2011 Manual Gasoline mileage: 290 KM 3.55 differential fits any Ford car with an 8.8 differential directly. I bought it and it came with a clean center section, and the ring and pinion are all clean, but I haven't installed it yet. It's still in the shipping box, unopened. Whoever wants to inspect it is welcome. Note: When installing the differential, you must balance it properly with someone knowledgeable to avoid whining. It was offered for 600 SAR. No warranty.
