A check-engine light is a symptom, not a diagnosis. We pull the codes, then we actually test the circuit, sensor, or component the code points at — so you pay to fix the problem once instead of replacing parts until the light goes out.
Diesel work is its own trade. Injection pressure, aftertreatment, turbos, and glow systems all behave differently than a gas engine, and a shop that only sees one diesel a month will guess. We see them every day.

Tires are the only part of your truck that touches the road, and the right set depends on what you actually do with it. We'll tell you honestly whether you need a new set or whether the one you're worried about can be safely repaired.
A vehicle that pulls or wanders is eating a set of tires while you drive it. We measure camber, caster, and toe against factory spec — and on lifted trucks, against what the lift actually requires.
We measure pad thickness and rotor runout and show you the numbers. If you have 40% left, we'll tell you to come back later — we would rather see you again in six months than sell you brakes you didn't need.
The cheapest repair is the one you never need. Every oil change here includes a real multi-point inspection — fluids, belts, brakes, tires, and a look underneath — so small problems get caught while they are still small.
Conventional, synthetic blend & full synthetic oil
New tires for cars, trucks, SUVs and duallies, in all-terrain, mud-terrain and highway tread. Every set is mounted, road-force balanced and gets a TPMS reset, and we check tread depth when we rotate. Trailer and heavy-duty light-truck tires are on the menu too. We’ll tell you honestly whether you need a new set or whether the one you’re worried about can still go.
A tire that keeps going low, tread wearing unevenly, or a vibration that changes with speed all deserve a proper look. We fix flats with an interior patch-plug and check the tread and wear pattern while the wheel is off. If a tire can’t be safely repaired, we’ll tell you so plainly and walk you through the options before any new rubber goes on.
Daily drivers, work trucks and heavy-duty diesel pickups are worked on in the same bays, so one shop handles the whole truck. From Power Stroke, Cummins and Duramax engines to brakes, tires and lifted-truck alignment, it gets done in one visit. A truck that pulls, wanders, makes a new noise or shows a check-engine light should come in before a small issue grows.
Diesel work is its own trade. Injection pressure, aftertreatment, turbos and glow systems behave differently from a gas engine, and we see them every day. We diagnose injectors, fuel pumps and high-pressure fuel systems, turbochargers, DPF and EGR faults, and hard-start or no-start problems on Ford Power Stroke, Ram Cummins and GM Duramax trucks.
Four steps from “something’s wrong” to back on the road
01
Tell us what it's doing
Call, book online, or drop it off. Describe the symptom in your own words — you don't need to know the part name.
02
We diagnose it properly
Codes, live data, and hands-on testing. We find the cause, not just the code, and we document what we find.
03
You get the estimate first
A written quote with what's urgent, what can wait, and what it costs. Nothing gets repaired until you say go.
04
Fixed right, ready to roll
Quality parts, road-tested before pickup, and a clear explanation of what we did and why.

What Cedar Hill Says
Word of mouth is how a shop like ours stays open
“Just had an oil cooling leak. The switched out everything new within under an hour 1/2. Customer service was great. It’s hard to find good mechanics. I’m glad I found some here. Check em out.”

“These guys here provide excellent services. I came here with a window problem and found out people who did my window years ago never fix the problem.”
Walk-ins are welcome for tires, oil changes, and quick checks. For diagnostics, diesel work, and anything that will take a bay for a while, an appointment gets you in and out much faster.
Do you work on diesel trucks?
Yes — Ford Power Stroke, Ram Cummins, and GM Duramax are core work for us, from routine service to injectors, turbos, and aftertreatment diagnostics.
Will you tell me what it costs before you start?
Always. You get a written estimate before any repair begins, and we call you before doing anything that wasn't on the original approval.
Can you align a lifted truck?
Yes. Lifted and leveled trucks need different specs than stock, and we align to what the suspension actually requires — not just the factory number.
Do you sell tires, or only repair them?
Both. We sell and install new tires — all-terrain, mud-terrain, highway, and heavy-duty light-truck — and we repair flats properly with an interior patch-plug when the damage allows it.
What areas do you serve?
We're on 110 N Clark Rd in Cedar Hill and regularly serve Cedar Hill, Duncanville, DeSoto, Midlothian, Grand Prairie, Lancaster, and the surrounding southwest Dallas County area.
