From my past Arrma exper, if it doesn't say it's 7075 T6 anywhere.... it most definitely is NOT 7075 alloy. Probably is just some 6061 if even that, some Chinesium alloy or whatever. Pot luck. Doesn't even spec. 6061....or anything.
Also that EXB Bulkhead doesn't come with an oversized Outer Input gear BB, like 99% of upgrade brand ones do. If I got the actual new K6 EXB, I would deal with it. But going to upgrade to an alloy EXB Bulkhead, I would not consider buying them, Upgrade brand Bulkheads are way better for this reason alone. Those smaller undersized Stocker input gears BBs fail often. A weak link in the drivetrain. I still run the plastic stocker bulkheads, but buy the stocker size Outer Input gear BB's in bulk. Works for me. Always installing a fresh BB there when I rebuild my diffs. If you neglect it and wait til that outer BB explodes on you, you will trash the whole diff. Promise.

>>>Arrma/HH's Marketing Dept would absolutely embellish the 7075 spec if it truly was.


This is one example from ADU. In 7075 T6 and there are many other brands. Make sure it has an oversized, Input gear Outer BB, whatever you choose. Verify this first. Best advice, IMHO.
