triumph TR series.
Polyurethane upgrade kits:Offering full suspension kits allows workshops and customers to replace all wear-prone bushes at once, reducing repeat visits and ensuring only one alignment is required.
Performance and off-road stock: Motorsport and off-road enthusiasts often seek upgrades for enhanced handling and durability. We supply suspension bushes for standard road cars, performance vehicles and 4x4s.
Bespoke and universal solutions: For custom builds and restorations, we also supply universal bushes and polyurethane rods, catering to cases where standard-fit bushes are unavailable.
Conclusion
If you are looking to enhance your product offerings and reputation, investing in polyurethane suspension bushes is a strategic decision. They offer durability, performance, and long-term value.
By understanding common failure points, stocking the right products and educating customers on the benefits of polyurethane, you can strengthen customer trust, increase sales and ensure vehicles remain safe and reliable for longer. Whether for a fleet of Transits, a cherished classic car, or a high-performance sports vehicle, we believe polyurethane represents the future of suspension bushes.
