Rocker Arm Stud Girdle Replacement Nuts

7/16 in.-20 Thread

Polylock Design

For AFR Stud Girdles

Set of 8

A stud girdle only keeps the valvetrain rigid if the nut underneath it is built to accept the girdle bar, and a standard rocker nut will not index correctly once the girdle goes on. This polylock nut is machined to seat under an AFR stud girdle so the rocker stays locked in place.
