Collection: Transmission bearings for Harley-Davidson, Indian, and metric custom motorcycles

The constantly rotating shafts and gears inside a gearbox can only move smoothly and precisely if the bearings are in perfect condition. Gearbox bearings support and position the gearbox shafts, minimizing friction and absorbing the loads generated during shifting. A worn or damaged bearing exhibits characteristic symptoms: unusual noise from the gearbox, rough or jerky shifting, or, in the long term, premature wear of the shafts and gears if the problem remains unresolved. Our selection includes gearbox bearings for Harley-Davidson, Indian, and metric custom motorcycles, ranging from factory-spec options to heavy-duty solutions designed for performance-enhanced gearboxes. Ball bearings, needle roller bearings, and other specially designed bearings are also available, tailored to the specific point and load within the gearbox. Quality gearbox bearings are manufactured with precision from durable materials to ensure long-term smooth, quiet, and reliable shaft support, even under intense use and high torque. Whether you're repairing a noisy or jerky gearbox, or performing a complete gearbox overhaul, you'll find the bearings that perfectly fit your motorcycle's gearbox.
