Description
The Meritor A39664-1 or A396641 is a genuine OEM service gear set engineered for RDXX160 and RPXX160 drive axles. It carries a 4.89 ratio, pairing a 44-tooth ring gear with a 9-tooth pinion (Meritor pinion number 39889). These specs make it a direct, application-specific replacement rather than a universal gear set, the ratio and tooth counts must match your existing axle configuration exactly. Call us to confirm proper fit for your axle before ordering.Interchanges:
