31 Spline Driver Rear Axle, 11 in Drum, 76-77 Ford Bronco

New 31 Spline Heavy Duty Driver Side Axle Shaft for 76-77 Bronco. Axle comes complete & assembled.

Our 31 spline axle shafts are up to 60% stronger than factory 28 spline axles! This is achieved by compounding the added strength of using more splines which are rolled rather than cut with the use of stronger 1541H heat treated steel.

Drum measurements are made from the inside of the drum.
