These heavy-duty ROUSH 31 Spline Rear Axle Shafts for the 2005-2009 GT Mustang are designed to replace and fit into the OEM factory parts.
ROUSH's axle shafts are part of the ROUSH Drag Pak Mustangs and are made from SAE 1541H steel that's 100% magna fluxed and induction hardened for maximum strength. The five lug, 31 spline has a provision for an ABS exciter ring and the axle flange wheel pilots are machined to OEM dimensions to center the factory wheels and reduce vibration.
