Is that for a 60? I've got a couple of them, but sold my truck before I installed one. They are an OK choice for a street driven limited slip. Use Belleville springs for clutch pack pre-load and they have a reputation for wearing reasonably quickly.

Dollar per dollar, least expensive way to get a clutch type limited slip in a Dana 60. The Powerlock is the preferred Dana limited slip, but they are three times the price. 3 times as good? Arguably I guess, but I have no qualms about installing and running one FWIW.
