TORQUE
The Shop FleetManagers ActuallyTrust.
Cummins ISX teardowns. Detroit DD15 injector sets. DPF deletes filed right. If it runs diesel and it's down, we have the tooling, the software, and the spec sheets to bring it back.
Fault code P0087 — Fuel Rail Pressure Low
OEM Cummins INSITE™ active
We scan before we
touch anything.
Every rig gets a full OBD-II pull with OEM-licensed software — Cummins INSITE, Detroit Diagnostic Link, or Cat ET depending on what's on the lift. We're reading live PIDs, not just fault codes.
The diagnostic report goes to you before we write a repair order. You know what's wrong, what it'll cost, and how long it'll take. No surprises on the invoice.
"They handed me a 14-page diagnostic printout before asking me to sign anything. I've never seen that from a shop."
— Marcus Webb, Owner-Operator · Peterbilt 389 / ISX15
Down to the crank.
Every spec verified.
When the head comes off, we mic the bores, check the crank journals, and pressure-test the block. If a measurement is outside factory spec, we document it and call you — we don't make that decision for you.
Parts sourcing is OEM or equivalent-spec aftermarket only. We're not chasing price on injectors or turbo cartridges. Cheap parts come back. We'd rather you not.
"Torque sourced genuine Cummins injectors, not aftermarket knock-offs. The truck has run 180,000 miles since. Zero issues."
— Diane Kowalczyk, Fleet Manager · 40-truck Cummins fleet, Chicago IL

Torqued to spec.
Dyno-proven.
Every fastener gets a calibrated torque wrench and a second pass. Head bolts follow the OEM sequence — no guessing, no shortcut. The torque sequence sheet lives in the job file permanently.
Before the truck leaves, it goes on the engine dyno. We're verifying power output, checking for smoke, and confirming fuel trim is within spec. You get the dyno sheet with your invoice.

Services
We don't do oil changes. We do the work other shops turn away — the complicated teardowns, the difficult diagnostics, the jobs that need to be right the first time.
Turbo Rebuilds
Full cartridge replacement, bearing inspection, compressor and turbine wheel balancing. BorgWarner and Holset units rebuilt in-house. We don't send turbochargers out.
Injector Diagnostics & Replacement
Individual injector flow-testing on our Hartridge bench. We identify the bad cylinder, not the bad guess. Genuine Cummins XPI and Detroit HPCR units only.
DPF Deletes & EGR Work
Off-road and competition use only. Filed with the appropriate documentation. Full EGR cooler replacement also available — we see a lot of cracked coolers on high-mileage ISX15s.
Full-Frame Inspections
Pre-purchase inspections, pre-DOT inspections, and post-accident assessments. We put the rig on the lift, check every cross-member, and give you a written report with photos.
