The NV5600, which was produced at New Venture Gear's Muncie, Indiana plant was an option on 1999-2005-1/2 Dodge Ram 2500 and Ram 3500 trucks with either the Cummins Diesel or V10 gas engine. The early NV5600, which is found on 1999 and 2000 trucks had a 1-1/4" input shaft and fiber-lined synchronizer rings. The input shaft was beefed up to 1-3/8" for the 2001 model year after one of the 1-1/4" shafts failed behind a Cummins High Output engine during a long-term Chrysler engineering road test. Also for 2001, the synchronizer rings and gears were redesigned. Except for the shift tower stub length change for the all new 2003 body style, very little significant engineering changes were made between 2001 and the end of production in January of 2005.
