Call me crazy, but it looks like the Vinson and the Eiger have the same front diff except for the actuator. SO, do they have the same CV axles? Do they have the same control arms? Looks like all that stuff is the same, and the only reason the Vinson is wider is because the backspacing on the aluminum wheels is different than the steel ones on the Eiger.

I don't remember looking closely at the rear axle... is it the same except for the disk brake?

 

i think the a-arms are different, and the rear end because of the swing arm.

 

How is the swing arm different?
