Who Is Redline

The company behind the brand.

Redline Emissions Products, is a brand created by Diesel Emissions Service (DES) to cover the DPF needs in the light, medium and heavy duty diesel market. DES started operations in 2006 as the Emissions Division of parent company North State Truck Equipment, Inc., which has been serving the heavy duty truck market since 1978. DES was established to help California businesses get their trucks compliant and meet or exceed the strict CARB and EPA emissions regulations for their vehicles. With over 15,000 emission control devices sold or installed by DES since 2006, they quickly became the authority on heavy duty emissions systems on the West Coast.

In 2014 DES began manufacturing DPF cleaning equipment under the Filtertherm brand. DES also began stocking one of the largest replacement OEM filter inventories in North America, and began distributing in both Canada and Australia. In 2016, DES launched Redline Emissions Products to meet the growing needs of the light, medium and heavy-duty emissions industry.
