C-Clip Axle Set Ford 05 Mustang GT 31 Spline

The C-Clip Axle Set Ford 05 Mustang GT 31 Spline from MOSER ENGINEERING is designed for Ford performance enthusiasts looking to upgrade or rebuild their 2005 Mustang GT rear axle assembly. This complete axle set is essential for anyone replacing worn axles, upgrading to a performance differential, or completing a rear-end rebuild on the S197 platform.

C-clip axles are the factory retention design used in modern Ford differentials, securing the axle shaft within the differential carrier via a spring-loaded clip rather than a retaining plate. MOSER ENGINEERING's 31-spline axles provide enhanced strength and load capacity compared to stock components, which is critical when pairing with higher-output engines or aggressive driving. The 31-spline design increases contact surface area and torque-handling capability, reducing stress concentration during hard launches and sustained cornering.

These axles are manufactured to precise tolerances, ensuring proper fitment within the 2005 Mustang GT differential housing and maintaining consistent engagement with the splined differential side gears. Weighing 38.1 lbs for the complete set, these shafts integrate seamlessly with OEM and aftermarket differential carriers. This axle set is ideal for Mustang GT owners installing a limited-slip or locking differential, upgrading from a factory open diff, or restoring a damaged rear end after track use or drag racing.
