When you're on the road hauling freight or managing a fleet, the last thing you want is unexpected downtime.

Based in Junction City, OR, we specialize in heavy-duty trucks, trailers, and diesel engines, offering on-site repairs that come to you when it matters most.
Founder and lead technician Daniel Stone knew his path early on. Growing up with a passion for engines and machinery, Daniel began his career in high school and never looked back. He earned his degree in Diesel Technology while working at a dealership, where he maintained and repaired semis. In 2021, Daniel launched Twisted Wrench Mobile Repair.
