About This Product
This crankshaft pinion and sprocket shaft nut is a vital piece of hardware for 1954 to 1980 Sportster and KH models. Produced by Eastern MC Parts, it is manufactured from aircraft-quality steel and heat-treated to a Rockwell hardness of 61-63 to ensure it can handle the high-torque environment of the crankshaft assembly. Each nut is meticulously quality-checked for accurate dimensions, providing a secure and reliable fit. As a direct replacement for OEM 8011, this nut is essential for any bottom-end overhaul, ensuring that your pinion and sprocket shafts are fastened to factory-grade specifications for long-lasting engine performance and reliability.
