KIBBLEWHITE Cylinder Stud Kit — 8 Pack, Black – 21-22 Sportster S, 86-22 Sportster

Precision-ground cylinder studs engineered to remove the imperfections of rough-milled material and reduce notch sensitivity. A radius is ground on the last thread to lower the likelihood of failure at that point, and threads are hydraulically rolled to create the strongest possible thread. Made from milled, certified aircraft-quality material with a 180,000 psi yield strength. Made in the U.S.A. 🇺🇸🔩
