Supreme produces over 8 million shift levers a year, both out of tubing and solid bar. Over our 40 years of producing shift levers, we’ve continued to improve our processes, embodying one of our bedrock principles - continuous improvement.

Through these improvements and the evolution of our processes, we have been able to significantly reduce our costs while continuing to meet the increasing expectations of our customers. That means you get a better product at a lower price.

We have experience using a wide array of material, such as Stressproof, 1045 in solid bar and, 1020/1026 in tubing, to name a few. Our customers’ feedback is important; we are always open to suggestions and recommendations on the design that will reduce the cost of the lever, while still achieving the functionality of the lever. We make over 60 different models of levers globally with a wide range of styles and sizes.

With our extensive experience, there are very few products we have not produced. If you need it, we can make it.
