About B&M ShiftersAll B&M products are designed here in the USA by in-house engineers. B&M uses only the finest material and hold the assembly of our products to the highest tolerances. Please assure yourself of the B&M quality and don’t confuse it with that of lesser or foreign manufactures. Who else provides a lifetime warranty on many of their products? B&M's philosophy has always been to build the best parts available, at any cost, and the racing world has responded by making B&M the #1 performance transmission company in the world!
