Heavy Duty Input Shaft
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.
- Heavy-duty, one-piece design eliminates weak connection between input shaft and forward clutch hub
- Custom forged from ultra-high strength 300M steel
- 23-Tooth input spline, 62-tooth clutch spline
- Shaft can be used with OE seals
