47/48 Input Shaft For Chrysler A618, 47RH/RE and 48RE Diesel Performance Converters

Description

Designed for hard-working Chrysler A618, 47RH/RE and 48RE units, Sonnax heavy duty input shaft 22121B-01 comes with durability and performance features which are second to none.

Instead of the OE two-piece shaft/hub design, the Sonnax shaft uses a much stronger, one-piece design that combines the input shaft and forward clutch hub, eliminating the weak connection between the two. The Sonnax shaft itself is custom forged from ultra high-strength 300M steel to allow the internal grain structure of the steel to follow the general shape of the part, improving shaft strength. It remains one of the most popular upgrades for hardworking Dodge trucks.
