Info

These bolt-in rear axle packages are designed to replace the original GM X-Body rearend housing and are compatible with the stock mono-leaf spring rear suspension found in your '68-'72 Chevy II/Nova/Ventura. 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
  • 31-spline axles w/ bearings, studs & retainers
  • 1/2"-20 X 2" & 7/16"-20 X 1-11/16" long wheel studs included
  • 5 x 4-3/4" wheel bolt pattern
  • Jig welded suspension brackets for stock style mono-leaf suspension
  • Built to stock width

Notes:

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

Notes

  • Rearend Housing 3rd Member Carrier Studs are not included but available as # 919-0915 as needed
Some parts are not legal for use in California or other states with similar laws/regulations
