B&M Racing has been at the forefront of the automotive aftermarket since the early 1950s. Its founders, who are racers themselves, identified the needs of racing/performance enthusiasts and fabricated products to fill those needs. This includes shifters, coolers, transmission pans, differential covers, performance transmissions, and more! To this day, B&M Racing remains at the vanguard of the aftermarket world, leading and setting new standards through its consistent development of cutting-edge products. The brand is dedicated to addressing the ever-changing needs of vehicles and consumer demands, whether it is for racing, everyday use, recreational use, or for mere upgrade purposes. No matter the application, B&M Racing offers quality reliable products that get the job done.
B&M Racing recently discovered several fields in the off-road market that it felt needed more attention – particularly in the UTV area. And so, B&M Racing joined forces with industry-leading Flowmaster to form the XDR Off-Road Group. Together, they released a number of gated shifters, exhausts, and accessories for highly popular vehicles like the Can-Am Mavericks, Polaris RZRs, Yamaha YXZ1000s, and Textron Wildcat XXs.
B&M Racing’s Many InventionsIt was B&M who came up with the idea to use a performance reinforced Hydramatic for racing in the 1950s. Then in the 1960s, it was B&M who developed shifters and race converters to accompany it. In the 1970s, B&M Racing debuted its shift and transmission improving kits. As racing and street performance increased worldwide, B&M Racing used its extensive experience and know-how and applied it to the needs of everyday drivers, racers, and gearheads around the globe. The company takes pride in being among the very first to identify a vehicle’s needs in the aftermarket and supply car enthusiasts with exactly what they need to succeed.
