These bolt-in rear axle packages are designed to replace the original '64-'67 GM A-Body rearend housing and are compatible with the stock 4-link trailing arm rear suspension found in your Chevelle/Malibu/El Camino/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 ford old style bearings)
  • 3" O.D. DOM 3/16" wall axle tubes
  • 31-spline axles w/ bearings, studs & retainers
  • 1/2"-20 wheel studs, 2" long
  • 5 x 4-3/4" wheel bolt pattern
  • Jig welded suspension brackets for stock style suspension
  • Built to stock width
  • Works with most aftermarket coil-over conversion kits

Add third member and brake kit of your choice (both sold separately) to complete your installation.
