That 10 spd is direct correct? The 9spd was OD?

My triplex and 4.10 will go 72 at 2100 rpm. 65 is 1800 rpm. So yours should go 65 at 2100 rpm.

I can drag my trailer at 72mph, though it drops off with any kind of grade. Usually 65 is good.

I was concerned with my gear choice at first, but surprisingly it does pretty well for the power it has. Originally the air ride clip had 3.70s and I knew that was wayyy too fast so I got 4.10's for it instead.

You'l be fine.
