About This Product
When it comes to the bottom end of an Ironhead or early Evo Sportster, precision is everything. This crankshaft pinion and sprocket shaft nut from Eastern MC Parts is a high-quality replacement for 1981 to 1985 Sportster models. Manufactured from super-tough, aircraft-quality steel and heat-treated to a hardness of 61-63 on the Rockwell scale, it is built to withstand the intense stresses of the crankshaft assembly. Each part is quality-checked for accurate measurements to ensure a perfect fit. Replacing your old hardware with this nut, which corresponds to OEM 23902-81, provides the peace of mind that your pinion and sprocket shafts are secured to professional standards.
