Polybush began when engineer Roy Higgins got really fed up with changing standard bushes on the Land Rovers he was responsible for in the harsh environment of Africa.
The first step was to design a special tool to remove the old bushes, a tool aptly named BUSHWAKA. Today the extended range of Bushwaka specialist tools are sold and used throughout the world.Having solved the problem of removing the old bushes, Roy set about designing a longer lasting and easier to fit replacement bush. The result was the POLYBUSH CLASSIC and the founding of R H Engineering in 1991.
R H Engineering is now a division of Bonaprene Products Ltd, one of the UK's leading manufacturers of polyurethane elastomers. In fact, Polybush have always been made by Bonaprene Products Ltd in their Wrexham factory.

POLYBUSH CLASSIC
When the POLYBUSH CLASSIC was introduced 7 years ago Land Rover owners found it transformed their vehicles. The superiority of POLYBUSH CLASSIC is due to three key benefits.
Ease of fitting - thanks to its patented two piece design.
Long life - up to five times the life of OE rubber bushes.
Firm control - the tough, super strong POLYBUSH means that steering and suspension movements are crisply accurate.
Literally thousands of Land Rover, Range Rover and Discovery owners from all over the globe have benefited from fitting POLYBUSH CLASSIC. Moreover POLYBUSH CLASSIC have been proven time and time again in the tough demanding world of off-road competition.
Although POLYBUSH CLASSIC are less hard and much longer lasting than their rivals, we have found that some owners want to combine the long life and easy fit of POLYBUSH CLASSIC with the ride characteristics of the vehicle as manufactured.
For these owners it is time to turn to POLYBUSH COMFORT.
POLYBUSH COMFORT
A significant proportion of Land Rover, Discovery and Range Rover owners wanted to combine the ride comfort of the Original Equipment bushes with the long life and easy fitting of POLYBUSH CLASSIC. R H Engineering therefore set their engineers and chemists the task of producing such bushes. The result of their efforts is the POLYBUSH COMFORT range introduced in 1998.
Working closely with their raw material supplier a new grade of Polyurethane Elastomer was developed. After much research, a polyurethane material that is softer and more resilient than any other offered as suspension bushes is now available exclusively from R H Engineering as the POLYBUSH COMFORT range. A royal blue colour distinguishes the COMFORT range from the red of POLYBUSH CLASSIC. The material is proving just as tough and long lasting as POLYBUSH CLASSIC.
POLYBUSH COMFORT bushes were put on trial before general sale. For two years they were tested in the harsh world of off-road competition.
To quote Alan Eland of Overlanders "Not only do POLYBUSH COMFORT give a superb ride on the road, but they have significantly improved performance in off-road competition. Suspension movements and shock absorption are markedly superior without any loss of working life."
POLYBUSH COMFORT will give you:-
A SUPERB RIDE WHICH JUST GOES ON AND ON AND ON ......................................
