Since 1979, SCS Gearbox, Inc. has been listening to its customer’s needs and demands and that is what has kept us going over the years. When we first started manufacturing, it was strictly to meet the needs of truck and tractor pullers. The goal was to provide specialized gearing for their tractors that was easily interchangeable to meet track conditions, this goal was met, and well exceeded. As our reputation for producing a quality product spread throughout the racing industry, customers from around world and from all aspects of racing have called us to see what we can do for them. As a result, we have developed and manufactured a product line for more than just tractor and truck pulling. Over the years we have opened our focus to cover tractor pulling, monster trucks, mud boggers, circle track, motorcycles, International and Domestic Offshore boat racing, and many more. The innovation process never stops! We are always looking for what is best for the customers and looking to help you Go-Faster and Be-Stronger!
