Ive never heard of anyone bending or breaking a currie. Yeah i would agree that maybe the Rokmens are extra weight, but if you like to overbuild, then having that extra weight that much lower is better than running steel corner armor or steel tube fenders like a lot of people do.
And that's how it starts. Oh, don't worry about a bit of weight on the arms, it's in a good spot. That's alright, a bit of extra weight on a belly skid won't hurt, besides, it's in a good spot down low. Yeppers, you won't even notice a few extra pounds on an engine skid, go ahead and get a real beefy one.
No no, really, 40 lb diff covers are just fine, you can't even tell. Besides, with those steel rims, you aren't even adding the weight of one of those.
Before you know it, you run your rig across the scale and you've got another thousand pounds of crap weight additional, but hey, it's all in the right place.
Sorry, the right place is on someone else's rig.
