These bolt-in rear axle packages are designed to replace the original ’68-’72 GM A-Body rearend housing and are compatible with the stock 4-link trailing arm rear suspension found in your Chevelle/Malibu/El Camino/Sprint/GTO/LeMans/Tempest/F85/Cutlass/442/Special/Skylark/Gran Sport. The major advantages gained by upgrading to a Ford 9″ axle include a) greatly increased strength (reliability), b) the variability of the housing to accept almost any gear ratio from 2.47:1 to 6.14:1, c) a drop-out third member for ease of service, and d) steel axle retainers keep the axle/wheel in place in the event of axle failure. Here are the features you’ll find in our fabricated Ford 9 Inch axle kits:
New stamped steel housing center piece
New billet steel housing ends with oil seal surface (“Big New Ford” Torino-style)
3″ O.D. DOM 3/16″ wall axle tubes
