Is there such a thing as IRS rear end with the horns attached from factory or have they been added on later by someone as extra strength?

Just needing to buy a subframe so I can mock up my 915 box and didnt want to source a IRS rear end if I was getting something wrong.

Cheers, Andrew

Hi Andrew,

I'm no expert but I do not think so. I've just had two rear ends combined into one as in this thread:

All the best.
