WHO WE ARE
UPTIME PARTS: YOUR TRUSTED PARTNER

A true partner is someone that you can count on. Someone who cares about your success. Someone who delivers something valuable - day-in and day-out. At UpTime Parts, that's what we strive to be to our customers.

We're a national aftermarket parts supplier for light-duty trucks. We're a wholly owned subsidiary of Navistar, Inc. With our truck expertise, capabilities for almost any make/model, custom kitting services, innovative parts return program and more, UpTime is a unique single-source option to support your fleet more efficiently and effectively.

Our goal is simple. We want to be much more than a parts provider. We want to be a partner - your partner.
