Air brake service, chambers, slack adjusters, drums, rotors, wheel seals with documented torque so city stops stay controlled.
On-site PM days with inspection reports and fluid service tuned to urban stress to cut unplanned downtime.
Alternators, starters, belts, hoses, batteries, cooling diagnostics, reefer alarms handled on the curb, at the dock, or in the yard so perishables stay protected.
Mobile mounting, balancing, rotations, torque checks, roadside tire replacement to avoid delays on city blocks and highway merges.

Stop-and-go, heat, idling, and curbs wear down critical systems. We design PM plans to your exact routes. Expect fluid checks, brake measurements, steering play checks, battery load tests, aftertreatment health reviews, and tire wear tracking. Reports are digital and attach by VIN so you can plan parts and labor.
We equip drivers on warning signs like frequent regens, spongy brakes, flickering lights, hot smells, belt noise, steering pull, vibration. Calling early prevents costly emergencies. It keeps freight honest.
Proof is standard: visuals plus numbers for audit trails. Pricing is straight: clear labor, clear parts, zero upsell pressure. If we spot a future failure, we note it for planning so you choose timing.
Your reputation matters: clean uniforms, tidy work areas, respectful communication. Drivers feel supported. Loads stay on promise. This is the rhythm of reliable support.
Specialty urban rigs and heavy vocational trucks take abuse every block. We focus on the stress points city loads punish to stop vibration from turning into breakdown. When early warning signs appear, you get photo proof and a recommendation so you control downtime instead of reacting.
Electrical and cooling systems suffer in traffic. We remove electrical guesswork. We validate that cooling holds under stress. This prevents derates, protects aftertreatment, and keeps engines healthy.
