Delivering outstanding protection against Chrysler 48RE shaft breakage, Sonnax extreme duty output shaft kit 22173D-01K features a unique combination of innovative engineering and quality manufacturing. Stronger materials typically used for improving weak parts can’t overcome the OE shaft’s small, 23-spline cross section. In addition to a materials upgrade, the Sonnax shaft features a significantly larger, 29-spline configuration that is based on the OE manual transmission spline.
- Larger diameter allows for increased cross-section to protect against breakage
- High-strength alloy balances the toughness required for shaft strength with the deep case hardness required for the one-way clutch race that is an integral part of the shaft
- Includes a matching New Venture 271/273 input gear shortened to match the installation depth of the 48RE transmission
