We're jumping the gun on this one here, but these are the new Rock Jock JK replacement axles. The Rock Jock JK housings are made with all the brackets and mounting points to hook up to the factory-style suspension under JKs while utilizing the outers (front and rear) of the original axles. In the rear, you just bolt the factory brake bracket and disc brakes back on, retaining all the sensors. In the front, the JK Rock Jock will reuse the factory knuckle and retain the brakes and sensors there as well. On a side note, in the photo you can make out a few of the pieces of the new Currie JK suspension kit that this Rock Jock is hanging from.
