There's gonna be an SWB version as well, but you can't swap parts between them for obvious reasons. SWB version:
Decided to throw proper duallies in game just cause I got annoyed by the lack of them on 8 lug wheels
Ugh... My memory may be fooling me, but AFAIK there are duallies on 8-lug wheels for the D-Series... Unless you mean something else
there are duallies, but go into your game turn on debug drawing for beams and nodes and check what is different the ones we have now are just a one big wheel instead of 2 smaller ones
