There are many different ways to build a drive shaft for the new JK. With our version, we’ve elected to make a replacement flange for the differential pinions. These flanges are machined from solid billet steel. We designed this 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 centre of the universal joint closer to the pinion bearing.

Unless you plan on beating the vehicle really hard, we believe the 1310 series front drive shaft would serve most people well.
