GM 10 Bolt 7.5 C-Clip 26 Spl Drilled 5/8 Studs

The MOSER ENGINEERING GM 10 Bolt 7.5 C-Clip 26 Spline Drilled 5/8 Studs axle shaft is a purpose-built component for classic GM G-Body muscle car and street machine restoration and high-performance modification. This 28.438-inch axle shaft delivers the structural integrity and precision fit required for reliable torque transfer in vehicles equipped with GM's robust 10-bolt differential housing, making it essential for enthusiasts rebuilding or upgrading rear-end assemblies in 1978–1981 G-Body platforms.

This axle shaft features a 26-spline carrier engagement, C-clip retention system, and drilled 5/8-inch studs sized for the 5x4.75 and 5x5-inch bolt patterns common to second-generation Chevrolet Malibus, Pontiacs, and Oldsmobiles. The natural steel construction provides excellent durability and straightforward installation into stock or upgraded 10-bolt carrier assemblies. The drilled stud design accommodates wheel bolt patterns across multiple G-Body configurations, eliminating the need for adapter plates in most applications.

Buyers undertaking a complete rear-end rebuild—whether for stock restoration, suspension upgrades, or moderate performance enhancement—rely on Moser Engineering's precision tolerances and metallurgy to ensure smooth operation and long service life. This component is particularly valued by fabricators and restorers who demand OEM-compatible fitment without surprises at final assembly. At 15 pounds, the shaft's robust construction reflects its load-carrying capability without unnecessary weight penalty.

The GM 10-bolt differential housing remains the industry standard for budget-conscious performance builds and stock restorations alike. Moser Engineering's axle shaft lineup supports both street applications and moderate track use, offering enthusiasts reliable drivetrain components that respect original specifications while supporting modern driving demands.
