Rear Axles - 31 spline, Big Bearing, 1/2'' Retainer Bolts, 66-75 Ford Bronco
$310.00
New 31 Spline Axles for 66-75 Broncos with Big Bearing 11 inch Drum Brakes. Axles come with wheel studs, Set 20 Bearings and seals and retainer plates. These axles fit 66-75 Bronco's with 3 1/8 diameter bearings and 1/2'' retainer bolts and 11 drums.
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.
These axles are heat inducted and have rolled splines for hard core use. The set 20 Bearing is lubricated by the differential gear oil for extended bearing life and heavy load capacity. Drum measurements are made from the inside of the drum.
