Kevin’s Story: Muddy Bottom Mini Trucks

Cricket Rumsey, General Manager at Newcomb Spring of Texas, recalls the day Kevin Seymour reached out to him.

“Kevin bought some aftermarket [springs] that didn’t work, and he needed something different, but he wasn’t sure exactly what he needed. He brought in the stock spring and the underperforming aftermarket spring and began discussing his vision for the design.”

Kevin’s vision extended beyond the functionality of the spring; he wanted a stronger spring that performed exceptionally well but also stood out visually among other suspension springs on the market. Cricket and the team got to work designing a working prototype that achieves the balance of visual progressiveness desired while adhering to specific dimensions needed functionally for the PowerFlex design.

The prototyping phase continued to be a collaborative effort. The Texas team meticulously crafted samples, ensuring the physical appearance of the suspension spring didn’t compromise its functionality. Kevin actively participated and spent an entire day on the production floor fine-tuning the design with the team. The efforts of both Newcomb and Kevin paid off when they achieved a sample that closely matched Kevin’s desired product.

The Product: PowerFlex Suspension Spring

Designed for durability and aesthetic appeal, the PowerFlex suspension spring undergoes several specialized processes to enhance its functionality, such as shot peening, presetting, and powder coating.

The spring is expertly engineered with a progressive design that significantly boosts its performance. It features variable pitch with certain coils absorbing minor bumps while others activate only to absorb larger forces such as potholes and off-road terrain. This design progressively increases the spring rate as it compresses, allowing the spring to handle transitions in terrain smoothly. This innovative design makes for a smoother ride and reinforces its durability.

When asked why he chose Newcomb Spring over the other spring companies he contacted, Kevin explained how the team at our Texas facility was more than willing to work with him when other spring makers were not.


“They had to do a lot of educating me so that I knew what I was asking for. The end product is so much better because of that. There’s a lot more to making springs than I had any clue of.” Kevin remarks.
