The COMP Cams stud-girdle adjusting nut with retaining ring is a 3/8" rocker nut engineered to lock stud girdles securely under moderate lift and spring pressures commonly found in race and high-load applications. At 2.000" overall length, the polylock includes a snap ring to hold the girdle bar. Precision grinding and a tapered locking area help minimize runout and improve clamping strength.
