About Southern Diesel Repair
Southern Diesel Repair (SDR Dallas) is a full-service heavy-duty diesel truck, trailer, tire, and fleet repair company serving the Dallas–Fort Worth Metroplex and surrounding North Texas communities. With 24/7 mobile roadside service and full-service in-shop repair capabilities, SDR is focused on one mission: minimizing downtime and getting commercial vehicles safely back on the road as quickly as possible.
Our experienced technicians provide comprehensive diesel truck and engine diagnostics, mechanical repairs, preventive maintenance, and emergency roadside assistance for owner-operators, commercial fleets, trucking companies, buses, trailers, and other heavy-duty equipment. Whether a truck breaks down on the highway or requires scheduled maintenance, SDR provides the expertise and equipment needed to keep our customers moving.
Our services include diesel engine diagnostics and repair, brake systems and brake chambers, transmission and drivetrain repair, turbocharger service, suspension, steering and alignment, axles, wheel seals, cooling systems, radiators, electrical diagnostics, alternators, starters, fuel systems, injectors, hydraulic hoses, DEF and EGR systems, and DPF service. SDR also provides comprehensive commercial truck tire repair, replacement, roadside tire service, trailer repair, and trailer body repair.
When a breakdown happens away from the shop, SDR's 24/7 mobile diesel repair units can respond throughout the Dallas–Fort Worth area. Our roadside technicians handle engine problems, brake and air-system failures, tire issues, electrical problems, jump starts, battery service, fuel delivery, trailer repairs, and diagnostic troubleshooting. When a repair cannot be completed roadside, we can coordinate getting the vehicle to our shop for more extensive service.
For commercial fleets, SDR provides preventive maintenance programs, scheduled fleet service, DOT inspections, diagnostics, and multi-truck support designed to reduce unexpected breakdowns and costly downtime. We understand that when a commercial truck isn't moving, it isn't making money.
From a single owner-operator experiencing an emergency breakdown to companies managing large commercial fleets, Southern Diesel Repair provides dependable heavy-duty repair solutions 24 hours a day, seven days a week.
