This trap door can be used as a heavy duty stock replacement or as a rigid backbone for drag racing and high output 4 speed alternator-equipped Sportsters®. Includes a heavy-duty, double-row mainshaft bearing for extra strength and stability for the clutch and shafts. The double-row bearing greatly reduces the clutch shell rocking that occurs under power – which leads to damaged alternator rotor magnets and stators when contact between the two is made. It is a direct bolt-on replacement and includes mounting hardware and countershaft bearing. Made in USA.
