Sonnax Extreme Duty Output Shaft Kit
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.
