the iron housing will bend or the bolt that holds the mount to the housing will bend/break.

 

We have never had any problems with a steel housing or bolts bending/breaking. We try to steer all of our customers away from the aluminum housing. Weight wise, it is not even worth it to consider the use of an aluminum housing.

Some of the fastest S2K's are running with a steel housing without any issues.

 

I believe they are iron housings.

 

Apparently not!

Always a dick man. I said the aluminum diff will work just fine because there are several people that have had ZERO issues with them. If they cranked up the power then maybe they will but for the average person not beating the hell out of it on the track, the lincoln mark Viii, and cobra diff will work.

As far as the steel housings go, you can run any thunderbird super coupe / IRS diff from 89-95. Just make sure it says 8.8 on the housing because they do make an 8" believe it or not.

 

over 1100whp here and 8sec car numerous passes on it and never broke a steel housing or bolts... the only thing i broke was the ring and pinion on a really sticky track
