Product Details

When you're rebuilding the starter system on your 1965-1988 Big Twin Harley-Davidson, getting the right bearing is key. This outer starter driveshaft bearing from Twin Power is designed to replace the stock H-D 9063, ensuring your starter can engage smoothly and reliably. It's a small but crucial part for getting your engine turning over, especially if you're working on a chain drive setup.

This bearing is well-built to handle the forces involved in starting your motorcycle. It fits a wide range of Big Twin models, from the early FX Super Glides to later FLST Heritage Softails and FXR Super Glides. Having the correct bearing means less friction and a more direct transfer of power from your starter motor to the engine's flywheel.

Make sure you have this bearing on hand when you're tackling starter repairs or upgrades. It's a straightforward replacement that can make a noticeable difference in how your starter engages and spins the engine.
