C-Clips Axles Sets GM 10 Bolt 8.5 28 Spline

The C-Clips Axles Sets GM 10 Bolt 8.5 28 Spline from MOSER ENGINEERING represents the gold standard for upgrading or replacing factory axle shafts on GM G-Body vehicles from 1982–1988. Whether you're restoring a Chevrolet Monte Carlo, Buick Regal, or Oldsmobile Cutlass, or building a high-performance street machine, these C-clip axles deliver the strength and precision required for reliable power transfer. Mechanics and enthusiasts trust MOSER ENGINEERING's reputation for manufacturing axle components that handle both daily driving and serious horsepower.

These axles are engineered to work with the GM 10-bolt differential carrier, featuring a 28-spline design that maximizes surface contact and load distribution across the carrier hub. The C-clip retention system—rather than traditional retainers—simplifies installation and allows for quicker axle removal during maintenance or rebuild work. Constructed from high-strength steel and finished in natural (bare) steel, each shaft measures 28.438 inches in length and accommodates the standard 5x4.75-inch bolt pattern common to G-Body vehicles. The pair weighs 31.75 pounds, reflecting the substantial material quality built into every component.

This axle set is ideal for anyone upgrading from worn or bent factory shafts, or for builders installing a modern 10-bolt differential in place of weaker original equipment. Installation requires basic mechanical skill—drain the differential, remove the cover, push in the axle shafts, and secure the C-clips in the carrier grooves. Ensure proper differential fluid service and verify spline engagement before road testing. These MOSER ENGINEERING axles are engineered to handle street duty, moderate racing, and restorations where reliability and correct fitment are non-negotiable.
