48RE 47RE Heavy Duty 4WD Output Shaft Sonnax Number 22173D-HD. Delivering 25% more strength. OE Part Number 5093156AA. For use in 4WD models only.
Sonnax heavy duty output shaft 22173D-HD is a direct replacement upgrade for 23-spline OE shafts in Chrysler 48RE and 47RE transmissions. These shafts are at risk for breakage at the output spline area, especially in high horsepower/torque vehicles. Delivering a 25% increase in strength compared to OE and significantly stronger than other aftermarket, 23-spline shafts, the Sonnax shaft features improved material plus an optimized spline design to guard against failure.
- Direct replacement upgrade for OE 23-spline output shaft protects against breakage
- High-strength alloy balances the toughness required with the deep case hardness required for the one-way clutch race that is an integral part of the shaft
- Hobbed output spline eliminates undercut where OE shafts fail
