I don't want to make it seem like I'm trying to push a product, but here is another option for spec.B rear axles.

What are all of your thoughts on rear axles with no HP limit and a lifetime no questions asked warranty, for around $1k? If you do manage to break it, a stronger replacement will be made for you.
My intent for the spec.B was to be my daily driver for my modified Jeep Wrangler. Then I thought to myself, "I'll just go stage 2 and leave it there."
Then a ringland went. Then down the rabbit hole I fell.
I no longer have the Wrangler and bought a DD for my DD.
Stay tuned for the new build to be revealed soon.
Motor and trans are out. Just waiting for the time to put the new stuff in.
This round is voluntary. Everything was running absolutely perfect for over 12k miles.
