Overview
The GM 12 bolt 8.875 inch replacement rear axle shaft, part number 95-2019-002, fits GM 12 bolt axles and has 30 splines. It is for the driver or passenger side, and the shaft is forged from high grade alloy steel.
The shaft is heat treated to exceed OEM specifications, and G2 positions it for owners who run larger tires and need more torque capacity than a factory shaft offers.
Key features
- Forged high grade alloy steel body
- Heat treated beyond OEM specifications, per G2
- Rolled splines and improved materials
- Suited to high torque and larger tire setups
- Big Spline options offered by G2
Torque and tire size
Rear axle shafts on GM 12 bolt car axles transfer engine torque to the wheels, and the load rises with bigger tires and more aggressive driving. The splines at each end see most of the stress, so they are the first place to look for wear. A shaft that has been driven hard for years may show slight rounding or play that is easy to miss until it becomes a noise or vibration.
Shaft condition is tied to the rest of the axle. The wheel bearing, the seal and the brake hardware all affect how the shaft runs. If you upgrade the shaft for heavier loads, check these parts too, and keep the axle type and spline count on hand so the new shaft matches the housing.
- Look for rounding or play at the spline ends
- Check the wheel bearing for heat or noise
- Inspect the seal for leaks before fitting
