What we do
Every service that keeps your fleet moving.
We'd rather be great at a few things than mediocre at everything. These are the services we run every day, with the parts in stock and the techs who know them.
DOT Inspections
Federal DOT inspections done right. We handle annual inspections, follow-up corrections, and fleet PM programs that keep your trailers compliant year-round.
Learn more →Brake Repair
Brake systems for box vans and trailers. Slack adjusters, air lines, chambers, drums, shoes. We diagnose fast and fix it right the first time.
Learn more →Reefer Service
Reefer trailer repair — doors, gaskets, insulation, floors, lights, and brakes. We keep the box sealed and road-ready. The trailer, not the cooling unit.
Learn more →Structural Repair
Frame, floor, wall, door, rear-frame damage. From scrape repairs to major rebuilds. Welding, alignment, and refurbishment done in-house.
Learn more →Mobile Service
On-site repair across our service area. When pulling the trailer to the shop costs more than the fix, we come to you. Trucks dispatched same day.
Learn more →Parts Counter
Real parts inventory. Brands you trust, in stock at the counter. Walk-in or have your mechanic call ahead and we'll have it ready.
Learn more →For fleets with in-house mechanics
Your mechanics handle the basics. We handle the backlog.
The Knox Trailers Fleet Overflow Program: when your bay is full and your tech is backed up, we take the work off your plate so your fleet stays moving. Recurring relationship. Predictable scheduling. Your team focuses on what only they can do.

Real parts. In stock. At the counter.
Brake chambers. Slack adjusters. Reefer parts. Lights, mud flaps, suspension components. The parts your mechanic needs today, not three days from now. Walk in, or call ahead and we'll have it ready when you pull up.
Built in Knoxville. Since 1993.
We're not a chain. We're a shop.
Knox Trailers has serviced and repaired trailers in East Tennessee since 1993. We don't own fleets — we keep them on the road. Every system we've built, from how we schedule emergency work to how we keep parts in stock, comes from one focus: getting your trailer fixed right and back in service fast.
About Knox Trailers →Downtime costs more than the repair.
Whether it's a DOT inspection coming due, a brake job on hold, or a reefer that won't hold temp — call us first. Most fleets save more in one truck-day than they spend with us in a month.
