The inner axle tubes on a stock JK Dana 30 or Dana 44 are weak points that can bend under hard use. This TeraFlex kit reinforces them with an inner axle sleeve for the short side and one for the long side. The sleeves are sold together as one kit. Install the sleeves, and the axle tubing is better protected against bending or breaking under extreme conditions.
