American Axle & Manufacturing Inc. (AAM) has released 4.56 and 5.13 ratio ring and pinion gear sets for the Ram and GM 9.25-inch front axles.

“These new gear sets are perfect for truck owners who want to upfit their four wheel drive setup with bigger tires, mudders and much more,” says Pat Angst, senior manager, AAM Aftermarket.

AAM part #40146855 is a 4.56 gear set for the 2007-2013.5 Ram 9.25-inch axle, AAM part #40146853 is a 4.56 gear set for the 2013.5 and newer Ram 9.25-inch axle, and AAM part #400244878 is a 4.56 gear set for the 1988 to current GM 9.25-inch axle.
