The Sonnax heavy duty input shaft comes with durability and performance features which are second to none. Instead of the OE two-piece shaft/hub design, this 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. This shaft is equipped with a 23-tooth input spline and 62-tooth clutch spine, and is compatible with OE seals and also comes with Goerend lube modifications.
