KTS Enterprise: Trusted Diesel Service Across Phoenix & Chandler

KTS Diesel was founded in 2009 with a mission to provide reliable, high-quality diesel repair services for businesses that depend on their fleets. Our journey began as a mobile repair service, responding to fleets in urgent need. As demand grew, we expanded into a full-service operation offering both mobile and in-shop repair solutions. With years of experience, we continue to assist businesses in reducing downtime, preventing costly repairs, and maintaining compliance with industry regulations.

That’s why we provide mobile repairs and maintenance tracking, so you won’t have to worry about coordinating multiple trips or losing track of necessary services.
