Diesel Emissions Service

DES has been at the forefront of on-road emissions technology since CA mandated its new emissions standards nearly 20 years ago. DES operated as a full-service repair shop and salvage yard since the 70s, before specializing in emissions repair in 2006. DES has several repair shops on the West Coast where we focus on emissions services including retrofits, DOC & DPF cleanings, and diagnostics. We also stock a large inventory of both OEM and aftermarket emissions parts in order to minimize downtime.
