Forged wheel studs designed to be fitted as replacement extension studs to allow wheels where a longer thread is required.
The studs are mounted through the back of the wheel hub and the splines on the shoulder of the stud must exactly match the splines on the wheel hubs.
Note, it is important that the stud has the correct diameter where the splines are to match up into the hole in the back of your wheel hub. Applications such as Ford, Hyundai and Toyota have several spline diameter sizes in the studs available.
