If you've ever taken out your diff, you know how much of a pain it is to get the bolt holes to line up during re-installation. They never seem to line up perfectly, and getting the bolts to go in can be time-consuming. Our diff studs are designed to make your life a little easier. The diff will line up and lift right into the subframe holes every time. Available in 45mm or 38mm in the drop down. Recommended for street or race use.
