Newer Rangers (FX4 Level 2) have the superb Torsen auto torque biasing differential from the factory. They can also be retrofitted on older models.I'd love to have another Ranger, but with a limited slip this time. Open diff is so frustrating in snow haha.
Unlike clutch type LSD, that bind the two axle shafts together only after one side spins, the Torsen is torque sensing, and instantly sends more power to the side with more traction before wheelspin can happen. I've been using them for 20 years now, and swear by them.
