TOP GUN HD provides fleet maintenance services for heavy-duty on-road trucks and trailers, including tractors, tankers, and vocational units. Our team supports scheduled maintenance, roadside support, and compliance-focused servicing such as CVIP inspections and brake system maintenance.
On-road fleet maintenance focuses on:
Mobile service allows us to perform maintenance at your yard or job location, minimizing lost time from transporting units off site.
Off-road equipment operates under different conditions and requires a different maintenance approach.
We provide fleet maintenance services for heavy-duty equipment used in mining, oil and gas, pipeline, forestry, and civil construction environments. This includes excavators, dozers, loaders, haul units, and other industrial equipment.
Off-road equipment maintenance focuses on:
Our technicians understand how equipment is used in the field and perform maintenance that reflects real operating conditions, not generic schedules.
Unplanned downtime is expensive. Preventative maintenance is one of the most effective ways to reduce breakdowns, control operating costs, and keep equipment in service. TOP GUN HD delivers preventative and mobile maintenance services tailored to your operation, usage patterns, and operating environment. With fully equipped service trucks, we perform inspections and servicing directly at your facility or job site, helping identify issues early and complete maintenance without pulling units out of rotation. The result is fewer emergency callouts, better reliability, improved safety, and more predictable maintenance planning.
