Erentek Products







An important part of our business is designing and supplying conversion kits for a variety of vehicles, including agricultural tractors and farm trailers, crop-sprayers, other agricultural vehicles, trucks, tractor units, semi-trailers, and other commercial or industrial vehicles.
The conversions are mainly for air braking systems, hydraulic braking systems and air suspension systems, plus other related conversions such as tyre-inflators and air-assisted doors.
Each kit comes with a layout drawing and parts list, plus our full technical backup.
We can design a new system or modify an existing system to improve its performance or to comply with the latest construction and use regulations and EU legislation, for example, some farm trailers are either underbraked or have no working brakes at all, and we can supply a conversion to suit the customer's requirements.





Anti-lock braking systems (ABS) are now commonplace, on agricultural as well as commercial vehicles, and many of these systems need upgrading. We also supply lift-axle conversions and suspension-lowering systems for vehicles with air-suspension, using the latest electro-pneumatic devices.
No two conversions are identical, and our speciality is in designing each system for the vehicle.
Listed below is a representative selection of conversions we have carried out, but there are many more, in fact over the last few years, we have designed over 400 individual conversion kits, complete with drawings and parts lists. So if you need advice or further information on any conversion work, just give us a call on 01522 720065.
