WARRENVILLE, Ill. — Navistar has launched an online store for heavy-duty truck parts.

The truck and parts maker claims to be the first OEM to offer an e-commerce site for heavy-duty truck and bus parts.

The store, which went live today, is available at Partsmartparts.com. Orders are filled by the customer’s local International dealer, the company announced.

“Navistar is taking a leadership position in e-commerce for heavy duty truck and bus parts,” said Michael A. Cancelliere, senior vice-president and general manager for Navistar Parts in North America. “With a customer-friendly interface and the ability to order 24/7 online, our new Web site allows our dealers to extend their customer reach and makes it easier for customers to do business with us.”

The online store features a full product catalog and a user-friendly parts selection tool, the company says.

“This new approach will definitely appeal to today’s Internet-savvy customer,” said Nate Jolliff, director of parts operations integration for Navistar. “This is the customer who may not regularly patronize a dealership for service, but has the knowledge and ability to know what parts are needed and how to install them. We’re connecting the customer with their local International and IC Bus dealer through a seamless online ordering system.”
