The B41684-1 Meritor gear set is a service ring and pinion set cut for a 3.90 drive ratio, using a 12-tooth pinion matched to a 41-tooth ring gear. Pinion is identified as 42135, and the set is listed for the Meritor RR22145 axle model. Ring and pinion are lapped as a matched pair, so both pieces are replaced together to hold proper tooth contact and quiet operation. Ratio accuracy matters on tandem drive axles, so confirm the ratio tag on both carriers before ordering. Call us to confirm proper fit for your axle.
