47RE, 47RH, 48RE

Heavy Duty Input Shaft
Part No. 22121B-01

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
