  • Since the very early 1950s, B&M has been at the vanguard of the growing automotive aftermarket. Racers themselves, B&M's founders identified the needs of local racers and street performance enthusiasts, and developed products to fill those needs. As the industry grew so did B&M. And as racers went faster, B&M developed products to help them break the records they just set.

    In the 50s it was B&M who came up with the idea of using a performance reinforced Hydramatic for racing. In the 60s it was B and M who developed shifters to go along with it, and later in the decade came race converters. In the 70s shift and transmission improving kits, and always the constant refinements and expansion of existing product lines.

    If you've ever raced a vehicle, or driven a hot rod with an automatic transmission, high stall torque converter, an aftermarket automatic shifter, or performance enhancing shifting kit - thank B&M. From Trick Shift performance ATF to reverse pattern valve bodies, 1.80 gear sets to cool canisters, the list of firsts goes on and on.
