Description
48RE Extreme Duty Output Shaft Kit, Sonnax 22173D-01K.
For use in ’03–’06 4WD models only with NV271 or NV273 transfer cases.
Delivering ultimate 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. The Sonnax shaft features a significantly larger, 29-spline configuration that is based on the OE manual transmission spline. At 1.480″ dia., this high-strength alloy shaft delivers 50% more strength than OE-size, aftermarket shafts.
For applications where replacing the transfer case input shaft is not an option, see Sonnax heavy duty output shaft 22173D-HD.
- Larger, 29-spline 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
- The included New Venture 271/273 input gear is ready for install — no machining required
- Requires transfer case disassembly.
- Not for use in 2WD or earlier 47RE applications with NV241 transfer case.
- Transfer Case Input Gear
- Output Shaft with Bushings
