Description
The Meritor A39882-1 or A398821 is a genuine OEM service gear set engineered for RDXX160 and RPXX160 drive axles. It delivers a 4.56 ring-and-pinion ratio using a 41-tooth ring gear paired with a 9-tooth pinion (Meritor pinion part number 39887). These counts and the 4.56 ratio are specific to this gear set, so confirming the axle model and existing ratio before ordering prevents a misfit.
