7S. Sonnax and PATC now offer this heavy duty, one piece input shaft and clutch hub for the Dodge A618 in the 1994 – 2007 Cummins Turbo Diesel application. Can be used in a 2003 up 48RE transmission with Red Eagle clutches. By combining the input shaft and forward clutch hub into a one piece design, Sonnax has eliminated the weak connection between the two. This new assembly is made from a high strength one piece 300M steel forging, which adds to the overall strength of the design.
