I need a solid/straight axle and diff that will handle 40-50 mph, possibly more, for a project I'm working on. It needs to be at least 1/12 scale, but I would prefer 1/10 or 1/8. I was considering the Wheely King axle, but because the truck isn't that fast, I can't see it being that strong. What I would like, is aluminum, and a 4-link setup for both sides, plus a place to mount shocks on the rear.

I hope you guys can help, thanks.
