Family-Owned Diesel Service Across
Phoenix & Chandler Since 2009
KTS Diesel was founded in 2009 to provide reliable diesel fleet maintenance and repair for businesses that depend on their trucks every day. What began as a mobile diesel repair service has grown into a full-service operation offering both mobile and in-shop support for commercial fleets in Phoenix and Chandler.
We help businesses keep Class 6 to 8 trucks on the road with fast service, accurate diagnostics, and preventative maintenance that reduces downtime and costly breakdowns.
We understand the pressure fleet managers face when a truck is down. Delayed deliveries, lost productivity, compliance risks, and rising operating costs all impact the bottom line.
That’s why KTS Diesel focuses on practical fleet solutions, including mobile repairs, maintenance tracking, DOT compliance support, and efficient in-shop repairs that help businesses stay organized, reduce cost per mile, and avoid unnecessary interruptions.
Businesses trust KTS Diesel because we combine honest communication, transparent service, and fleet-focused support built around uptime. Whether you need mobile fleet repair, preventative maintenance, or ongoing diesel service for your operation, our goal is simple: keep your trucks moving and your business running.
