Deep Detail for Heavy Urban Duty

Specialty urban rigs and heavy vocational trucks face tight turns, weight, and constant braking.

If we see heat marks, cracks, or fluid traces, we send visuals and options so you choose timing without losing a day.

Idling and heat strain power and cooling. We load-test batteries, clean terminals, validate grounds, and check voltage drop under accessory load. We validate that cooling holds under stress. This prevents derates, protects aftertreatment, and keeps engines healthy.
