Closure of 8.8 Ford axle swaps

[Blue Knight]

A nine inch could be done relatively cheap for someone with a good shop and skills. I thought about building one cheap but i came to a dead end with shortening and re-splining the stock axles. The 8.8 can take some abuse and they are cheap and easy to find. Still need to convert the wheel bolt pattern though and i'm not sure on their width. I think that by the time you did a 8.8 right, you could probably do a GN 8.5 for the same price or close to it. Just depends on what you pay for the core.

I have an 8.8 in a mustang with a BBC. Its got the JY aerostar 5 lug axles. Everytime i hit the throttle i expect one to break. I've run 12.04 at 111 mph with slicks but thats probably pushing my luck. The axle that spent its whole life in an aerostar turning one direction then swapped into my mustang turning the opposite direction will be the one that breaks. They don't like being un-twisted!
Plus they are just 28 spline!

Thats why I pulled one out of a ranger...it keeps the rotation the same anyways.

I to want to know all dos and donts, I can purchase a 8.8 fox rear with brand new 4.10 gears already installed for 200 bucks complete.
I just broke all of my pinion and ring gear teeth off of my 7.5. I just dont want to have a ton of money into this rear when I can purchase a drop in 9". If I can get it done under 500 I think it is a no brainer.

ford 8.8 swap

I see quite a few vic/mustang 8.8's swapped into g bodys and quite a few people use the trz motorsports swap kit. My problem is I opted for the explorer rear because of the 31 spline axles, true trac locker, and disc brakes. Two big problems are the leaf spring setup and the offset diff. I...

is the axle swap just to get the 5 lug axles?

yes but also gets you bigger brakes on the back.
