So far this is the best Yeti Thread ever.
Thanks!

Great news on the Diff casings and gears. It means we can use HR or other stronger diff casings and the HPI spider gears. In other words I already have a set of replacement spider gears and paper gaskets.

Does anyone have a twin hammers to measure those trailing arms? And blue monkey wraith ones? That would be phenomenal.

Josh, can you get us the rear sway bar lengths?

I think I can get all those dimensions for you. The Blue Monkey links are definitely shorter but I'm sure he'll have some for the Yeti soon based on his posts.

Rear wb8 drive shaft length too!!!

Sorry, what rear SLW matches the front being the .225 you tested?

[Hunter711]
