We took the hard work out of removing and reinstalling your differential! 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 holes every time. Available in 45mm or 38mm in the drop down.

• 38mm studs are used with OEM or regular subframe bushings.
• 45mm studs are used withthe 12mm riser subframe bushings.

You’ll need to pull the driveshaft to drop the diff. Use thread locker during install. Recommended for street or race use.
