Ford Super 8.8 irs swap thread. Rear brakes too

Recommended Posts

Putting in my order for this set-up has rejuvenated interest in my Z. This Super 8.8 swap is something I can actually afford. Better struts, serviceable diff, stronger axles, hubs, and companions, 5 lug swap, bigger brakes, all pretty much bolt on parts with minor fabrication. Thrifty shopping and planning will make this whole swap significantly less than a set of aftermarket R200 axles. Plus I can buy the replacement parts from local parts houses. I'm stoked! Thank you for following through with your word and actually bringing something to market. Who needs an obx fitted 3.36 R200? I'll have one available soon. 😜🤣🤣

Have you sourced the super 8.8 assembly? Just curious what they get for them and what stock gear ratio are available out there..

Entire rear subframe can be had for anything from 500 to 1200 plus freight. 

 

Just the bare diff itself ranges from $100 to $900 and is available in 3.15, 3.31 all the way up to 4.09 factory.  Aftermarket 4.56 gears are also available.

 

The most common ones are 3.15 from a v6 rental and 3.31 off an ecoboost.

 

Ebay is full of them, ALL have lsd but some even come with torsen.

Yes, I got a 3.31 iron housing (manual trans car) from LKQ. Prices at LKQ for the diffs alone are pretty cheap, they go from $220-$600. Mine has 67k miles on it and was advertised at $260. They charge more for those labeled "clutch type lsd", but as said above, that's what they all are aside from the torsen ones.

I am running   r200 /zxt axles /Arizona Z mounts/ Daves wilwood brake set up  . I always worry I am going to break this set up … on street tires so far its held up but I don't torture it ,or abuse it to bad ….a  picture of the car at beaches car show behind the band stage held every Wednesday night from June threw September largest  car show held weekly on the west coast ,usually from 1200 - 2300 cars are there ..

Obviously I can't stop to take pictures of everything going out the door, but here's a couple more uprights set up for 2015 brakes and hubs tacked up for someone.

 

Oh and shout out to summers brothers racing.  They make a kickass set of axles for this conversion.  Roughly a dozen pairs so far and the fitment is amazing.

How much are the axles and what power level will they hold?

 

Thanks

 Shafts themselves are rated to 800tq, 8 ball v8 mustang cv ratings are unknown but whole assembly has been kicking butt on an 800hp car with zero issues since install.

 

As per forum rules prices cannot be discussed in the technical threads, so PM me and I'll gladly let you know everything.

 

To put it in perspective though... complete pair including low mileage v8 cv usually ends up costing less than the discontinued oem Nissan turbo z32 axle PER SHAFT... IF you can get them.

 

We're talking about 34 spline inner stubs, 8 ball cv, heat treated custom shafts and 32 spline outer using a bolt on hub with a SUBSTANTIAL bearing size to boot.

Heck ya, axles looking good.

 

Btw, 2018 mustang stick v8 cars are using gt350 axles.

 

Gt350 axles are basically the same right axle, but the left has been increased in diameter and cv size.  They will not work for this conversion.

 

So you need v8 axles 2015 to 2017 and 2018 must be v8 automatic axles.
