Preventative Maintenance

Downtime service can often be prevented with regularly-scheduled preventative maintenance.

Fluids, filters, wipers, hoses, tire pressure. Let USA manage your maintenance schedules. You can arrange for weekly, monthly, quarterly or annual upkeep. Our price includes new parts and fluids as well as haul away and disposal.

Fleet Monitoring

Terminal Tractors are designed and built for years of tough work under harsh conditions.

But that doesn’t mean they deserve to be abused or neglected.

With the help of Telematics, United Service Alliance can keep you apprised of how your unites are holding up, from monitoring engine hours and identifying engine faults to alerting you to maintenance and/or service needs – before the issue become critical. In addition, Telematics can show you GPS positioning of your units and notify you of unsafe driving practices or driver abuse.

You can’t be everywhere, all the time, but Telematics can. Contact us for more information on keeping a watchful eye on your fleet.

Parts Sales

Terminal Tractors are vital to the efficiency of your day-to-day operations, so it’s important to protect that investment with high-quality replacement parts.

As an authorized Capacity Dealer, we can offer OEM Capacity parts, as well as OEM Allison and OEM Cummins parts.

If you’re not sure what part you need, let our Parts Representatives help you figure it out. We can either have our service team deliver your parts during call-outs, or drop-ship them directly to your door. Next day shipping is available, but for Texas, Oklahoma, Arkansas and Louisiana, typical delivery is 1-2 business days
