PFF5-1322 Gearbox Mounting Bush Insert is made using the same Yellow 70A durometer material and has been designed to fill the voids in the OE mount for an effective and affordable solution to stiffening the original rubber. As the vehicles ageand simple upgrades seeing the2-ltrturbo engine push power north of 250bhp, the OE rubber engine and transmission mounts are showing their age, with cracked rubber and excessive movement.PFF5-1322Gearbox Mounting BushInsertis made using the sameYellow 70Adurometer material and has been designed to fill the voids in the OE mount for an effective and affordable solution to stiffening the original rubber.
WHY POLYURETHANE SUSPENSION BUSHES?
Time to do some sums…
Polyurethanes have been with us since the late 1930s, however, recent advances have now made it possible to engineer very special properties into this exciting material.
Suspension bushes are some of the most highly stressed components fitted to a motor car. They undergo enormous strains and in the most arduous of conditions with no maintenance or lubrication.
The material they are manufactured from is a rubber compound containing natural products that deteriorate with age. It becomes softer and more pliable, resisting the forces placed on it less and less. Therefore allowing more and more movement of suspension components and offering less and less control over the suspension geometry.
This in turn causes accelerated tyre wear, braking instability, and poor handling. This is the single biggest reason you can instantly tell the difference driving a three-year-old car compared to a showroom new one. However, even new cars will benefit from POWERFLEX bushes because of the superior design they offer much more effective control of the suspension components to a much greater extent than normal rubber items.
With the technological advances in this material, it has been possible to overcome the common problem associated with harder bushes which is 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.
- POWERFLEX bushes make sense.
- POWERFLEX for improved performance.
- POWERFLEX for increased safety.
- POWERFLEX for prolonged tyre life.
