Our bays are in Florence on Mitchell Ct. Powerstroke, Cummins, Duramax, Isuzu and Cat work — diagnostics through full rebuilds.
Florence has a lot of diesel owners. Work pickups for the county and the corrections facilities, farm trucks west of town, service trucks headed to Casa Grande and the East Valley, and fleet vehicles running on AZ-79 and AZ-287 every day. Our shop sits on Mitchell Ct on the north side of town — minutes from most Florence neighborhoods and right off the main corridor south.
What we work on in-house: Powerstroke 6.0 / 6.4 / 6.7 / 7.3 (old and new), Cummins 5.9 / 6.7 / L9, Duramax from LB7 through L5P, Isuzu 4HK1 / 6HK1 and NPR box trucks, and Cat C7 / C9 / 3126 / 3306 for the heavier stuff. Injectors, HPOP, CP3/CP4 pumps, turbos and VGT actuators, EGR, DEF/DPF, cooling, head gaskets, timing, full rebuilds — including the chassis and trans work that diesel trucks also need.
Florence heat eats diesels in specific ways. Fuel pumps and CP4s don't love 115°F. Short in-town trips never finish regens, so DPFs clog. Dust kills MAF sensors and air filters faster than anyone expects. 6.0 Powerstrokes develop EGR cooler and head gasket issues faster here than in cooler climates. These aren't surprises — we see them every week, and we know which parts actually fix them.
We also stay in our lane: no DPF/DEF/EGR deletes (illegal on street vehicles), no over-the-road Class 8 long-haul tractors. Light-duty and medium-duty diesel is our wheelhouse, and if a job is outside that, we'll tell you.
Rough idle and misfires on 6.0 Powerstrokes (usually injectors or STC fitting), crank-no-start on Cummins (lift pump, FCA, or FASS-style upgrade), active regen stuck in a loop (DPF pressure sensor or EGR cooler), check-engine light with a glow-plug code (easy win), and trucks that just won't make rated power anymore (usually VGT turbo or fuel delivery).

Diesel trucks need the same brakes, trans, electrical and chassis work every other vehicle does. We do all of it. See the full list.
Powerstroke, Cummins, Duramax, Isuzu, Cat — any diesel, any size.
Scheduled PMs, DOT inspections, dispatchable repairs.
Service, repair, replacement — automatic and manual.
Pads, rotors, lines, shocks, struts, alignment-ready work.
Check-engine codes, driveability issues, hard-to-find gremlins.
Batteries, alternators, starters, wiring, parasitic draw.
Not a body shop. We don't do collision work, paint, body panels, interior upholstery, or child-seat installations — those take different tools and the right specialist. Need one of those? Ask when you call and we'll point you to someone good.
Get it scanned before it gets worse. Injectors aren't cheap; diagnosis is.
Schedule a ServiceYes — regularly. Bulletproofing (EGR cooler, oil cooler, head studs, FICM), injector replacement, STC fittings, high-pressure oil leaks, and full rebuilds. We're honest about what's worth doing on a 6.0 and what isn't.
We service CP4s per factory procedure. For CP3 conversions on later Duramax and Cummins platforms, call us — availability depends on the parts kit and emissions configuration.
No — illegal on street-driven vehicles under federal and AZ law. We repair emissions systems rather than remove them.
Yes. PMs, DOT prep, repair scheduling. Call and ask for fleet service.
