Meritor service gear set B41650-1 or B416501 is a matched ring-and-pinion set engineered for RRXX180 and RSXX180 axle models. The set runs a 7.83 ratio, achieved through a 37-tooth ring gear paired with a 9-tooth pinion (pinion part number 41907). That deep ratio suits heavy-duty vocational and linehaul rear axle configurations where low-end torque multiplication is the priority. Both part number formats, hyphenated B41650-1 and non-hyphenated B416501, reference the same Meritor service gear set. Call us to confirm the ratio and pinion number match your specific axle build before ordering.
