GMB CORPORATION

GMB Corporation is a Japan-based manufacturer and distributor of automotive components, specializing in cooling system parts (water pumps, fan clutches, bearings), drivetrain and powertrain components (universal joints, CV joints, steering joints), and suspension and axle parts. The company serves two distinct markets: the global automotive aftermarket (replacement/repair parts), primarily through its Japanese headquarters and North American subsidiaries, and the OEM new-vehicle market (supplying directly to automakers and their Tier-1 suppliers), primarily through its Korean subsidiaries GMB Korea Corp., GMB AGtech Corp., and GMB ELPIS Corp. GMB's competitive strengths lie in its broad product lineup under the GMB brand, global manufacturing and sales network spanning Asia, North America, Europe, and Oceania, and ongoing R&D capabilities in both Japan and Korea.
