Your truck's engine.
Our obsession.

Diesel expertise that keeps you on the road
Whether you need a routine oil change or a complete engine overhaul, our certified technicians treat every truck like it's their own.
Diesel Diagnostics
Advanced OBD scanning and computerized analysis to pinpoint issues fast — from glow plug failures to turbo boost leaks.
Engine Repair & Rebuild
Complete diesel engine service including fuel injection, turbocharging, head work, and full rebuilds on all major brands.
Oil & Fluid Services
High-mileage diesel oil changes, filter replacements, and fluid top-offs using premium products that extend engine life.
Brake & Suspension
Heavy-duty brake inspections, pad and rotor service, and suspension repairs built to handle the weight of your rig.
Electrical Systems

Pre-Purchase Inspections
Buying used? We put the truck through a thorough 50-point inspection so you know exactly what you're getting before you commit.
Trucks ready to work
Our lot rotates regularly. Every truck in our inventory is inspected and road-ready before it hits the lot.

Built on honest work
Speedworx Motors started with a simple idea: truck owners in East Tennessee deserve a shop that actually understands diesel — not just a place to pass inspection.
We combine a curated truck sales lot with a full-service diesel repair bay so you never have to choose between finding the right rig and keeping it running right. Same address. Same phone. One call handles both.
Located on Broad Street in Cleveland, we've spent years building relationships with local fleet operators, contractors, and families who rely on their trucks every single day. When your engine light comes on at 6 a.m., we're already here.

Drivers who trust us
"My 6.7 Cummins was throwing codes that two other shops couldn't crack. Speedworx had it running smooth the same afternoon. Fair price, no upselling — just good work."
— M. Thompson

"Bought a used F-250 from them and they did the pre-buy inspection before I even signed. Caught a turbo leak the seller didn't mention. That's the kind of honesty you don't find everywhere."
— D. Rutherford

"I run a small landscaping business with three work trucks. Speedworx keeps all of them on the road. They treat my fleet like it matters, and that's rare."
