The 4340 Chromoly Inner Axles receive a special "through" hardening and are cryogenically treated making them the strongest aftermarket axles out there today.. They have a fully machined and polished seal surface and all 30 spline shafts come with c-clips already installed. These shafts are great for replacements or spares.
Note: 27 Spline shafts are shipped as shaft only and do not include c-clips.
