10. Here are the two wheel hub options for the ProRock 80. To the left is the hub that went in our axle and allows us to retain the wheel sensors. The wheel sensors in a JK are used not only for ABS but also for the speedometer unlike earlier Jeeps. If you don’t need the wheel sensors, or are carrying a lot of weight, the 10K wheel hub might be for you. Dynatrac calls it 10K because it is designed for vehicles with a 10,000-pound curb weight. Or something that might see 15,000 to 18,000 pounds when loaded up.
