Details
These bolt-in rear axle packages are designed to replace the original GM X-Body rearend housing and are compatible with the stock multi-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 wheel studs, 2″ long
- 5 x 4-3/4″ wheel bolt pattern
- Jig welded suspension brackets for stock style multi-leaf suspension
- Built to stock width
Add third member and brake kit of your choice (both sold separately) to complete your installation.
