A3226Z1222 Meritor Cage Assembly

Meritor cage assembly A3226Z1222 is a differential component used in heavy-duty drive axle carrier builds. The cage carries the differential spider, side gears and pinion gears, keeping them aligned under load so torque splits correctly between the axle shafts. It is sold by Pro Gear and Transmission as a Meritor part under UPC 737238497349. Cage assemblies are typically replaced during a carrier teardown alongside bearings, shims, thrust washers and cross shafts, so ordering the matching support parts at the same time saves a second teardown. Give us a call with your axle model and carrier tag information and we will confirm this is the right cage for your build.
