  • 1480 series uses a 1.375" U-joint cap diameter -- a significant step up from the 1.188" cap of the 1350/1410 series, rated for medium-duty truck and severe off-road applications
  • The 4.750" bolt circle and 3.500" pilot are larger than light-truck flanges -- confirm the mating companion flange dimensions before ordering
  • 4 x 0.500" bolt holes require grade 8 fasteners at minimum; SAE grade 8 or metric 10.9 recommended for this torque level
  • Do not mix 1480 and 1550 series components -- the cap diameter differs (1.375" vs 1.375" OD but different cup depth), causing improper U-joint seating

The 1.500" C/joint-to-flat dimension is shorter than the 1410 series equivalent -- verify total driveshaft length when substituting a 1480 flange yoke for a lighter-duty fitment. The 1480 series flange yoke is commonly found on medium-duty trucks with Dana 70 and Dana 80 differentials.
