BDA-7039 or BDA7039 is a Mack differential assembly with casing and differential nest kit, sold by Pro Gear and Transmission. It is listed in our parts manual for the Mack CRD 93 / CRD 113 differential at item 49 and for the Mack CRDPC 92 / CRDPC 112 differential at item 51. A differential lets the two wheels on an axle turn at different speeds through a corner while still sending driveline torque to both axle shafts, and the side gears, spider pinion gears and spider in this kit do that work. The kit also brings the matched cones, washers, casing and case, so the carrier can be reworked from one box. Call us to confirm proper fit.
