Powerflex Rear Differential Front Mounting Bush

Factory fit bushes are manufactured from a basic rubber compound containing natural products which deteriorate with age. Bushes therefore become softer and more pliable, resisting the forces placed on them less and less and subsequently allow more and more movement of suspension components leading to less control over the suspension geometry.

Suspension bushes are some of the most highly stressed components fitted to a motor car and they undergo enormous strains, in the most arduous of conditions with no maintenance or lubrication. This in turn can cause accelerated tyre wear, braking instability and poor handling. This is the single biggest reason you can tell the difference driving a three-year-old car compared to a showroom new one.

Polyurethane has been with us as a specialised plastic for decades but recent advances have made it possible to engineer very special properties into this exciting material. These technological advances make it possible to overcome the common problem associated with harder bushes like reduced control and increased noise. By correctly engineering the polyurethane compound, bushes can be made 25-30% stiffer than new rubber items but with exactly the same noise absorbing properties.

Important

We sell over 250,000 performance car parts online! Sadly, it is impossible for us to stock all of these parts all of the time and ultimately this would only lead to increased prices.

All of our listings offer an estimated delivery date which is made up of the dispatch timeframe and the delivery service used but please understand that these dates are not guaranteed and occasionally delays do happen. Sometimes a part may have to be manufactured or even imported from another country for you. Where we are informed of a delay we will do our best to keep you updated.

In rare circumstances we may even have to cancel an order if a part is no longer being produced by the manufacturer and we cannot source it for you. We cannot guarantee product availability. If you wish to check please contact us before ordering.

Please do not schedule any work on your vehicle until you have received and fully inspected your parts.
