GM 10 Bolt 7.5 C-Clip 26 Spline Axles 28-7/16in

The GM 10 Bolt 7.5 C-Clip 26 Spline Axles by MOSER ENGINEERING represent a direct replacement solution engineered for classic GM G-Body vehicles from 1978 to 1981. These 28-7/16-inch axle shafts are constructed from steel and feature a C-clip retention system paired with a 26-spline carrier design, making them a bolt-in upgrade for restoration projects and performance builds requiring OEM-specification components or higher-quality alternatives to factory originals.

The 26-spline design ensures robust power transmission through the differential, while the 5 x 4.75-inch bolt pattern maintains compatibility with stock and upgraded rear axle housings. The C-clip retention method is characteristic of early GM 10-bolt differentials and requires proper installation to prevent axle shaft separation during extreme load conditions. At 29 pounds per pair, these axles meet the structural demands of street-driven classics while remaining accessible for owner-level installation and maintenance. The natural steel finish requires protection against corrosion and should be properly sealed before road use.

This axle pair addresses the needs of G-Body platform owners—including Chevrolet Malibu, Pontiac Grand Am, and Oldsmobile Cutlass builders—who require dependable rear-axle componentry for restoration, daily driving, or mild performance applications. Choosing quality aftermarket axles like these MOSER ENGINEERING units reduces the risk of catastrophic failure associated with aged OEM shafts, particularly in vehicles that have accumulated significant mileage or will see increased duty. Installation requires appropriate tools and differential knowledge; consultation with a qualified technician is recommended if you lack experience with rear-axle assembly work.
