Triplet Diesel Injection began operation in March of 1996 in Waco, TX with a commitment to provide Central Texas with quality customer service. This goal, along with a strong service support and knowledgeable factory trained technicians, has allowed for continuous growth.

Triplet Diesel has had a strong drive in service from day one, giving us a unique ability to solve customer engine problems because we have been in your shoes and know what really works and what does not work. We also have a strong presence in the turbo charger industry. We do all rebuilding, balancing and machine work in house.
