• CV Drive Shaft | Rear | Jeep Wrangler Unlimited 4WD (2007-2011) • This double cardan style CV drive shaft is necessary for Jeep JK models equipped with 3.5in - 6in short arm suspension lifts or 2.5in - 6in long arm suspension lifts. It features a replacement flange for the differential pinions as opposed to using an adapter flange. These flanges are machined from solid billet steel. They are designed to accept standard off the shelf mating flanges. If these flanges ever break, you at least stand a chance of getting a replacement part from almost any drive line shop. This also nets a longer drive shaft with the center of the universal joint closer to the pinion bearing. • 5099.1
