Why fit Polybush?
Why use Polyurethane for your suspension requirements?
Polybush are experts in polyurethane.
Polyurethane is an ideal material for making into suspension bushes. Its combination of high tensile strength and elasticity translates into immense durability in the toughest conditions. Polyurethane Bushes have excellent resilience, springing back in to shape effortlessly to absorb shock and prevent dirt ingress and wear. Lastly, it doesn’t age or perish – rubber bushes both perish and are attacked by oils and fuels.
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.
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 quality in on.
Shock bushes can crush down leaving the shock to rattle on its mountings. Polyurethane’s resilience counters this without needing as hard a bush so you can specify the “Touring” grade for all but the most arduous applications.
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.
We Solve Your Problems!
If you are a design and development engineer for vehicle suspension parts, we can solve your problems with a polyurethane material that overcomes the following drawbacks of rubber suspension bushes:
- A too high wear rate
- The high cost of tooling and prototypes
- The long lead time for prototypes
- The wearing away of mating metal parts
- The deterioration due to the effects of petrol and oil
- Poor resilience especially at high hardness
- Poor load bearing and low tensile strength
- High compression set causing permanent deformation
