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.

For the ultimate protection against shaft breakage in these applications, see Sonnax extreme duty output shaft kit 22173D-01K with larger, diameter 29-spline output shaft and corresponding transfer case input shaft.

• 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
