What we service on Kenworth and Peterbilt trucks

KW and Pete share a lot under the hood, and we work on all of it: PACCAR MX-13 engines and the Cummins options many owners spec instead. Diagnostics for check engine lights and derates, aftertreatment work on DPF and regen problems, cooling system repairs, belts and hoses, batteries, starters, and alternators.

Beyond the engine, we handle air systems when the truck won't build air, full brake jobs, clutch and driveline concerns, suspension and steering wear, lighting, and the wiring problems that make gauges and sensors act up. If your truck runs the Magic Valley hauling milk, beets, or hay, we've likely fixed the same problem on a rig like yours.

Common trouble spots, stated plainly

On modern emissions-era trucks — PACCAR and Cummins alike — the aftertreatment system is the most frequent headache we see across the industry: plugged DPFs from short runs and long idles, sensor faults, and derates that cut power at the worst time. Cold weather adds gelled fuel and battery failures.

We don't guess and we don't invent problems. We diagnose, show you what we found, and quote the fix before we touch it. The price we quote is the price you pay.

Shop bays or mobile service

Bring your KW or Pete to our Jerome bays, minutes off I-84 exit 168, or call us out. Our mobile trucks cover every I-84 exit from Bliss to Declo, and we state a flat call-out fee before we roll.

Roadside, we handle the fixes that get you moving: air leaks, brakes, batteries, starters, belts, coolant leaks, and derate troubleshooting. Bay-level jobs get scheduled at the shop, where the tools and lifts live.

DOT annual inspections

We do DOT annuals on your tractor and your trailer — each needs its own — in one visit. Inspections are performed by qualified inspectors per FMCSA 49 CFR 396.19, and we keep the reports for 14 months. Ask for the annual when you book any other work and we'll bundle the visit.

Driver questions

Are you a Kenworth or Peterbilt dealer?

No. We're an independent repair shop. We work on Kenworth and Peterbilt trucks every week, including PACCAR MX-13 and Cummins-powered units, but we're not an authorized dealer and don't claim to be.

Can you diagnose a derate on a PACCAR MX-13?

Yes. We read the codes, trace the cause — often in the aftertreatment system — and quote the repair before work starts. If the fix is beyond a road call, we'll get you into a Jerome bay.

Do you take walk-ins for Kenworth and Peterbilt work?

Yes, 7 AM to 10 PM every day at 2745 Tucker Ct Ste A in Jerome. Calling (208) 696-9888 first helps us line up parts so your truck spends less time in the bay.
