The inner axle tubes and knuckles on a stock JK Dana 30 or Dana 44 are weak points that can bend or break under hard use. This TeraFlex kit reinforces both. The inner axle sleeves cover the short and long side tubing, and the upper inner knuckle gussets stiffen the knuckles. The kit combines the Front Axle Sleeve Kit (4990700) with the Upper Inner Knuckle Gusset Kit (4990800). Install it, and the front axle is reinforced where it tends to fail.
