PNM's newly designed Poly gearbox mounts can be used on all Esprit's from '81 including V8, giving extra longevity and performance.

Some aftermarket mounts cause excess vibration. Ours are designed and tested on our own cars to give the right balance of performance, comfort and longevity.

These gearbox mounts have been tested on our own V8 to ensure they don't suffer from the vibration which is present from harder aftermarket bushes.

Product testing has included temperature strip analysis of heat levels from gearbox to mount which proved to be well within limits required.

Kit consists of 2 polyurethane gearbox mounts.

Made by Polybush exclusively for PNM.

Polybush are an original supplier of polyurethane bushes to Lotus.

Also used as dry sump Esprit Engine Mounts.

Dispelling the myths behind Polyurethane bushes.

“Polybushes are too hard”

A common misconception about Polyurethane bushes is that they are too hard and give a harsh
uncomfortable ride. This isn’t the case. Before a bush is created the mechanical properties of the
relevant suspension and the bush itself (including its hardness) are tested and considered to ensure
that the new product will live up to, and more often than not surpass the original OE part.
Although not often considered, one of the key characteristics of polyurethane is the range of
hardness that can be created. During the manufacturing process the hardness can be controlled
based on the application and purpose of the product, for example: our stiffest grade of polyurethane
will give you precise steering and a controlled ride at all speeds – The ideal solution for fast road
driving, track and towing. On the other hand our more elastic solution will give you greater
longevity, and greater shock absorption than its stiffer counterparts. “There’s a hardness for that”.

“Polyurethane bushings are too expensive”

Polyurethane bushings are resistant to water, grease, ozone and road damage and will outlive
rubber bushes by a considerable amount. They are referred to as “fit and forget” products due to
this huge longevity. Our bushes have a long service life and their performance does not degrade over
time and due to this do not need replacing like the rubber equivalents making Polybush a cost saving
option. An example of the cost saving potential is a solution created for West Midlands Ambulance,
the vehicles were suffering from premature bush wear and the bushes were not available to buy
separately. Due to this full replacements of anti roll bars and leaf springs were being carried out on a
regular basis. Once the need of full replacements was illuminated, a cost saving of £700 on parts
alone per vehicle became possible.
