Info

These bolt-in rear axle packages are designed to replace the original '55-'57 Chevy rearend housing and are compatible with the stock leaf spring rear suspension found in your Tri-Five Chevy. 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.

  • 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
  • 31-spline axles w/ bearings, studs & retainers
  • 1/2"-20 wheel studs, 2" long
  • 5 x 4-1/2", 5 x 4-3/4" and 5 x 5" wheel bolt pattern
  • Jig welded suspension brackets for stock style suspension
  • Built to stock width
  • 54-1/2" housing flange to housing flange width
  • 26-7/8" and 31-1/8" long outside axle flange to end of splines

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

Notes

  • Rearend Housing 3rd Member Carrier Studs and T bolts are included
  • This is a reclaimed steel housing and may have minor cosmetic flaws
