how does this work? is this a matter of changing out the gears in the rear diff to get a different final drive ratio? how do you know what to go to?
I'm an Infiniti tech, so I mounted and balanced them myself. I've road forced balanced them, etc. can't get them right. I've tried all 3 tire balancers at work and it's the same thing. Starts at about 62mph. Pretty much is gone at 68mph, but comes back at anything over 70. I'm not super comfortable pushing the truck much over 70mph since I have 4.88's, but it's annoying.
Edit; I've also calibrated the balancer thinking maybe it was off, but no go. I may just bite the bullet and have a tire shop try and see what they come up with.
Think of it like riding a 10-speed bike. You're going to essentially raise the ratio to get better acceleration (the low gears on the bike), but you'll lose top end. You'll have to do the front AND rear.
So for example, I have 4.88's in mine. That equates to 4.88 driveshaft revolutions to one full rotation of the tire.
Hmmm, I was a manager at discount tire for years and anytime we ever came across that issue was a wheel was bent ever so slightly (out of round), this would be discovered with the tire dismounted and put on balancing machine and watch it spin.
We always had problems with tuner cars using non hubcentric wheels and not using hub rings due to not taking the time to find the right ones so there was always some play and their thought process of overtightening lug nuts would get it right.
Don't get me started on ET lugs.
Anyways, quick fix is balancing beads.
When you roadforced the tires did it want you to rotate any of the tires to a different position of rim?
I'd check for out of round or warping of the wheels with tires off
Yup, had to rotate 2 tires on the brand new rims I bought. I once did balance beads on my Tacoma on 37's and it was terrible.
You have to get the right amount/ weight of beads to make it work right. All my tires are balanced that way.

Where's the thread on this or is there none? I'd be curious to follow.
I used the chart I found from one of the bead manufacturers. If I remember correctly, I used 10oz a tire for the 37's.
One of my tires didn't balance at first until i dismounted it from the wheel, rotated it about 180 degrees and put the beads back in.
I didn't put up a thread, not enough time in the day. Basically this is being done to fix compression drop, went from 140 when I base lined it when I picked up the 60 in 2011 at 140-150, after a few years now at 80-90. I"m sure sea Foam would have possiable fixed it,m but it allows me to address any other potential issues.
Had a spare 2F head that @GRM said here take this I don't want to take it home and you might need it some day from Georg's swap 2 years ago.
Had the spare head sent out check and machined (.015 taken off), new springs, valve seals and the oil galley plug fixed. Things I learned the air injection rail is very fragile and sometime no matter how much PB blaster you will still break one of the fittings. Good thing @PbnFJ happened to have a rail in his parts pile while it was a bit bent we were able to straighten it out and had to rebraze one of the injection pipes.
Today is bolting backing on the thermostat housing and the intake/exhaust manifold back to the block, and putting everything else back together and firing it up.
Also decided that this would be the perfect time to put in my Saginaw PS pump conversion after getting all the parts from @orangefj45.

So your in Cali (speaking of Georg) Whoops, I see you wrote Gerod... I read wrong. Was gonna ask how the valves looked but I gather a different climate would affect the system different from on the East coast. Interesting that they went low. What does a drop indicate different from a rise in compression?
Nice spot. I've never seen your rig around ABQ
