What Our Customers Say
Used STI for the first time last week for my Kenworth. Did the oil change and brakes and tires. Got me in quick and Sam was great to work with. Trustworthy guys. I will be back.

These guys kick ass. They took care of my trailer and got me back on the road. The price was lower than I expected whats not to like. Don’t remember the mechanics name but he was good.

Saw the ad on Facebook and gave them a try. Seriously good mechanics. Don’t bother with another shop. If you’re in the Lee’s Summit area, then you owe it to yourself to take your truck here.


They get you right in and keep the bill low!

These mechanics are top notch. Did a great job on my truck.

STI is the real deal. I was having overheating issues with my T680 and starter problems. The guys at STI got me right in. Super nice guys. I have found my new mechanic shop. Recommended!

Great shop. Super nice! Been coming here for about 3 years. They know me by name and always do a great job! The diesel mechanics really know their stuff.

I can’t say enough about STI Truck Repair! Hard working mechanics & technicians. Honest and dependable!
