Rubber vs Polyurethane Engine Mounts: What’s the Difference?

  • Rubber vs Polyurethane Engine Mounts: What’s the Difference? / Transgold

Engine mounts generally need replacing after 60,000 to 80,000 kilometres, depending on the driving conditions. Increased vibration and engine noise are tell-tale signs that it might be time for new engine mounts.

It’s important not to ignore the warning signs and to replace worn mounts when necessary – if they fail completely, the engine can tilt and the vehicle will stop.

There are number of different types of engine mounts on the market, including rubber and polyurethane.

What engine mounts do

Engine mounts perform a number of vital functions, including:

  • Holding the engine in place.
  • Stabilising the engine, in turn reducing vibration and creating a smoother and more stable ride.
  • Providing a ‘cushion’ between the engine and car body, reducing wear and tear.
  • Dampening engine noise.

When engine mounts are worn, it can cause increased vibration, strange noises under the bonnet, or even jolts and clunking – especially when changing gears.

The choice of rubber or polyurethane

So what’s the difference when it comes to rubber vs polyurethane engine mounts?

  • Both rubber and polyurethane mounts have around the same lifespan.
  • Rubber is a particularly good material for dampening vibration and absorbing noise. It is also a softer material than polyurethane, providing a superior cushioning ability.
  • There is no need to grease rubber mounts, unlike polyurethane ones that will need regreasing every few years.
  • Polyurethane mounts may have a noticeable squeak during driving.
  • It’s also relatively easy to do DIY installation of rubber engine mounts.

Rubber engine mounts are durable and cost effective. At Transgold, we believe rubber offers a number of benefits over polyurethane across a range of products, including engine mounts and suspension products.
