Dedicated Fleet Support & Engineering Partnership

Fleet clients receive structured service coordination, consistent repair standards, and engineering oversight. We operate as a maintenance partner—not a transactional repair shop.

The Fleet Advantage

Mobile Engineering Service (We Come to You)

Downtime is not limited to breakdowns — travel time is lost productivity. Our mobile service brings engineer-led diesel expertise directly to your operation, allowing fleet vehicles to be serviced where they operate.

We deploy fully equipped mobile units staffed by professional engineers, capable of performing diagnostics, repairs, and maintenance on-site. This eliminates unnecessary vehicle movement, reduces scheduling disruptions, and keeps assets in service longer.

Designed for Fleet Efficiency

Our mobile engineering service is ideal for:

  • Fleet yards and distribution centers
  • Scheduled preventive maintenance
  • Diagnostics and electrical troubleshooting
  • Brake, cooling, and fuel system repairs
  • Emissions and compliance-related service
     

Engineering Oversight in the Field

Unlike traditional mobile repair, our engineers apply the same OEM-aligned standards, diagnostic depth, and documentation on-site as we do in our facilities. Field service is executed with the same level of precision and accountability.

Mobile Service, Without Compromise

This is not emergency-only roadside repair. It is strategic, engineering-driven mobile service designed for established fleets that value uptime, efficiency, and technical accountability.


  • Reduced downtime and travel delays
  • Increased vehicle availability
  • Faster diagnostics and decision-making
  • On-site service without compromising quality
  • Predictable scheduling for large fleets

Mechanical Engineering Solutions for Your Fleet

Fleet Brake Systems & Safety Compliance

We provide complete air brake system service engineered to meet fleet safety standards, regulatory requirements, and performance consistency across vehicle groups. Our engineers diagnose wear patterns, system inefficiencies, and failure risks to ensure reliable stopping power and reduced safety exposure.

Advanced Diagnostics & Electrical Systems

Modern fleets operate on electronically integrated platforms. Our engineers utilize OEM-level diagnostic tools and system-based analysis to identify electrical faults, communication failures, and sensor issues with precision - reducing troubleshooting time and eliminating repeat failures.

Transmission & Drivetrain Engineering

We service manual and automated transmissions, differentials, and driveline systems with a focus on durability and operational efficiency. Our engineering approach ensures proper calibration, load management, and long-term drivetrain reliability under high-duty fleet conditions.

Engine Rebuilds & Life-Cycle Extension

Our engine rebuild and overhaul services are engineered to extend asset life, control capital expenditures, and improve return on investment. Each rebuild follows OEM specifications, engineering tolerances, and documented quality controls.

Preventive Maintenance & Asset Optimization

Preventive Maintenance & Asset Optimization

We design preventive maintenance programs aligned with duty cycles, mileage, and operational demands. These programs reduce unplanned downtime, stabilize maintenance costs, and improve fleet availability.

Emissions / Aftertreatment Compliance

Preventive Maintenance & Asset Optimization

We provide advanced diagnostics and repair of DPF, DEF, SCR, and EGR systems to maintain emissions compliance while minimizing regeneration issues and operational disruptions.

Fuel & Thermal Management Systems

DOT Inspections & Regulatory Support

Suspension, Steering & Ride Control

Our engineers service fuel delivery and cooling systems to prevent performance degradation, overheating events, and efficiency loss—critical for high-utilization fleet vehicles.

Suspension, Steering & Ride Control

DOT Inspections & Regulatory Support

Suspension, Steering & Ride Control

We service suspension and steering systems to improve vehicle stability, reduce component fatigue, and enhance driver comfort—supporting safety and long-term fleet durability.
