Custom Diesel Builds in Midland, TX

One-off diesel builds at Chris’s Diesel Service in Midland, for customers who know what they want. A custom build is not one service, it is several running in sequence over months, and what separates a finished truck from an abandoned project is how that sequence gets managed. Bring the spec or bring the goal. You get a written plan, staged pricing, and one shop with its name on the result.

Custom Builds Die From Drift. Not Difficulty.

The mechanical work on a custom build is the part we are least worried about. Every capability it draws on already runs here every week. What kills these projects is scope creep, silent months, and four vendors each blaming the other three. This is how we prevent that.

The Written Plan
  • Destination agreed before any money moves
  • Every stage itemized with its own number
  • Trade-offs named at the table, not discovered later
  • An honest no if the goal and the budget do not meet
Stages and Updates
  • The project broken into stages you can see finish
  • Photos and progress as each stage completes
  • Realistic timelines, including parts lead times
  • A call when something slips, not silence
Change Control
  • Every change request priced when it comes up
  • Nothing absorbed quietly into the final bill
  • Teardown surprises documented with photos first
  • You approve the new number before we continue
One Accountable Shop
  • No trailer rides between four different vendors
  • Cross-system problems are still our problem
  • One invoice, one schedule, one name on the result
  • A documented spec book hands over with the truck

Spec. Build. Deliver.

Custom projects die from scope drift and vendor ping-pong. Ours run on a written spec and one accountable shop.

    The Conversation

    Bring the spec or bring the goal. We turn it into a written build plan with honest numbers, realistic timelines, and the trade-offs on the table before money moves.

  2. 02

    The Build

    The engine build, fuel and tuning, drivetrain, and finish work sequenced under one roof. You get updates as stages complete, and change requests get priced honestly, not absorbed into surprises.

  3. 03

    The Delivery

    Shakedown miles, systems verified under load, and a documented spec book with the truck. Test-driven and signed off by Chris before you take it home.

Why One Roof Wins.

Most custom builds bounce between an engine shop, a trans shop, a fab guy, and a painter, and every handoff loses money and accountability. Here the whole build lives in one 140 x 150 ft shop in Midland with one name on it, serving customers across Odessa and the Permian Basin.

  • No Vendor Ping-Pong Engine, drivetrain, welding and fabrication, paint, and body under one roof. When something crosses systems, it is still our job.
  • Honest Quoting The build plan is written and priced before work starts. If your goal and budget do not meet, we say so at the table, not at invoice time.
  • Built to Be Driven Custom does not mean fragile. Builds leave here ready for real miles, verified under load, not trailered around problems.
  • The Right Customers We do not do fast work. We do right work. Custom builds are for owners who understand the difference and want it done once.

Common Questions

What counts as a custom diesel build?
Any project built to your specification rather than a package: a tow rig engineered end to end, a truck rebuilt around a specific power goal, or a one-off combination nobody sells. The test is whether it spans several disciplines over months rather than being one job with a start and a finish. If you can describe the destination, we can write the plan.
What is in the written build plan?
The destination in plain language, the work broken into stages, an itemized number against each stage, the parts and lead times we know about, and the trade-offs we have already identified. You see the whole shape of the project and its cost before you commit to the first stage rather than discovering it a year in.
Do I need to know exactly what parts I want?
No. Some customers arrive with a full spec sheet, others with a goal like a number, a trailer weight, or a truck they want transformed. Either works. We translate goals into hardware, and if you bring a spec with a weak link in it, we will point it out before we build it.
What happens when the scope changes mid-project?
It gets priced when it comes up and you approve the new number before we continue. Teardown reveals things on every long project, and hidden rust or a failed component you did not know about goes in front of you with photos rather than into the final invoice quietly. Scope changes are normal. Discovering them at the end is not.
Can a custom build include paint and restoration?
Yes. The professional paint crew and body shop are in the same building, so the mechanical build and the finish work get sequenced together instead of fought between two shops. If the project is primarily about bringing an older truck back, our truck restoration page covers that path in more detail.
How long does a custom build take, and what does it cost?
Months, and the spec sets the price, which is why the conversation comes first. Timeline depends on scope, machine work, and parts lead times, and you get a realistic staged schedule in the written plan plus updates as stages complete. We do not promise dates we cannot keep to win the job. Call (432) 557-6500 and tell us where you want to end up.
