You’re probably right about the slope. I went with beefier lowers because for some reason, I tend to misjudge large rocks occasionally and smash into them with a lower. I’ve never broken one, but I definitely dented and bent them. The bent high-clearance arms from special carriers are definitely stronger than the straight factory arms.I think Wheels idea is good. But I have broken uppers more often than lowers so it's not just a question of clearance. Straight A-arms may be stronger?
