Smile 8.8?

Just wanting to find info out about the ford 8.8 axle. Is it a pain or time consuming? Can it be done with average tools? Up to what size tires can be run on them? Do they have the same measurements as the d-30 and d-35. Last of all what makes them so much better?

the 8.8 is about 1.5 inches narrower than the d35, same bolt pattern, 4x stronger in stock form. U need to move the spring perches on the 8.8 to match up. pay attention to ratios so they match front to back. oh yeah and added bonus 8.8 lets you run discs in the rear without much hassle too.

A quick list of things you'll need for an 8.8:

- The axle itself with appropriate gears (or be prepared to regear both axles like I am)
- A perch kit with a welder to weld the new perches on
- Conviction on whether you want to go SOA or not. If you do want to do spring over, now would be a time to do it.
- Plan on rebuilding all of the incidentals (rotors/pads/etc.) if you're getting a junk yard axle.

Doing this myself right now but going a few steps above with chromoly shafts and C-Clip eliminator.
