Redline Emissions

Redline Emissions Products is a subsidiary brand of Diesel Emissions Service (DES) that focuses on providing Diesel Particulate Filter (DPF) solutions for the light, medium, and heavy-duty diesel market. DES originated in 2006 as the Emissions Division of its parent company, North State Truck Equipment, Inc., which has been serving the heavy-duty truck market since 1978. The establishment of DES aimed to assist businesses in California in ensuring compliance with the stringent CARB and EPA emissions regulations for their vehicles. With a track record of selling or installing over 15,000 emission control devices since 2006, DES quickly became a trusted authority on heavy-duty emissions systems along the West Coast. 

In 2014, DES expanded its operations by introducing the Filtertherm brand, specializing in manufacturing DPF cleaning equipment. Additionally, DES built one of the largest inventories of replacement OEM filters in North America and extended its distribution network to include Canada and Australia. Recognizing the increasing demands of the light, medium, and heavy-duty emissions industry, DES launched Redline Emissions Products in 2016.
