4 Drilled Holes on 4.750BC, Ø3.750-F pilot
This 1410/1480 series companion flange is designed for the GM Corporate 14, 14 bolt, 10.5' ring gear axle found in many 3/4 and 1 Ton Chevy and GM trucks from 1973 to today.
For 1998 and earlier applications, this flange can be used directly with the existing pinion seal.
For 1999+ applications, the pinion face seal AAM-26060977 must be purchased and installed on the hub to match the pinion seal diameter in those axles.
