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.

    Have many out there with 100k plus on them and no issues towing heavy. Abuse will lead to a failure eventually. At nearly 1500hp they are holding still on one of our builds.
