International Truck has launched the Diamond Partner Program to connect truck equipment manufactures with International dealers, providing them with benefits aimed at streamlining installation efforts.
The Diamond Partner Program is also designed to improve communication between upfitters and dealers, offer body builder resources, provide spec optimization and build stronger relationships.
“We believe that driving collaboration between the dealer and the truck equipment manufacturer is how you succeed in the vocational truck business,” said Mark Stasell, vice president, vocational truck, Navistar. “The Diamond Partner Program encourages these interactions in a way that completely changes the way that we and our dealers work with truck equipment manufacturers.”
Companies that are part of the Diamond Partner Program receive a number of perks including process, commercial and technical benefits. These benefits include:
Application Engineer: When a company signs up for the Diamond Partner Program, they are given an assigned application engineer who is responsible for their account.
Spec Review: International will send a cross functional team to review the company’s chassis specifications to evaluate order content and make recommendations that could remove cost, improve delivery time, and optimize vehicles.
Joint Customer Events: A Diamond Partner is offered the opportunity to host mutual customers for a VIP customer tour of Navistar’s World Headquarters in Lisle, Illinois, and a potentially ride and drive event.
Diamond Logic: Technicians are given training on the International Diamond Logic electrical system, which integrates with the International truck chassis to deliver precise, high performance diagnostics and customized solutions utilizing the vehicle’s electrical systems. In addition, as part of the program, International will waive the annual payment fee for both its Engine Diagnostic Software and Diamond Logic Builder, while enrolling members in automatic renewal for uninterrupted access.
All of these benefits are provided completely free of charge to Diamond Partners, and there is no fee for signing up.
