8 3/4 3.91 SureGrip Limited Slip Differential rear end. It is a 489 case with a big yoke. I used this in my 1971 Dodge Dart for bracket racing. It has a new ring and pinion, bearings, and seals. I put maybe 50 passes on it. My car was only a high 13 second small block dart so it hasn't been stressed. I went back to 3.23 rear end for cruising. Call/Text David at 252-717-0457
