They're chromoly. Supposed to be about 4lbs weight savings. I have bought two sets already and am happy with them. They fit decent and they're no stronger than stock IMO which was my biggest concern being chromoly. I want to bent a arms, not crack my bulkhead.
The only reason for me to change front ends is to narrow the stance of the assault.
I hope geometry remains the same
Weight isn't a concern of mine
Strength is an interesting topic, regardless of opinion: when the time comes, something has to give give and I don't want to damage the bulk head
