A British Manufacturer of Polyurethane Suspension Components
Polybush is the suspension division of Bonaprene Products Ltd, a family-owned polyurethane manufacturer with more than 34 years of experience in advanced polymer engineering.
Operating from our purpose-built 30,000 sq ft manufacturing facility in Wrexham, we design, test and manufacture all Polybush products in-house. This complete control over production allows us to maintain consistent quality, tight tolerances and dependable supply.
Unlike many aftermarket brands that import generic components, our bushes are developed specifically for each application to ensure proper fit, correct movement and long service life.
Why Polyurethane Suspension Bushes Are Better Than Rubber
Traditional rubber bushes deteriorate over time due to heat, oil contamination and repeated suspension movement. Polyurethane offers significant advantages for modern and classic vehicles alike.
Polybush polyurethane bushes:
Resist oil, petrol and road contaminants
Maintain their shape without compression set
Improve steering precision and suspension control
Reduce premature wear of surrounding metal components
Last significantly longer than conventional rubber bushes
In real-world use this means tighter handling, fewer suspension knocks and a bush that doesn’t degrade
Designed for Real-World Driving
Suspension components must strike the right balance between durability, comfort and control. Polybush bushes are engineered to allow the suspension to move as intended while eliminating the premature wear commonly seen in rubber components.
Our range includes bushes for:
Anti-roll bars
Control arms and wishbones
Suspension springs
Shock absorbers
Subframes and mounting points
Each design is tuned for its specific location within the suspension system so that handling improvements never come at the expense of excessive noise or harshness.
Built for Enthusiasts, Workshops and Engineers
Polybush products are used by:
Independent garages and suspension specialists
Classic car restorers
Motorsport teams
Off-road and expedition vehicle builders
Automotive design and development engineers
For specialist applications, we can also manufacture custom polyurethane bushes and components, offering rapid prototyping, low tooling costs and short development lead times.
Quality You Can Trust
Quality is at the core of everything we manufacture. Our polyurethane formulations are developed to deliver high resilience, excellent wear resistance and consistent performance in demanding environments.
Every Polybush component is produced using carefully controlled manufacturing processes and tested to ensure it meets our strict durability standards.
The result is a suspension bush designed to last significantly longer than conventional alternatives while improving vehicle stability and driving feel.
Supporting Drivers Around the World
From daily drivers to competition vehicles, Polybush suspension bushes are fitted to thousands of vehicles worldwide.
Drivers choose Polybush because the difference is immediately noticeable:
tighter steering response, improved body control and a suspension system that feels solid again.

Anti Roll Bar Bushes
You need the resilience of polyurethane to ensure a tight fit to the bar. This avoids knock and squeaks from loose bushes and minimises wear. The “Comfort” grade is best for this, but the “Performance” grade is best if you want to reduce body roll and sharpen up the steering.
Control Arm Bushes
Polyurethane’s elasticity allows control arms to move as intended whilst its tensile strength soaks up punishment from cornering, braking, accelerating and poor road surfaces. Go for a “Comfort” grade bush to preserve ride quality for longer, or choose the harder “Performance” grade to improve body control and steering. If there’s no choice, we’ve already chosen the best material for your vehicle.
Spring Bushes
Spring bushes are subject to the same forces as a control arm bush, as well as supporting the weight of the vehicle. Polybushes, with their combination of strength and elasticity, improve bush life and ride stability and quality .
Shock Bushes
Shock bushes can crush down leaving the shock to rattle on its mountings, changing alignment. Polyurethane’s resilience counters this whilst still reducing Noise Vibration & Harshness. (NVH)
Mounting Bushes
All the vehicle’s moving components cause noise and vibration so Polybush makes a range of mounting bushes for steering, suspension, engines and transmissions. The polyurethane isolates these unwanted buzzes and rattles but holds the components firmly in place improving ride smoothness and body control.
