Cooked my aluminum diff so going to build a cast iron one. Is there any Aftermarket diff that will work with 3.15 gears? I've heard some people using a Wavetrac but Wavetrac said it wouldnt work. Please let me know what you guys think or know of any that will.

Ive been running WaveTrac for 3 years now with 800+ and it has held up great. Im running a 4.09 because of my trans combo. If I remember right there is something different about the 3.15s. I got mine through @beefcake , he can probably shed more light.

You can get a 3.15 specific Torsen.

Hi all,

I talked to Terry from beefcake, he was very helpful, but aftermarket for 3.15 is pretty much nonexistent which is crazy to me with many people running them.

@Brazos69 I did find the Torsten you are talking about but they are out of stock and ended up leaving a voicemail to see when it would be in stock again.

I’m trying to stay out of 7th gear, can only do that with 3.15s. I’m at bout 900whp with a Whipple.
