If It Hauls, We Handle It.
Semi Truck Repair
When your semi is down, every hour costs money. 1776 handles heavy-duty diesel diagnostics, brakes, driveline, electrical, and the body work most truck shops won't touch, all under one roof in Sioux Falls.
Heavy-Duty Diesel
1776 is built for diesel work. From Cummins and Detroit to PACCAR and Duramax, we diagnose hard problems, fix them right, and get working trucks back on the road.
Diesel Diagnostics
Codes don't fix trucks, techs do. We chase the actual problem instead of throwing parts at it until something works.
Engine Repair
From injector replacement to in-frame overhauls, 1776 handles the big jobs that keep working trucks earning.
Transmission & Clutch
Slipping clutch? Shifting like a wagon? Driveline shaking the fillings loose? We figure out what's actually wrong and fix it.
Brake Repair
Brakes are not the place to cut corners. We service air systems, foundation brakes, and trailer brakes to DOT standards.
Suspension & Steering
A truck that wanders, dog-tracks, or eats tires has a fixable problem. We diagnose the cause and repair it right.
DOT Inspections
Stay road-legal. We provide honest inspections and clear repair recommendations so your equipment passes the first time. [Add DOT inspection authorization here if applicable]
Fleet Maintenance
Built for fleets of 1–10 trucks: owner-operators, contractors, local delivery, ag operators, and service companies. We help you plan PMs, catch problems early, and reduce downtime.
Commercial Truck Body Repair
Passenger-car body shops are not always built for working trucks. 1776 handles commercial truck body repair, panel work, paint, and structural concerns on equipment that has to earn.
Semi Truck Collision
Wrecked your hood, cab, or sleeper? We'll work through the photos, the estimate, and the insurance side so you know your options.
Trailer Repair
Dry vans, flatbeds, reefers, hoppers, and step decks, we repair the parts that break and weld the parts that crack.
Welding & Fabrication
From cracked frame rails to custom brackets and complete flatbed builds, our welders do the work that keeps working trucks earning.
Custom Truck Builds
1776 is not just a repair shop. We build custom trucks, restore classics, and upfit work trucks for the way you actually use them.
Built for the guys who actually drive 'em.
Dealers run on warranty time. Car shops don't know a kingpin from a king cab. We do this, heavy-duty, every day, on rigs that have to be back hauling tomorrow.
You'll get a diagnosis, a number, and a timeline. You'll get updates. You'll get your truck back. That's it. That's the deal.
A real guy answers
No service writer, no call center. You talk to someone who's been under a truck today.
Estimate before we lift a wrench
Written number, clear scope. No surprises on the invoice.
You approve the work
Nothing happens to your rig until you say go. Period.
One shop. One bill.
Engine, body, trailer, fab, all under our roof. Stop chasing four shops.
Owner-operators welcome
We work with one-truck guys the same as we work with twenty-truck fleets.
Updates, not silence
Texts, photos, straight talk on timing. You're not in the dark.
Your trucks roll. Your bills don't pile up.
Five trucks or fifty, we'll set the PM intervals, run the DOTs, catch the brakes before they catch you, and keep one number on speed dial. Predictable schedule. Predictable invoice.

Crunched? Smashed? Snap a picture.
Smashed cab, peeled fender, jacked-up frame, trailer punched, text us photos, we'll come back with a real number. We talk to the adjuster, you keep working.
Got a build in your head? Bring it in.
Headache racks. Flatbeds. Service-body upfits. Stack kits. Bumper rebuilds. Old farm truck that needs to ride again. If you can sketch it on a napkin, we can build it in steel.
Real trucks. Real drivers. Real fixes.
Three shops swore my regen was fine. These guys found the bad sensor in an hour and I haven't seen a code since.
PM schedule, one invoice, photos every time. Our downtime is cut in half and I actually sleep at night.
Backed my service truck into a dumpster on a Monday. Estimate by Tuesday, back on the job by Friday.
Welded a cracked trailer cross-member that two other shops wouldn't touch. Held up through a full winter.
