A Customer-Driven Origin Story

After serving as a Pilot in the Army Air Corps during World War II, Bob DeLong Sr., the founder of Superior Spring, worked as a sales representative for a tool and die company based out of Minneapolis, Minnesota. During one of his sales calls, a customer asked him for something that the company did not offer: a SPRING. Recognizing a window of opportunity, Bob pulled out his phone book and located a spring manufacturer that was able to create the spring that his customer needed.

Realizing that many of his existing customers expressed this same need is what led him to the start of the new business: Superior Spring Company. Over the years, Bob transformed his new venture from a side business, into the thriving company that it is today.

A High-Tech Company with a Family Touch

Since its inception, Superior Spring has grown steadily. It has manufactured millions of individual springs and continually strives to maintain state-of-the-art production and performance efficiencies by investing in the latest spring making technology and inspection equipment.

As a family-owned and managed business, Superior Spring takes pride in being one of the most comprehensive and innovative suppliers to its customers. Our customers demand products that meet exact specifications and the highest of quality standards. When our customers come to us with a pressing need, they can rest assured that we will partner with them to create, manufacture, process, and quality-test their design in our spring and materials testing lab. Our main focal point is to bring in as many processes and operations in-house so that we have total control over not simply the manufacturing process, but the finish processing as well.

With a world class on-time delivery rate of 99.9%, Superior Spring strives to provide our customers with first-class customer service and satisfaction.

An Innovative Future You Can Count On

Superior Spring believes in investing in the technology, equipment, and people that accelerate its growth year after year. Upon taking over operations in 1993, Bob DeLong Jr. expanded Superior Spring from its humble beginnings in El Monte, CA to its current, state-of-the-art facility located in the heart of Anaheim, CA.

Current Vice-President, and third-generation management, Brad DeLong, joined the company in 2008. Brad adds to the decades of experience and expertise with his forward-thinking approach to the business. As he innovates, he continues to instill the family traditions and values that are key to the strategic vision for success at Superior Spring.

Superior Spring is constantly adapting and evolving to match the needs of the industries and customers we serve. We pride ourselves in making every one of our partners feel as though they are part of our family, from our devoted employees to our impressive list of customers.
