"William is a awesome guy. He did a great job. Called about the tandem axle not sliding and helps me fixed some other little issue. I definitely recommend austin fleet services"

Jackson Epalle

"These guys are great, had an emergency with a DEF pump on a black Friday, only shop that picked up the phone, took my driver in immediately and didn't give me the runaround like most do now. I asked not to diagnose anything and just change the pump. Truck back on the road in 3-4 hours and saved us at least 3 days waiting for another shop to open. Definitely coming back here next time our  trucks are in the area!"

Vlad Supron
