BMW DIFFERENTIAL STUD KIT - E30, Z3, E28 OVERVIEW Introducing our diff stud kit conversion. This is one of those mods that you will be glad you did, the next time you need to service your differential. This makes taking the differential in and out of your E30, E28, or Z3 a lot easier. This now becomes a one person job (and safer). It can be a little difficult to balance the differential and line up the bolt holes during re-installation. They never seem to line up perfectly you need to make sure that the bolts are threaded by hand first. It can be time-consuming. Our diff studs are designed to make everything line up and lift right into the holes every time. Installation is easy. Simply apply Blue Loctite on the studs. Thread to the length you require and let the thread lock dry. That's it! Set includes everything needed for installation including nylon locking nuts and washers. Fitment WHAT BMWS CARS WILL THIS DIFF STUD KIT WORK ON? E30: All Models Please Note: If you are running RAISED SUBFRAME BUSHINGS and a CENTERED DIFF BUSHING you will need our extended diff studs and spacers to mount your diff properly. E36/5: 318ti E36/7/8: Z3 Models Installation Notes Stud Allen Size: 5.5mm Stud Torque Spec: 25 ft/lbs + Blue Loctite Nut Socket Size: 19mm Nut Torque Spec: 45 ft/lbs Highly Recommended: Put Blue Loctite on Stud Before Threading into Differential. Note: We typically recommend installing only the front 2x studs, and use the factory bolts for the rear mounting positions. This makes it easier to position the differential into the subframe.
