I was wondering if a zenki gts lsd axle will work with an open diff. If anyone could give me some info on that I would appreciate it.

Yes.

as long as its a zenki open diff

Thanks appreciate it. Was just going to try to source an open diff, but decided to get a spool from weir performance. If any of you run one can you clarify if it will take both lsd and open diff axles like most lsd units.
