What We Do

Services / Built Heavy

Every job calibrated to spec. Whether you're chasing a check-engine light or a horsepower number, we run diagnostics like a sniper — measure twice, fix once.

// 01

Diagnostics & Repair

Engine codes, electrical gremlins, drivability issues. We pull data, isolate the fault, and fix the actual problem — not a parts cannon.

// 02

Performance Tuning

Custom tunes, EGR & DPF deletes (off-road use), street and sled-pull builds. More torque, better mileage, dialed throttle response.

// 03

Turbo & Injectors

Turbo rebuilds, upgrades, and CP3/CP4 swaps. Injector pop-testing, balance rates, and high-flow nozzles for the builds that hit hard.

// 04

Fleet Maintenance

Scheduled PMs, DOT inspections, brake & drivetrain service. Keep your trucks earning instead of sitting. Priority scheduling for fleet accounts.

// 05

Lift Kits & Accessories

Suspension lifts, leveling kits, wheels, tires, bumpers, lights. We spec it, install it, and align it right so your build hauls and handles.

// 06

Don't See It Listed?

Powerstroke, Cummins, Duramax — if it burns diesel, we've probably wrenched on it. Call us with what you're chasing. Honest answer, fair quote.

The Shop · The Story

Built by a Welder Mechanic.
Run on Honesty.

Caliber Diesel is new — months new — but the hands behind it aren't. Owner-operator Gage spent years as a welder mechanic on some of the largest diesel rigs on the planet, deep in the Texas mining industry. Before that, pipeline welding and fab work. The kind of jobs where "good enough" isn't.

Now he's brought that same standard to a local shop — with a pricing model most places won't touch.

The Caliber Promise

You Buy the Parts. We Charge for Labor.

That's it. No hidden markup, no padded invoice, no parts-cannon racket. Gage tells you exactly what your truck needs and where to buy it. You pay the supplier directly. We turn the wrenches. Honest work, fair price, every time.

01

Diagnosis First

Real scan, real road test, real answer. We isolate the fault before quoting a fix — no guess-and-replace.

02

You Own the Parts

Gage advises on exact part numbers and trusted suppliers. You purchase direct. No markup, no middleman.

03

Labor, Quoted Up Front

Flat-rate or hourly, you'll know the labor charge before we start. No surprises at pickup.

04

Fabrication on Site

Welder by trade. If it needs to be built, repaired, or reinforced, it gets done here — not farmed out.
