Managing an electric vehicle fleet is all about reducing downtime, controlling maintenance costs and maximising vehicle availability. Whether you’re operating taxis, delivery vans, company cars, rental vehicles or your maintenance fleet, every hour a vehicle spends off the road affects your bottom line.
While electric vehicles eliminate many traditional maintenance items such as engine servicing, suspension wear remains one of the biggest ongoing maintenance costs. In fact, the additional weight of EV battery packs often accelerates wear on suspension bushes and related components, especially on vehicles with high annual mileage.
At Polybush, we’ve developed a long-lasting solution: we manufacture British-made polyurethane suspension bushes specifically designed to outlast conventional rubber bushes, helping fleets reduce replacement frequency, lower maintenance costs, and improve vehicle reliability.
Today, we supply suspension bushes for a growing range of electric vehicles, including:
…and we’re continually expanding our range as more electric vehicles enter fleet service.
Electric vehicles place unique demands on suspension components.
The instantaneous torque produced by electric motors increases loading on suspension arms during acceleration, while regenerative braking imposes repeated stress on suspension geometry during deceleration. The biggest factor, however, is weight – Most EVs weigh significantly more than their petrol or diesel equivalents due to the battery pack. That extra mass means suspension bushes work harder over every pothole, speed bump and corner; For example, the Nissan Leaf weighs half a ton more than that of a Nissan Micra, which, as we know, are similarly sized vehicles.
For high-mileage vehicles such as taxis, private hire vehicles, delivery vans and commercial fleets, this can lead to:
Replacing worn rubber bushes every few years quickly becomes an expensive and time-consuming maintenance cycle.
That’s where Polybush changes the equation.
Unlike conventional rubber bushes that deteriorate with age, oil contamination and environmental exposure, Polybush polyurethane bushes are engineered to deliver consistent performance for significantly longer. Our unique polyurethane formulation has been refined over decades of manufacturing in the UK and is trusted by enthusiasts, workshops and fleet operators worldwide.
This results in:
Exactly what every fleet manager wants.
If you’re replacing tired, perished rubber bushes, Polybush polyurethane bushes are a smart long-term investment.
Standard rubber bushes naturally soften, crack and perish over time.
Polybush bushes resist:
This means substantially longer service life, particularly on vehicles covering high annual mileage.
For fleets, fewer replacements directly translate into lower maintenance costs and reduced vehicle downtime.
Polybush bushes are engineered to reduce unwanted suspension movement without compromising comfort.
Benefits include:
For commercial vehicles carrying passengers or cargo every day, maintaining predictable handling is an important safety benefit as well as improving driver confidence.
Many people assume polyurethane bushes create a harsh ride – Not ours!
Our unique formulation is designed to retain original equipment ride comfort while delivering noticeably improved suspension control.
Whether it’s a LEVC taxi navigating city streets all day or a Tesla covering motorway miles, comfort remains a priority.
Unlike many polyurethane bushes on the market, Polybush bushes are designed to be installed dry.
There’s:
Once fitted, they’re designed to simply get on with the job.
Every Polybush product is manufactured in the UK to exacting standards using our proprietary polyurethane formulation.
Our manufacturing quality is backed by ISO 9001 accreditation, giving fleet operators confidence in every component we produce.
Fleet maintenance isn’t just about parts prices.
It’s about total operating cost.
Every suspension bush replacement involves:
By fitting longer-lasting suspension bushes, fleets can reduce replacement intervals and spend less time taking vehicles off the road.
Over the life of a fleet, those savings can become significant.
For taxi operators, delivery companies and commercial vehicle fleets, increasing component lifespan often delivers a better return than simply choosing the cheapest replacement part.
Longevity is one of the themes that comes up time and again in customer feedback.
Our Trustpilot reviews consistently highlight how Polybush products continue performing long after conventional rubber bushes would have needed replacing.
Customers regularly praise:
Many customers report fitting Polybush bushes once and simply forgetting about them, with vehicles continuing to perform reliably for years afterwards.
For fleet operators, that’s exactly the outcome you’re looking for.
Reliable vehicles spending more time earning money and less time in the workshop.
Polybush bushes are particularly well suited to:
Whether you’re managing five vehicles or five hundred, reducing maintenance frequency helps improve profitability.
We already manufacture suspension bushes for many of the UK’s most popular electric fleet vehicles including:
As electric vehicle adoption continues to grow, we’re committed to expanding our range to support even more fleet operators.
Choosing Polybush means benefiting from:
Electric vehicles may require less servicing than traditional vehicles, but suspension components remain one of the biggest wear items, especially on heavier, high-mileage fleet vehicles.
Rather than repeatedly replacing worn rubber bushes, upgrading to Polybush provides a proven long-term solution that helps reduce maintenance costs, improve reliability and keep vehicles on the road for longer.
For fleet managers, workshops and operators looking to reduce whole-life running costs, Polybush offers a suspension solution that’s built to outlast and outperform conventional rubber.
Because the best maintenance job is the one you don’t have to repeat.
