Knox Performance Diesel & Off Road provides maintenance, diagnostics and repair for diesel work trucks serving Killeen, Fort Hood and Central Texas. We work on Powerstroke, Cummins and Duramax trucks and help you catch problems before they turn into more downtime.

Your employees don’t need to be diesel techs, but they should know what to look for and what to report.
We’ll help your team recognize warning lights, leaks, smoke, unusual noises, changes in how a truck runs, and other signs that shouldn’t be ignored.
We’ll also provide a simple pre and post trip checklist, so drivers have an easy routine to follow and know when to flag a truck for attention.

From routine maintenance to hard to find problems, we can help with:
We document what we find with photos and clear recommendations, so you can decide what needs attention now and what can be planned for later.

Fix it on your schedule, or it’ll pick its own.
