Engine Diagnostics and Repairs

The heart of any Kenworth truck is its powerful engine. We provide comprehensive engine diagnostics and repair services, utilizing the latest tools to assess and address any issues. From the PACCAR engines known for their superior performance and fuel efficiency to Cummins systems that offer reliability, we maintain your engine's longevity and power.

Transmission Excellence

Kenworth's transmissions are engineered for smooth shifting and reliable operation under heavy loads. Our maintenance services include detailed inspections and repairs of manual and automatic transmissions. We handle complex systems like the Eaton Fuller transmissions, ensuring your gears shift seamlessly with minimal downtime.

Suspension and Steering Systems

A Kenworth truck's suspension and steering systems are vital for driver comfort and load stability. Our services include thorough checks and repairs of air suspensions, shock absorbers, and power steering components. We ensure your truck handles as expected, providing a safe and controlled driving experience.

Brake System Overhauls

Safety is non-negotiable, and Kenworth's robust brake systems are integral to your truck's safety. We offer complete brake service, including air brake inspections, drum/disc repairs, and ABS diagnostics. Our team ensures that your truck responds precisely and reliably when you press the brake pedal.

Electrical System Maintenance

In a Kenworth, the electrical system is the nerve center, controlling everything from the dashboard to the lighting systems. Our electrical system maintenance covers battery checks, alternator repairs, and wiring inspections, preventing potential electrical failures that could sideline your truck.

HVAC System Care

The HVAC system in your Kenworth truck provides comfort throughout the seasons. We offer HVAC servicing, including coolant refills, compressor repairs, and air quality checks to ensure your cabin remains a haven, regardless of outside temperatures.

Preventive Maintenance: The Key to Longevity

We believe in proactive care. Our preventive maintenance programs are designed to catch potential issues before they become major problems, saving you time and money. Regular service intervals tailored to your Kenworth's specifications mean that every component is inspected and maintained to prevent unexpected breakdowns.
