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.
