Ford 9" 31 Spline Light Weight Full Spool
Suit 3.062" Bore Case
The Aeroflow Performance Ford 9" 31 Spline full spool is designed to give you the traction that you need by locking the axle shafts together, forcing your rear tires to turn at the same speed. This eliminates the gear failure caused by case deflection or differential side-gear failure. This lightweight steel spool weighs only 6.1 lbs.(2.76kg). Designed to suit 3.062" bore Ford 9" case.
NOTE : All Ford 9" full spools use overhaul kit AF5076-1003. This contains the larger I.D. standard O.D. carrier bearings and pinion bearings needed for use with the full spools.
