amazing what I can do on the highway with no headwind.
could have gone even faster but the area is lousy for sheriffs.
but with a headwind, I top out around 71. so I made the decision to order some gears.
got 4.56s. the 3.73 I have now with the big ass 22s is like having a 3.23 rear end and it just gets smacked trying to climb the aero load. the truck needs some torque multiplication. I would have ordered 4.30s, that would have brought me back to a 3.73 effective, but they were literally twice the price. this way I get a 4.10 effective on the overdrive, which should help even more.
I will have them installed when I shorten the driveshaft this week (assuming they show up in two days like they say)
