When you need critical diesel engine components, you need the best products from the best source. Using OEM parts is a wise choice, but you don't have to pay more to get them from a Vehicle OEM dealer. The name brand products that make your diesel's engine perform best can usually be obtained for less from the "Component OEM Distributor," and that's Who We Are! We provide products for most diesel applications including but not limited to our charge-air coolers, diesel turbochargers, automotive turbochargers, fuel injection systems, heavy duty electrical components, filtration and additive products.

From our founder's beginnings in 1950 through today, our group of companies has developed close ties and relationships with the world's leading OEM diesel component manufacturers. Providing superior technical knowledge, state-of-the-art equipment, and a vast range of inventory to help commercial and consumer diesel owners get their equipment up and running quickly and dependably is our main goal.

OEM products are made to highly specific standards, not only to deliver the power owners demand, but also to keep diesel and gas engines performing at top efficiency year after year. With correct parts and regular maintenance, drivers who utilize original equipment parts can depend on the performance and efficiency their vehicles were designed to deliver over the long haul.
