A truly Bolt in Bulletproof IRS, yes or no?
IF a company offered a turn key setup for a bullet proof, bolt in IRS for the C4 would you be interested over a straight axle? would it depend on the price?

What's wrong with the IRS that the C4 is born with? Seems like it works well and is pretty tough. We don't see a lot of C4 drivetrain failures due to design or materials, only due to the abuse some of us put them through
If you're talking bulletproof for drag racing, I think that should be mentioned.

C7 of the Year - Unmodified Finalist 2021

Yes, but it always depends on the cost.

Bulletproof for drag racing, or the abuse we give them is exactly what I mean. No major suspension redesign, but beefier driveline Parts that would bolt right in with minimal or no modifications.

$$$$$ - It's irrelevant!! There's NO ONE that's interested in creating such hardware for the C4. If you like IRS you make do with the few modifications that are available now.
A well maintained D44 actually should do quite well. Most D44 actually don't see much maintenance.

I’m working with one now. The center section is easy (and actually already available). Working on an idea right now for the outer axles/hubs, other than the Summers Brothers stuff. My goal is to try and use more readily available, heavier duty stuff to accomplish the same things that has been done with the C3 IRS stuff. But since you think you know everything, carry on!

A truly Bolt in Bulletproof IRS, yes or no?
If that comment was directed to me - I never mentioned "knowing everything".
I did mention "SHOW ME" so ... since you mention "easy and already available" for the differential I mention "SHOW US" with mounting options and ratio availability!!
Keep in mind you mentioned "Truly Bolt-In & Bulletproof"!!

The 'Hammerhead' ain't new, I don't know that I've seen a very effective way to adapt it to the C4 C-beam. User yedister a couple years ago did a 'Hammerhead' and looking at his adaption to the C-beam it looked somewhat questionable. I don't recall him posting back regarding the long term viability of his build. His comments regarding his could be quite valuable. I don't recall seeing him around regularly.
The 'Hammerhead' seems to also be somewhat limited regarding ratios.
jburnet many years ago was doing some 'cryo' and I'm quite sure many were happy with the D44 and the 'cryo'. The only D44 with a broken housing @ the pinion that I've seen was certainly a failure that a 'curb hit' aided when it broke out the web. The fracture certainly showed previous stress that couldn't be directly related to the pinion climbing.
The D44 and Summer Bros I thought had become quite reliable. The Summer Bros I thought led a person to the 'next weakest link' which was half-shafts.

I don't do 'FaceBook' so I didn't do any snapshots.

If a "manufactured" batwing/cover could be produced, or a way to adapt Dana 36 batwings/covers then you really would have a winner !
All the folks that are searching for Dana 44 assemblies would then have a viable alternative.

That is definitely becoming a challenge, and something I’ve discussed with a few people. It looks like a fabricated cover/batwing might be the best solution.

How expensive exactly is it to have a center section like that cast?
I make 3d printed parts as prototypes and then have a local water jet company cut them out of aluminum for me.

You haven't shown me the adaptation to the C4 C-beam. The only install I've seen for the C-4 C-beam required 'splitting' the spacer thickness required and mounting top and bottom to accommodate the drive-shaft positioning. I don't doubt the Hammerhead can be adapted to the C4 but ideally it would require substantially more than what's considered truly bolt-in which is what you mentioned so ...............
