Emissions, inspections, brakes, fluids, cleaning, general repairs, suspension, HVAC, and cooling-system work in one clear service list.
Truck & Trailer Repair
Complete truck and trailer repair for fleets and owner-operators. From air systems and lighting to brakes, suspension, and aftertreatment, power units and trailers are serviced under one roof — diagnostics, repair, and preventive maintenance in a single visit.

Emission Services
DPF, DOC, SCR, and EGR service for on-highway and off-highway vehicles and equipment. Regeneration problems, fault codes, and restricted aftertreatment are diagnosed with the right tooling, then cleaned, repaired, or replaced to keep engines compliant and on the road.

DPF Cleaning
Diagnostic-driven DPF cleaning for restricted or contaminated filters. Pressure checks and forced-regeneration testing confirm the fault first, then the DPF, DOC, SCR components, and EGR systems are cleaned or serviced so the system breathes again instead of hiding the problem.

DOT Inspections
Commercial vehicle and trailer inspections focused on safety-critical systems. Brakes, steering, suspension, lighting, and tires are checked against DOT requirements, defects are documented clearly, and repairs are quoted and completed so you return to the road with paperwork in order.
Learn more →
Brake Services
Brake and ABS inspection, troubleshooting, service, and repair for trucks and trailers. Slack adjusters, shoes and pads, drums, air valves, and ABS sensors are checked together so pulling, weak braking, or dash warnings are traced to the root cause — not just the symptom.

General Repairs
Everyday electrical, air-system, steering, and mechanical repairs that keep equipment working. Air leaks and airbags, lights and wiring, ABS faults, and steering complaints are diagnosed and fixed with quality parts — one shop for the repairs that keep fleets moving.

Diesel Force Cleaning
Focused diesel aftertreatment cleaning for restricted or contaminated components. Using the Diesel Force process, DPF and related components are cleaned, inspected, and tested rather than blindly replaced — restoring flow and performance at a fraction of replacement cost.

Fluid Changes
Routine oil, fluid, and filter service for commercial vehicles and equipment. Engine oil, transmission, differential, and coolant are serviced on fleet-friendly intervals, and every change is a chance to spot leaks, wear, and small problems before they become breakdowns.
Learn more →
Suspension Repairs
Suspension inspection and repair for ride, handling, and load-support concerns. Airbags, springs, shackles, bushings, and shocks are checked for wear and damage and ride height is verified — protecting tires, alignment, and driver comfort in one service.
Learn more →
HVAC Services
Heating and air-conditioning service for reliable cab comfort and defrost performance. Compressors, blowers, condensers, and HVAC electrical faults are diagnosed with proper gauges and tooling, so the A/C blows cold and the defroster clears the windshield when it matters.
Learn more →
Cooling Systems
Cooling-system inspection and repair for trucks and equipment operating under load. Radiators, hoses, water pumps, and fan clutches are leak-checked and serviced, and coolant is tested and replaced — protecting the engine from the overheating that ends trips early.
