Using knowledge garnered over the past 30 years, the engineers at EI Consultants, LLC offer consulting services in product design and development. We currently provide consulting services to manufacturers 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.

Additionally, we offer complete vehicle and subsystem development for passenger cars and commercial vehicles, military and recreational vehicles, off-road and farm vehicles. Prototype development, fabrication and testing are available for framing, steering, suspension, drive train, ergonomics and body and plastics. Additional services available are suspension tuning and kit designs, design evaluation, drawings, and BOM’s. We can virtually test your product designs before manufacturing, compare design alternatives and optimize product design for manufacturability and cost reductions. With our engineer’s expertise, we can provide you with product renderings that are brochure-ready.

The role of an accident reconstructionist is to provide a forensic conclusion to the cause and events of an accident. Some accidents may involve passenger vehicles or consumer products, such as an ATV.

Many highway traffic accidents occur as a result of sudden tire failures. One particular kind of tire failure is called tread separation, and it can be especially dangerous in some circumstances. This kind of failure involves the outer steel belt layer of the tire peeling away violently, often without causing the tire to go flat.

Why is there statistically such a high number of rollover accidents and injuries involving UTV's and ATV's, such as the Yamaha Rhino and the Polaris Razor?
