Stock front axle shafts are a known weak point on a built JK. The TeraFlex Tera44 HD Wide Left Inner Front Axle Shaft replaces the stock shaft with a heavy-duty one for the 70 in wide Tera44 HD front axle. The 30-spline inner shafts work with most aftermarket lockers, such as the ARB RD117. Slide it in, and the left side drives with a stronger shaft.
