Behrang Ulu is agricultural land and produces seasonal fruits such as durian, mangosteen and petai.
Its rubber lands are no longer lucrative and have given way to newer industries including car manufacture.
Bandar raya Proton or Proton City was created based on an agreement between the government of Perak and Selangor to develop Lembah Bernam (Bernam Valley). Proton City was created for the production of Gen 2 cars after the Shah Alam plant was operating at maximum capacity and further expansion needed a new site.
