Broke down on the job? Running before your next shift.

OPERATIONS

What rolls through the door

OP-01

Diesel repair & diagnostics

The house specialty. Work trucks, EcoDiesels, Cummins, Power Stroke, Duramax: driveability, fuel systems, turbos, and the electrical gremlins other shops send away.

"We're here on a Sunday wrapping the week up." — the shop's own Facebook, on an EcoDiesel
OP-02

Gas repair & tuning

Full mechanical repair on gas engines plus HP Tuners work, from daily drivers to the fun stuff. The crew came up on Hellcats and Hemis; your Camry is safe too.

OP-03

Transmissions & drivetrain

Factory Mopar reman units in the crate, installed with a dealership-grade process, 68RFE and friends. Rebuild-or-replace advice given straight, not upsold.

"Factory Mopar reman units getting dropped off today." — shop Facebook
OP-04

Heavy equipment

Skid steers, tractors, generators, and whatever else your operation runs on. Trailer pickup and drop-off available anywhere from Mansfield to Ennis.

"We don't discriminate, we work on all sizes." — shop Facebook
OP-05

Maintenance & keys

Oil services, brakes, batteries and filters stocked on consignment, plus key cutting for fleet accounts. The boring stuff, done fast so trucks keep earning.

OP-06

Pickup & delivery

Can't leave the job? We'll come hook up the trailer. Equipment transport runs a flat $200 inside our service loop, and customer cars get dropped back when we can.

PARTS PROGRAM — SPEC W-01

Genuine Dodge parts. Three-year dealership warranty. Independent prices.

Fourteen years inside Mopar buys relationships a startup can't. We source factory parts below wholesale straight from the Dallas hub, and every one carries a three-year warranty the dealership network has to honor. Dealer parts, dealer warranty, without the dealer invoice.

THE STORY

Built the hard way

Oil-change kid to service manager.
Then he bet on himself.

Eddie started turning wrenches in a Mopar service lane in 2011 and worked every rung: engine tech, diesel tech, shop foreman, service manager. At his last stop he took a store from $220K a month to $680K, on pace past a million and a half a year, by growing his techs three to five percent at a time instead of burning them out.

When ownership demanded the burnout math instead, he shook hands and walked. No plan. A storage unit, one helper, and a phone that would not stop ringing. Ten trucks showed up the first week. By summer it was a 3,200 square foot shop with a lot so full the landlord comes by to count the cars.

That's the whole pitch, really: the man runs the shop the way he refused to run someone else's, and the parking lot is the proof.

"Busy is an understatement." — EDDIE, OWNER, WHEN ASKED HOW BUSINESS IS
