View Instructions Find a Distributor 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 Note Requires transfer case disassembly. Not for use in 2WD or earlier 47RE applications with NV241 transfer case. Contents Transfer Case Input Shaft Output Shaft with Bushings
