Vehicle Design and Development

mul7Using knowledge garnered over the past 30 years, we are assisting companies in designing and developing suspensions, tires, control systems and vehicle architecture to improve ride, noise, vibration and handling for increased customer satisfaction and safety. We have worked ---and continue to work--- with the Arkansas Children's Hospital and with the Consumer Product Safety Commission in reducing children's deaths and injuries through improved ATV and UTV designs.


With predictable steering and handling response the ATV and UTV vehicles steer better, ride flat over the whoop-de-doos, and protect against pitch and rollover.

We would appreciate the opportunity to examine your vehicle designs seeking areas of possible improvement.
