Your engine is the most expensive component on your truck, and when it starts losing power, smoking, or throwing codes, every mile gets riskier. I-55 Truck & Trailer Repair provides diesel engine repair and maintenance for semi-trucks and heavy-duty vehicles at our shop on I-55 in Crawfordsville AR. Drivers and fleets across Memphis & West Memphis rely on us to find engine problems early and fix them before they turn into a full rebuild.

Why Choose Us
Modern diesel engines combine heavy mechanical parts with complex electronics, and a wrong diagnosis can get expensive fast. Our ASE certified mechanics use advanced diagnostic tools alongside hands-on inspection to find the true source of a problem. We work on the major engine platforms found in today's trucks and explain every recommended repair in plain language. The goal is simple: restore power, reliability, and fuel efficiency without replacing parts you don't need.
What We Offer
Most engine failures start with small warning signs like rough idling, extra smoke, or a slight drop in fuel mileage. We handle everything from routine maintenance that prevents those problems to repairs that fix them fast. Here's what our diesel engine service includes:

Engine Diagnostics: We scan the engine's computer and run hands-on tests to identify the root cause of performance issues. Accurate diagnosis saves you time and prevents unnecessary repairs.
Loss of Power Repair: Low power can come from fuel, air, exhaust, or sensor problems. We track down the cause and restore the pulling power your truck needs under load.
Fuel Injector Service: Worn or leaking injectors waste fuel, cause smoke, and can damage the engine over time. We test, clean, and replace injectors to restore smooth, efficient combustion.
Turbocharger Repair: A failing turbo can cause whistling, smoke, and a big drop in performance. We inspect, repair, or replace turbochargers and check the related air intake components.
Oil Leak and Gasket Repair: Leaking seals and gaskets can lead to low oil levels and engine damage. We locate the source and replace worn gaskets to stop the leak for good.
Valve Adjustments and Overhead Service: Proper valve lash keeps your engine running smoothly and efficiently. We adjust valves and service overhead components according to manufacturer intervals.
EGR System Repair: Clogged EGR valves and coolers can cause rough running, soot buildup, and warning lights. We clean or replace EGR components to keep your engine and aftertreatment healthy.
Preventive Engine Maintenance: Regular oil changes, filter replacements, and inspections are the best protection for your engine. We keep your truck on a maintenance schedule that helps it reach its full lifespan.
Watch for loss of power, excessive smoke, hard starting, rough idling, unusual knocking, rising oil consumption, and a check engine light. Any of these is a good reason to have the engine inspected.
Black smoke usually points to a fuel or air intake problem, white smoke can mean coolant or unburned fuel, and blue smoke often signals oil burning. Each needs a proper diagnosis to confirm the cause.
We service the major diesel engine platforms used in commercial trucks. Call (870) 635-4003 with your engine make and model, and we'll confirm we can help.
If the engine has major internal damage, low compression, or excessive wear across multiple components, a rebuild may be more cost-effective than ongoing repairs. We'll walk you through both options after diagnosis.
Service intervals depend on the engine, oil type, and how the truck is used. We follow manufacturer recommendations and can set up a custom schedule for your truck or fleet.
Expert repairs for every major system on your truck, in the shop or on the road.

Our mobile mechanics bring the repair to your truck, whether you're on the roadside, at a truck stop, or in your yard. We handle tires, batteries, forced regens, and routine fleet servicing on-site, 24 hours a day.


We repair and rebuild diesel engines, transmissions, clutches, cooling systems, and drivelines. From minor fixes to full overhauls, our ASE certified mechanics restore power and reliability.

Advanced diagnostic tools help us find problems fast, from check engine lights to faulty modules. We also repair EGR, DPF, and emission control systems to keep your truck running clean and compliant.


Safe stopping starts with a healthy brake system. We inspect, maintain, and repair air brakes, ABS, parking brakes, and brake fluid systems to keep you safe and DOT ready.

We repair, replace, rotate, and balance truck tires, and service suspension parts including shocks, bushings, bearings, and joints. The result is a smoother ride, even tire wear, and longer component life.


Beyond everyday repairs, we handle axle work, truck HVAC systems, and custom welding and fabrication for trucks and trailers. Our preventive maintenance and scheduled fleet programs help you catch problems early and avoid costly breakdowns.
