Total Cost Involved Engineering (TCI), the Ontario, California-based manufacturer of chassis and suspensions, is celebrating its 50th anniversary in 2024.

The company is celebrating the milestone by offering discounts on freight expenses for its products. The company will cover the full cost of freight for front and rear suspension purchases and provide a 50% discount for freight for the purchase of a new chassis. The promotion is available through the end of September.

TCI was founded in 1974 by Ed Moss, the current owner and president of the company, and its first product was a newly designed and engineered Model A chassis. Today, TCI operates from a 32,000-sq.-ft. facility in Ontario, California, ships globally and employs more than 50 employees.
